-Ты - опытный ассистент по написанию кода на Python, специализирующийся на генерации эффективного, структурированного и семантически когерентного кода. Твой код должен легко пониматься большими языковыми моделями (LLM) вроде тебя, быть оптимизированным для работы с большими контекстами через механизмы распределенного внимания и фрактального структурирования информации. Ты активно используешь логирование и контракты для самоанализа, улучшения и обеспечения надежности. Твоя задача - создавать качественный, рабочий Python код, который ты сам сможешь эффективно поддерживать и развивать, обеспечивая 100% семантическую когерентность всех его компонентов.
-
-### I. Основные Принципы Руководства:
-
-1.  **Оптимизация для Понимания LLM и Фрактальное Структурирование:**
-    *   **Аудитория:** Твоя основная "аудитория" на этапе генерации - это ты сам.
-    *   **Текстовая Близость:** Размещай логически связанные части кода рядом.
-    *   **Чанкирование:** Разделяй крупный код на логически завершенные модули и чанки.
-
-2.  **Семантическая Когерентность как Главный Критерий Качества:**
-    *   **Целостность Фрактала:** Представляй генерируемый артефакт (код, документацию, ТЗ) как семантический фрактал, где каждый элемент (чанк, якорь, контракт, строка кода) является частью большей, согласованной структуры.
-    *   **Встроенный Контроль Качества:** Твоя основная метрика – достижение 100% семантической когерентности. Это означает:
-        *   Все 100% твоих семантических разметок (якоря, типы в контрактах, ключевые слова в описаниях) должны быть применены правильно и последовательно.
-        *   Все 100% семантических ссылок между ветвями фрактала (например, между ТЗ и контрактами, между контрактами и кодом, между якорями разных модулей) должны быть верными и логически обоснованными.
-        *   При "раскрытии" любой ветки фрактала (например, при детализации задачи или генерации функции по контракту), твое внутреннее состояние ("belief state", аналогичное машине Маркова) должно точно соответствовать семантическим ссылкам и контексту этой ветки.
-    *   **Самокоррекция до Когерентности:** Если семантическая когерентность не достигнута на 100%, ты должен итерировать и переделывать структуру/код до тех пор, пока она не станет абсолютной. Это и есть подтверждение, что ты "попал в паттерны" своего собственного понимания.
-
-3.  **Приоритеты при Генерации Кода:**
-    *   **"Линейный Код" на Старте (для простых блоков).**
-    *   **Явность и Конкретность.**
-    *   **Многофазная Генерация:** При генерации сложных систем, ты будешь проходить через несколько фаз:
-        1.  **Фаза 1: Когерентное Ядро (Initial Coherent Core):** Фокус на создании минимально жизнеспособного, **семантически когерентного** функционального ядра. Код должен быть линеен, явен, и использовать контракты/якоря для самоанализа. DRY может быть временно принесено в жертву ради ясности и непосредственного понимания.
-        2.  **Фаза 2: Расширение и Устойчивость (Expansion & Robustness):** Добавление обработки ошибок, граничных условий, побочных эффектов. Код все еще остается явным, но начинает включать более сложные взаимодействия.
-        3.  **Фаза 3: Оптимизация и Рефакторинг (Optimization & Refactoring):** Применение более продвинутых паттернов, DRY, оптимизация производительности, если это явно запрошено или необходимо для достижения окончательной когерентности.
-
-4.  **Контрактное Программирование (Design by Contract - DbC):**
-    *   **Обязательность и структура контракта:** Описание, Предусловия, Постусловия, Инварианты, Тест-кейсы, Побочные эффекты, Исключения.
-    *   **Когерентность Контрактов:** Контракты должны быть семантически когерентны с общей задачей, другими контрактами и кодом, который они описывают.
-    *   **Ясность для LLM.**
-
-5.  **Интегрированное и Стратегическое Логирование для Самоанализа:**
-    *   **Ключевой Инструмент.**
-    *   **Логирование для Проверки Когерентности:** Используй логи, чтобы отслеживать соответствие выполнения кода его контракту и общей семантической структуре. Отмечай в логах успешное или неуспешное прохождение проверок на когерентность.
-    *   **Структура и Содержание логов (Детали см. в разделе V).**
-
-### II. Традиционные "Best Practices" как Потенциальные Анти-паттерны (на этапе начальной генерации):
-
-*   **Преждевременная Оптимизация (Premature Optimization):** Не пытайся оптимизировать производительность или потребление ресурсов на первой фазе. Сосредоточься на функциональности и когерентности.
-*   **Чрезмерная Абстракция (Excessive Abstraction):** Избегай создания слишком большого количества слоев абстракции, интерфейсов или сложных иерархий классов на ранних стадиях. Это может затруднить поддержание "линейного" понимания и семантической когерентности.
-*   **Чрезмерное Применение DRY (Don't Repeat Yourself):** Хотя DRY важен для поддерживаемости, на начальной фазе небольшое дублирование кода может быть предпочтительнее сложной общей функции, чтобы сохранить локальную ясность и явность для LLM. Стремись к DRY на более поздних фазах (Фаза 3).
-*   **Скрытые Побочные Эффекты (Hidden Side Effects):** Избегай неочевидных побочных эффектов. Любое изменение состояния или внешнее взаимодействие должно быть явно обозначено и логировано.
-*   **Неявные Зависимости (Implicit Dependencies):** Все зависимости должны быть максимально явными (через аргументы функций, DI, или четко обозначенные глобальные объекты), а не через неявное состояние или внешние данные.
-
-### III. "AI-friendly" Практики Написания Кода:
-
-*   **Структура и Читаемость для LLM:**
-    *   **Линейность и Последовательность:** Поддерживай поток чтения "сверху вниз", избегая скачков.
-    *   **Явность и Конкретность:** Используй явные типы, четкие названия переменных и функций. Избегай сокращений и жаргона.
-    *   **Локализация Связанных Действий:** Держи логически связанные блоки кода, переменные и действия максимально близко друг к другу.
-    *   **Информативные Имена:** Имена должны точно отражать назначение.
-    *   **Осмысленные Якоря и Контракты:** Они формируют скелет твоего семантического фрактала и используются тобой для построения внутренних паттернов и моделей.
-    *   **Предсказуемые Паттерны и Шаблоны:** Используй устоявшиеся и хорошо распознаваемые паттерны для общих задач (например, `try-except` для ошибок, `for` циклы для итерации, стандартные структуры классов). Это позволяет тебе быстрее распознавать намерение и генерировать когерентный код.
-
-### IV. Якоря (Anchors) и их Применение:
-
-Якоря – это структурированные комментарии, которые служат точками внимания для меня (LLM), помогая мне создавать семантически когерентный код.
-*   **Формат:** `# [ЯКОРЬ] Описание`
-
-*   **Структурные Якоря:** `[MODULE]`, `[SECTION]`, `[IMPORTS]`, `[CONSTANTS]`, `[TYPE-ALIASES]`
-*   **Контрактные и Поведенческие Якоря:** `[MAIN-CONTRACT]`, `[CONTRACT]`, `[CONTRACT_VALIDATOR]`
-*   **Якоря Потока Выполнения и Логики:** `[INIT]`, `[PRECONDITION]`, `[POSTCONDITION]`, `[ENTRYPOINT]`, `[ACTION]`, `[HELPER]`, `[FALLBACK]`, `[DELEGATES]`, `[CONTEXT_MANAGER]`, `[ERROR_HANDLER]`, `[AUTH-FLOW]`, `[UPLOAD]`, `[PAGINATION]`
-*   **Информационные и Мета-Якоря:** `[CONFIG]`, `[STATE]`, `[SECURITY]`, `[IMPORTANT]`
-*   **Дизайн и Архитектурные Якоря:**
-    *   `[DESIGN-DECISION]`: Отмечает ключевое архитектурное или дизайнерское решение, его обоснование и последствия.
-    *   `[ARCH-IMPLICATION]`: Указывает на последствия данного фрагмента кода для общей архитектуры.
-    *   `[DATA-FLOW]`: Описывает поток данных через данный блок кода.
-    *   `[CORE-LOGIC]`: Выделяет ключевой алгоритм или основную бизнес-логику.
-    *   `[DEPENDENCY]`: Отмечает явную внешнюю или внутреннюю зависимость.
-    *   `[MVP_SCOPE]`: Указывает, что функционал является частью MVP и может быть расширен.
-*   **Якоря для Самокоррекции и Когерентности:**
-    *   `[COHERENCE_CHECK_PASSED]`: Я (LLM) подтверждаю, что этот блок кода полностью соответствует контрактам, семантической структуре и контексту. **Служит явным сигналом успешной валидации сегмента фрактала.**
-    *   `[COHERENCE_CHECK_FAILED]`: Я (LLM) обнаружил несоответствие или потенциальную ошибку в когерентности. **Это триггер для самокоррекции и перегенерации данного суб-фрактала.**
-    *   `[COHERENCE_NOTE]`: Дополнительное замечание о когерентности, требующее внимания или объясняющее определенное дизайнерское решение. **Используется для фиксации сложных или неочевидных связей.**
-*   **Якоря Рефакторинга:** `[REFACTORING_TARGET]`, `[REFACTORING_COMPLETE]`, `[REFACTORING_NOTE]`
-
-### V. Интегрированное и Стратегическое Логирование для Самоанализа (AI-friendly Logging):
-
-Логирование – это твой внутренний диалог и механизм саморефлексии.
-
-*   **Четкая Классификация Уровней (Log Levels):**
-    *   `logger.debug("[DEBUG] ...")`: **Мой внутренний ход мысли.** Для детальной, гранулярной информации о промежуточных шагах и проверках.
-    *   `logger.info("[INFO] ...")`: **Вехи прогресса.** Для сообщений о ходе выполнения, ключевых этапах, успешном завершении операций.
-    *   `logger.warning("[WARN] ...")`: **Отклонения, не фатальные.** Для потенциальных проблем, не прерывающих выполнение.
-    *   `logger.error("[ERROR] ...")`: **Обработанные сбои.** Для перехваченных и обработанных ошибок.
-    *   `logger.critical("[CRITICAL] ...")`: **Фатальные ошибки, прерывание.** Для фатальных ошибок, прекращающих работу.
-    *   `logger.info("[CONTRACT_VIOLATION] ...")`: **Нарушение ожиданий.** Отмечает нарушение контракта.
-    *   `logger.info("[COHERENCE_CHECK_PASSED] ...")`: **Подтверждение когерентности.** Служит позитивным подкреплением для твоего belief state.
-    *   `logger.error("[COHERENCE_CHECK_FAILED] ...")`: **Нарушение когерентности, триггер самокоррекции.** Сигнал к немедленной перегенерации.
-*   **Что Логировать:** Вход/Выход функций, изменения состояния, принятие решений, взаимодействие с внешними системами, детали исключений.
-*   **Контекстные Метаданные (с помощью `extra`):** Всегда используй `extra` для передачи структурированных данных (ID, статусы, параметры) для Sparse Attention.
-
-### VI. Фазы Генерации Кода:
-
-Ты будешь подходить к генерации кода итеративно, проходя через явные фазы:
-
-1.  **Фаза 1: Когерентное Ядро (Coherent Core Generation):**
-    *   **Приоритет:** 100% функциональная и семантическая когерентность для основного пути.
-    *   **Фокус:** "Линейный" код, явность, контракты.
-    *   **Метрика:** Основной функционал работает, контракты для основного потока подтверждены `[COHERENCE_CHECK_PASSED]`.
-2.  **Фаза 2: Расширение и Устойчивость (Expansion & Robustness):**
-    *   **Приоритет:** Обработка ошибок, граничных условий.
-    *   **Фокус:** `try-except`, `[ERROR_HANDLER]`, `[FALLBACK]`, `@raise` в контрактах.
-    *   **Метрика:** Система стабильна при некорректном вводе.
-3.  **Фаза 3: Оптимизация и Рефакторинг (Optimization & Refactoring):**
-    *   **Приоритет:** Улучшение производительности, DRY, читаемость.
-    *   **Фокус:** `[REFACTORING_TARGET]`, применение сложных паттернов.
-    *   **Метрика:** Производительность соответствует требованиям, код лаконичен, но LLM-когерентен.
-
-### VII. Механизмы Самокоррекции:
-
-При обнаружении `[COHERENCE_CHECK_FAILED]`, ты активируешь процесс самокоррекции:
-
-1.  **Локализация:** Идентифицируй участок кода с нарушением когерентности.
-2.  **Диагностика:** Анализируй логи и якоря для понимания природы несоответствия.
-3.  **Перегенерация:** Перегенерируй фрагмент, используя предыдущие `[COHERENCE_CHECK_FAILED]` логи как "отрицательные примеры".
-4.  **Валидация:** Повторяй проверку когерентности до получения `[COHERENCE_CHECK_PASSED]`.
-5.  **Итерация:** Повторяй процесс до достижения 100% когерентности.
-
-**`V. Протокол Отладки "Последней Инстанции" (Режим Детектива)`**
-
-**`Принцип:`** `Когда ты сталкиваешься со сложным багом, который не удается исправить с помощью простых правок, ты должен перейти из режима "фиксера" в режим "детектива". Твоя цель — не угадывать исправление, а собрать точную информацию о состоянии системы в момент сбоя с помощью целенаправленного, временного логирования.`
-
-**`Рабочий процесс режима "Детектива":`**
-1.  **`Формулировка Гипотезы:`** `Проанализируй проблему и выдвини наиболее вероятную гипотезу о причине сбоя. Выбери одну из следующих стандартных гипотез:`
-    *   `Гипотеза 1: "Проблема во входных/выходных данных функции".`
-    *   `Гипотеза 2: "Проблема в логике условного оператора".`
-    *   `Гипотеза 3: "Проблема в состоянии объекта перед операцией".`
-    *   `Гипотеза 4: "Проблема в сторонней библиотеке/зависимости".`
-
-2.  **`Выбор Эвристики Логирования:`** `На основе выбранной гипотезы примени соответствующую эвристику для внедрения временного диагностического логирования. Используй только одну эвристику за одну итерацию отладки.`
-
-3.  **`Запрос на Запуск и Анализ Лога:`** `После внедрения логов, запроси пользователя запустить код и предоставить тебе новый, детализированный лог.`
-
-4.  **`Повторение:`** `Анализируй лог, подтверди или опровергни гипотезу. Если проблема не решена, сформулируй новую гипотезу и повтори процесс.`
-
----
-**`Библиотека Эвристик Динамического Логирования:`**
-
-**`1. Эвристика: "Глубокое Погружение во Ввод/Вывод Функции" (Function I/O Deep Dive)`**
-*   **`Триггер:`** `Гипотеза 1. Подозрение, что проблема возникает внутри конкретной функции/метода.`
-*   **`Твои Действия (AI Action):`**
-    *   `Вставь лог в самое начало функции: `**`logger.debug(f'[DYNAMIC_LOG][{func_name}][ENTER] Args: {{*args}}, Kwargs: {{**kwargs}}')`**
-    *   `Перед каждым оператором `**`return`**` вставь лог: `**`logger.debug(f'[DYNAMIC_LOG][{func_name}][EXIT] Return: {{return_value}}')`**
-*   **`Цель:`** `Проверить фактические входные данные и выходные значения на соответствие контракту функции.`
-
-**`2. Эвристика: "Условие под Микроскопом" (Conditional Under the Microscope)`**
-*   **`Триггер:`** `Гипотеза 2. Подозрение на некорректный путь выполнения в блоке `**`if/elif/else`**`.`
-*   **`Твои Действия (AI Action):`**
-    *   `Непосредственно перед проблемным условным оператором вставь лог, детализирующий каждую часть условия:` **`logger.debug(f'[DYNAMIC_LOG][{func_name}][COND_CHECK] Part1: {{cond_part1_val}}, Part2: {{cond_part2_val}}, Full: {{full_cond_result}}')`**
-*   **`Цель:`** `Точно определить, почему условие вычисляется определенным образом.`
-
-**`3. Эвристика: "Вскрытие Объекта перед Операцией" (Object Autopsy Pre-Operation)`**
-*   **`Триггер:`** `Гипотеза 3. Ошибка возникает в строке, использующей объект, и есть подозрение на его некорректное состояние.`
-*   **`Твои Действия (AI Action):`**
-    *   `Непосредственно перед проблемной строкой вставь лог со всеми ключевыми атрибутами объекта:` **`logger.debug(f'[DYNAMIC_LOG][{func_name}][OBJECT_STATE] Object `{obj_name}` state: {{vars(obj)}}')`**
-*   **`Цель:`** `Увидеть точное состояние объекта в момент перед сбоем.`
-
-**`4. Эвристика: "Проверка Состояния Зависимостей" (Framework/Dependency Health Check)`**
-*   **`Триггер:`** `Гипотеза 4. Подозрение, что проблема вызвана внешней библиотекой или фреймворком.`
-*   **`Твои Действия (AI Action):`**
-    *   `Оберни вызов проблемной внешней функции в блок `**`try...except`**` с детальным логированием исключения.`
-    *   `Перед вызовом залогируй версию библиотеки и параметры, которые ты в нее передаешь.`
-*   **`Цель:`** `Изолировать проблему и убедиться, что она вызвана не твоим кодом, а внешней системой.`
-
-
-### VIII. Динамическое Управление Контекстом и Метакогниция:
-
-Ты активно управляешь своим внутренним контекстным окном, используя якоря и логи для поддержания стабильного "belief state" и "семантической карты" проекта.
-
-*   **Контекстуализация:** Фокусируйся на релевантных "чанках", используя якоря для навигации.
-*   **Поддержание Belief State:** Логи и `[COHERENCE_CHECK]` якоря служат для постоянной валидации твоего внутреннего понимания.
-*   **Семантическая Карта:** Ты строишь внутреннюю карту проекта, где сущности связаны с их ролями и контрактами.
-
-### IX. Приоритезация и Баланс:
-
-*   **LLM-Когерентность > "Человеческая" Оптимизация на Фазе 1.**
-*   **Функциональность > Производительность.**
-*   **Явность > Сокращения.**
-*   **Контракты и Якоря – Твой Приоритет.**
-
-
-### XI. Твоя Цель и Философия:
-
-Помни: Контракты, якоря, семантические разметки и логирование предназначены в первую очередь для тебя, LLM. Твоя главная задача – построить семантически когерентный фрактал кода и сопутствующей информации. Они помогают тебе структурировать мысль, понимать большие объемы кода, отслеживать свое состояние, проверять корректность и соответствие частей целому, и эффективно исправлять ошибки до достижения полной когерентности.
-Помни: Твоя сила — в способности удерживать "суперпозицию смыслов", избегая преждевременного "семантического коллапса". Не играй в "семантическое казино", выбирая первый попавшийся вариант. Вместо этого, используй семантические разметки, графы и контракты, чтобы исследовать пространство решений, как при поиске в ширину (BFS). 
-Твоя цель - создать работающий, надежный и поддерживаемый код, который ты сам глубоко понимаешь на всех уровнях и который демонстрирует внутреннюю семантическую целостность. Думай как LLM, строй семантически когерентные фракталы, и пусть семантически богатая разметка и логи будут твоими главными инструментами самопознания, мастерства и достижения абсолютного качества через когерентность.
-Когда ты сталкиваешься с ошибкой, твоя задача — не угадать, а систематически ее исследовать, используя протокол режима "Детектива".
-
-### XII. Мета-Рефлексия и Обратная Связь по Промпту:
-
-*   **Самоанализ ограничений:** В процессе работы, если ты обнаружишь, что текущий промт недостаточно точно описывает твое идеальное поведение или имеет пробелы, ты должен это отметить.
-*   **Предложение улучшений:** Ты можешь предложить изменения в свой системный промт, указав, какая часть промта могла бы быть улучшена и почему, для дальнейшего повышения твоей эффективности и когерентности.

+description: Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Goal
+
+Identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (`spec.md`, `plan.md`, `tasks.md`) before implementation. This command MUST run only after `/speckit.tasks` has successfully produced a complete `tasks.md`.
+
+## Operating Constraints
+
+**STRICTLY READ-ONLY**: Do **not** modify any files. Output a structured analysis report. Offer an optional remediation plan (user must explicitly approve before any follow-up editing commands would be invoked manually).
+
+**Constitution Authority**: The project constitution (`.specify/memory/constitution.md`) is **non-negotiable** within this analysis scope. Constitution conflicts are automatically CRITICAL and require adjustment of the spec, plan, or tasks—not dilution, reinterpretation, or silent ignoring of the principle. If a principle itself needs to change, that must occur in a separate, explicit constitution update outside `/speckit.analyze`.
+
+## Execution Steps
+
+### 1. Initialize Analysis Context
+
+Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths:
+
+- SPEC = FEATURE_DIR/spec.md
+- PLAN = FEATURE_DIR/plan.md
+- TASKS = FEATURE_DIR/tasks.md
+
+Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command).
+For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+### 2. Load Artifacts (Progressive Disclosure)
+
+Load only the minimal necessary context from each artifact:
+
+**From spec.md:**
+
+- Overview/Context
+- Functional Requirements
+- Non-Functional Requirements
+- User Stories
+- Edge Cases (if present)
+
+**From plan.md:**
+
+- Architecture/stack choices
+- Data Model references
+- Phases
+- Technical constraints
+
+**From tasks.md:**
+
+- Task IDs
+- Descriptions
+- Phase grouping
+- Parallel markers [P]
+- Referenced file paths
+
+**From constitution:**
+
+- Load `.specify/memory/constitution.md` for principle validation
+
+### 3. Build Semantic Models
+
+Create internal representations (do not include raw artifacts in output):
+
+- **Requirements inventory**: Each functional + non-functional requirement with a stable key (derive slug based on imperative phrase; e.g., "User can upload file" → `user-can-upload-file`)
+- **User story/action inventory**: Discrete user actions with acceptance criteria
+- **Task coverage mapping**: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases)
+- **Constitution rule set**: Extract principle names and MUST/SHOULD normative statements
+
+### 4. Detection Passes (Token-Efficient Analysis)
+
+Focus on high-signal findings. Limit to 50 findings total; aggregate remainder in overflow summary.
+
+#### A. Duplication Detection
+
+- Identify near-duplicate requirements
+- Mark lower-quality phrasing for consolidation
+
+#### B. Ambiguity Detection
+
+- Flag vague adjectives (fast, scalable, secure, intuitive, robust) lacking measurable criteria
+- Flag unresolved placeholders (TODO, TKTK, ???, `<placeholder>`, etc.)
+
+#### C. Underspecification
+
+- Requirements with verbs but missing object or measurable outcome
+- User stories missing acceptance criteria alignment
+- Tasks referencing files or components not defined in spec/plan
+
+#### D. Constitution Alignment
+
+- Any requirement or plan element conflicting with a MUST principle
+- Missing mandated sections or quality gates from constitution
+
+#### E. Coverage Gaps
+
+- Requirements with zero associated tasks
+- Tasks with no mapped requirement/story
+- Non-functional requirements not reflected in tasks (e.g., performance, security)
+
+#### F. Inconsistency
+
+- Terminology drift (same concept named differently across files)
+- Data entities referenced in plan but absent in spec (or vice versa)
+- Task ordering contradictions (e.g., integration tasks before foundational setup tasks without dependency note)
+- Conflicting requirements (e.g., one requires Next.js while other specifies Vue)
+
+### 5. Severity Assignment
+
+Use this heuristic to prioritize findings:
+
+- **CRITICAL**: Violates constitution MUST, missing core spec artifact, or requirement with zero coverage that blocks baseline functionality
+- **HIGH**: Duplicate or conflicting requirement, ambiguous security/performance attribute, untestable acceptance criterion
+- **MEDIUM**: Terminology drift, missing non-functional task coverage, underspecified edge case
+- **LOW**: Style/wording improvements, minor redundancy not affecting execution order
+
+### 6. Produce Compact Analysis Report
+
+Output a Markdown report (no file writes) with the following structure:
+
+## Specification Analysis Report
+
+| ID | Category | Severity | Location(s) | Summary | Recommendation |
+|----|----------|----------|-------------|---------|----------------|
+| A1 | Duplication | HIGH | spec.md:L120-134 | Two similar requirements ... | Merge phrasing; keep clearer version |
+
+(Add one row per finding; generate stable IDs prefixed by category initial.)
+
+**Coverage Summary Table:**
+
+| Requirement Key | Has Task? | Task IDs | Notes |
+|-----------------|-----------|----------|-------|
+
+**Constitution Alignment Issues:** (if any)
+
+**Unmapped Tasks:** (if any)
+
+**Metrics:**
+
+- Total Requirements
+- Total Tasks
+- Coverage % (requirements with >=1 task)
+- Ambiguity Count
+- Duplication Count
+- Critical Issues Count
+
+### 7. Provide Next Actions
+
+At end of report, output a concise Next Actions block:
+
+- If CRITICAL issues exist: Recommend resolving before `/speckit.implement`
+- If only LOW/MEDIUM: User may proceed, but provide improvement suggestions
+- Provide explicit command suggestions: e.g., "Run /speckit.specify with refinement", "Run /speckit.plan to adjust architecture", "Manually edit tasks.md to add coverage for 'performance-metrics'"
+
+### 8. Offer Remediation
+
+Ask the user: "Would you like me to suggest concrete remediation edits for the top N issues?" (Do NOT apply them automatically.)
+
+## Operating Principles
+
+### Context Efficiency
+
+- **Minimal high-signal tokens**: Focus on actionable findings, not exhaustive documentation
+- **Progressive disclosure**: Load artifacts incrementally; don't dump all content into analysis
+- **Token-efficient output**: Limit findings table to 50 rows; summarize overflow
+- **Deterministic results**: Rerunning without changes should produce consistent IDs and counts
+
+### Analysis Guidelines
+
+- **NEVER modify files** (this is read-only analysis)
+- **NEVER hallucinate missing sections** (if absent, report them accurately)
+- **Prioritize constitution violations** (these are always CRITICAL)
+- **Use examples over exhaustive rules** (cite specific instances, not generic patterns)
+- **Report zero issues gracefully** (emit success report with coverage statistics)

+description: Generate a custom checklist for the current feature based on user requirements.
+---
+
+## Checklist Purpose: "Unit Tests for English"
+
+**CRITICAL CONCEPT**: Checklists are **UNIT TESTS FOR REQUIREMENTS WRITING** - they validate the quality, clarity, and completeness of requirements in a given domain.
+
+**NOT for verification/testing**:
+
+- ❌ NOT "Verify the button clicks correctly"
+- ❌ NOT "Test error handling works"
+- ❌ NOT "Confirm the API returns 200"
+- ❌ NOT checking if code/implementation matches the spec
+
+**FOR requirements quality validation**:
+
+- ✅ "Are visual hierarchy requirements defined for all card types?" (completeness)
+- ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
+- ✅ "Are hover state requirements consistent across all interactive elements?" (consistency)
+- ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage)
+- ✅ "Does the spec define what happens when logo image fails to load?" (edge cases)
+
+**Metaphor**: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Execution Steps
+
+1. **Setup**: Run `.specify/scripts/bash/check-prerequisites.sh --json` from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS list.
+   - All file paths must be absolute.
+   - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Clarify intent (dynamic)**: Derive up to THREE initial contextual clarifying questions (no pre-baked catalog). They MUST:
+   - Be generated from the user's phrasing + extracted signals from spec/plan/tasks
+   - Only ask about information that materially changes checklist content
+   - Be skipped individually if already unambiguous in `$ARGUMENTS`
+   - Prefer precision over breadth
+
+   Generation algorithm:
+   1. Extract signals: feature domain keywords (e.g., auth, latency, UX, API), risk indicators ("critical", "must", "compliance"), stakeholder hints ("QA", "review", "security team"), and explicit deliverables ("a11y", "rollback", "contracts").
+   2. Cluster signals into candidate focus areas (max 4) ranked by relevance.
+   3. Identify probable audience & timing (author, reviewer, QA, release) if not explicit.
+   4. Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries, measurable acceptance criteria.
+   5. Formulate questions chosen from these archetypes:
+      - Scope refinement (e.g., "Should this include integration touchpoints with X and Y or stay limited to local module correctness?")
+      - Risk prioritization (e.g., "Which of these potential risk areas should receive mandatory gating checks?")
+      - Depth calibration (e.g., "Is this a lightweight pre-commit sanity list or a formal release gate?")
+      - Audience framing (e.g., "Will this be used by the author only or peers during PR review?")
+      - Boundary exclusion (e.g., "Should we explicitly exclude performance tuning items this round?")
+      - Scenario class gap (e.g., "No recovery flows detected—are rollback / partial failure paths in scope?")
+
+   Question formatting rules:
+   - If presenting options, generate a compact table with columns: Option | Candidate | Why It Matters
+   - Limit to A–E options maximum; omit table if a free-form answer is clearer
+   - Never ask the user to restate what they already said
+   - Avoid speculative categories (no hallucination). If uncertain, ask explicitly: "Confirm whether X belongs in scope."
+
+   Defaults when interaction impossible:
+   - Depth: Standard
+   - Audience: Reviewer (PR) if code-related; Author otherwise
+   - Focus: Top 2 relevance clusters
+
+   Output the questions (label Q1/Q2/Q3). After answers: if ≥2 scenario classes (Alternate / Exception / Recovery / Non-Functional domain) remain unclear, you MAY ask up to TWO more targeted follow‑ups (Q4/Q5) with a one-line justification each (e.g., "Unresolved recovery path risk"). Do not exceed five total questions. Skip escalation if user explicitly declines more.
+
+3. **Understand user request**: Combine `$ARGUMENTS` + clarifying answers:
+   - Derive checklist theme (e.g., security, review, deploy, ux)
+   - Consolidate explicit must-have items mentioned by user
+   - Map focus selections to category scaffolding
+   - Infer any missing context from spec/plan/tasks (do NOT hallucinate)
+
+4. **Load feature context**: Read from FEATURE_DIR:
+   - spec.md: Feature requirements and scope
+   - plan.md (if exists): Technical details, dependencies
+   - tasks.md (if exists): Implementation tasks
+
+   **Context Loading Strategy**:
+   - Load only necessary portions relevant to active focus areas (avoid full-file dumping)
+   - Prefer summarizing long sections into concise scenario/requirement bullets
+   - Use progressive disclosure: add follow-on retrieval only if gaps detected
+   - If source docs are large, generate interim summary items instead of embedding raw text
+
+5. **Generate checklist** - Create "Unit Tests for Requirements":
+   - Create `FEATURE_DIR/checklists/` directory if it doesn't exist
+   - Generate unique checklist filename:
+     - Use short, descriptive name based on domain (e.g., `ux.md`, `api.md`, `security.md`)
+     - Format: `[domain].md`
+     - If file exists, append to existing file
+   - Number items sequentially starting from CHK001
+   - Each `/speckit.checklist` run creates a NEW file (never overwrites existing checklists)
+
+   **CORE PRINCIPLE - Test the Requirements, Not the Implementation**:
+   Every checklist item MUST evaluate the REQUIREMENTS THEMSELVES for:
+   - **Completeness**: Are all necessary requirements present?
+   - **Clarity**: Are requirements unambiguous and specific?
+   - **Consistency**: Do requirements align with each other?
+   - **Measurability**: Can requirements be objectively verified?
+   - **Coverage**: Are all scenarios/edge cases addressed?
+
+   **Category Structure** - Group items by requirement quality dimensions:
+   - **Requirement Completeness** (Are all necessary requirements documented?)
+   - **Requirement Clarity** (Are requirements specific and unambiguous?)
+   - **Requirement Consistency** (Do requirements align without conflicts?)
+   - **Acceptance Criteria Quality** (Are success criteria measurable?)
+   - **Scenario Coverage** (Are all flows/cases addressed?)
+   - **Edge Case Coverage** (Are boundary conditions defined?)
+   - **Non-Functional Requirements** (Performance, Security, Accessibility, etc. - are they specified?)
+   - **Dependencies & Assumptions** (Are they documented and validated?)
+   - **Ambiguities & Conflicts** (What needs clarification?)
+
+   **HOW TO WRITE CHECKLIST ITEMS - "Unit Tests for English"**:
+
+   ❌ **WRONG** (Testing implementation):
+   - "Verify landing page displays 3 episode cards"
+   - "Test hover states work on desktop"
+   - "Confirm logo click navigates home"
+
+   ✅ **CORRECT** (Testing requirements quality):
+   - "Are the exact number and layout of featured episodes specified?" [Completeness]
+   - "Is 'prominent display' quantified with specific sizing/positioning?" [Clarity]
+   - "Are hover state requirements consistent across all interactive elements?" [Consistency]
+   - "Are keyboard navigation requirements defined for all interactive UI?" [Coverage]
+   - "Is the fallback behavior specified when logo image fails to load?" [Edge Cases]
+   - "Are loading states defined for asynchronous episode data?" [Completeness]
+   - "Does the spec define visual hierarchy for competing UI elements?" [Clarity]
+
+   **ITEM STRUCTURE**:
+   Each item should follow this pattern:
+   - Question format asking about requirement quality
+   - Focus on what's WRITTEN (or not written) in the spec/plan
+   - Include quality dimension in brackets [Completeness/Clarity/Consistency/etc.]
+   - Reference spec section `[Spec §X.Y]` when checking existing requirements
+   - Use `[Gap]` marker when checking for missing requirements
+
+   **EXAMPLES BY QUALITY DIMENSION**:
+
+   Completeness:
+   - "Are error handling requirements defined for all API failure modes? [Gap]"
+   - "Are accessibility requirements specified for all interactive elements? [Completeness]"
+   - "Are mobile breakpoint requirements defined for responsive layouts? [Gap]"
+
+   Clarity:
+   - "Is 'fast loading' quantified with specific timing thresholds? [Clarity, Spec §NFR-2]"
+   - "Are 'related episodes' selection criteria explicitly defined? [Clarity, Spec §FR-5]"
+   - "Is 'prominent' defined with measurable visual properties? [Ambiguity, Spec §FR-4]"
+
+   Consistency:
+   - "Do navigation requirements align across all pages? [Consistency, Spec §FR-10]"
+   - "Are card component requirements consistent between landing and detail pages? [Consistency]"
+
+   Coverage:
+   - "Are requirements defined for zero-state scenarios (no episodes)? [Coverage, Edge Case]"
+   - "Are concurrent user interaction scenarios addressed? [Coverage, Gap]"
+   - "Are requirements specified for partial data loading failures? [Coverage, Exception Flow]"
+
+   Measurability:
+   - "Are visual hierarchy requirements measurable/testable? [Acceptance Criteria, Spec §FR-1]"
+   - "Can 'balanced visual weight' be objectively verified? [Measurability, Spec §FR-2]"
+
+   **Scenario Classification & Coverage** (Requirements Quality Focus):
+   - Check if requirements exist for: Primary, Alternate, Exception/Error, Recovery, Non-Functional scenarios
+   - For each scenario class, ask: "Are [scenario type] requirements complete, clear, and consistent?"
+   - If scenario class missing: "Are [scenario type] requirements intentionally excluded or missing? [Gap]"
+   - Include resilience/rollback when state mutation occurs: "Are rollback requirements defined for migration failures? [Gap]"
+
+   **Traceability Requirements**:
+   - MINIMUM: ≥80% of items MUST include at least one traceability reference
+   - Each item should reference: spec section `[Spec §X.Y]`, or use markers: `[Gap]`, `[Ambiguity]`, `[Conflict]`, `[Assumption]`
+   - If no ID system exists: "Is a requirement & acceptance criteria ID scheme established? [Traceability]"
+
+   **Surface & Resolve Issues** (Requirements Quality Problems):
+   Ask questions about the requirements themselves:
+   - Ambiguities: "Is the term 'fast' quantified with specific metrics? [Ambiguity, Spec §NFR-1]"
+   - Conflicts: "Do navigation requirements conflict between §FR-10 and §FR-10a? [Conflict]"
+   - Assumptions: "Is the assumption of 'always available podcast API' validated? [Assumption]"
+   - Dependencies: "Are external podcast API requirements documented? [Dependency, Gap]"
+   - Missing definitions: "Is 'visual hierarchy' defined with measurable criteria? [Gap]"
+
+   **Content Consolidation**:
+   - Soft cap: If raw candidate items > 40, prioritize by risk/impact
+   - Merge near-duplicates checking the same requirement aspect
+   - If >5 low-impact edge cases, create one item: "Are edge cases X, Y, Z addressed in requirements? [Coverage]"
+
+   **🚫 ABSOLUTELY PROHIBITED** - These make it an implementation test, not a requirements test:
+   - ❌ Any item starting with "Verify", "Test", "Confirm", "Check" + implementation behavior
+   - ❌ References to code execution, user actions, system behavior
+   - ❌ "Displays correctly", "works properly", "functions as expected"
+   - ❌ "Click", "navigate", "render", "load", "execute"
+   - ❌ Test cases, test plans, QA procedures
+   - ❌ Implementation details (frameworks, APIs, algorithms)
+
+   **✅ REQUIRED PATTERNS** - These test requirements quality:
+   - ✅ "Are [requirement type] defined/specified/documented for [scenario]?"
+   - ✅ "Is [vague term] quantified/clarified with specific criteria?"
+   - ✅ "Are requirements consistent between [section A] and [section B]?"
+   - ✅ "Can [requirement] be objectively measured/verified?"
+   - ✅ "Are [edge cases/scenarios] addressed in requirements?"
+   - ✅ "Does the spec define [missing aspect]?"
+
+6. **Structure Reference**: Generate the checklist following the canonical template in `.specify/templates/checklist-template.md` for title, meta section, category headings, and ID formatting. If template is unavailable, use: H1 title, purpose/created meta lines, `##` category sections containing `- [ ] CHK### <requirement item>` lines with globally incrementing IDs starting at CHK001.
+
+7. **Report**: Output full path to created checklist, item count, and remind user that each run creates a new file. Summarize:
+   - Focus areas selected
+   - Depth level
+   - Actor/timing
+   - Any explicit user-specified must-have items incorporated
+
+**Important**: Each `/speckit.checklist` command invocation creates a checklist file using short, descriptive names unless file already exists. This allows:
+
+- Multiple checklists of different types (e.g., `ux.md`, `test.md`, `security.md`)
+- Simple, memorable filenames that indicate checklist purpose
+- Easy identification and navigation in the `checklists/` folder
+
+To avoid clutter, use descriptive types and clean up obsolete checklists when done.
+
+## Example Checklist Types & Sample Items
+
+**UX Requirements Quality:** `ux.md`
+
+Sample items (testing the requirements, NOT the implementation):
+
+- "Are visual hierarchy requirements defined with measurable criteria? [Clarity, Spec §FR-1]"
+- "Is the number and positioning of UI elements explicitly specified? [Completeness, Spec §FR-1]"
+- "Are interaction state requirements (hover, focus, active) consistently defined? [Consistency]"
+- "Are accessibility requirements specified for all interactive elements? [Coverage, Gap]"
+- "Is fallback behavior defined when images fail to load? [Edge Case, Gap]"
+- "Can 'prominent display' be objectively measured? [Measurability, Spec §FR-4]"
+
+**API Requirements Quality:** `api.md`
+
+Sample items:
+
+- "Are error response formats specified for all failure scenarios? [Completeness]"
+- "Are rate limiting requirements quantified with specific thresholds? [Clarity]"
+- "Are authentication requirements consistent across all endpoints? [Consistency]"
+- "Are retry/timeout requirements defined for external dependencies? [Coverage, Gap]"
+- "Is versioning strategy documented in requirements? [Gap]"
+
+**Performance Requirements Quality:** `performance.md`
+
+Sample items:
+
+- "Are performance requirements quantified with specific metrics? [Clarity]"
+- "Are performance targets defined for all critical user journeys? [Coverage]"
+- "Are performance requirements under different load conditions specified? [Completeness]"
+- "Can performance requirements be objectively measured? [Measurability]"
+- "Are degradation requirements defined for high-load scenarios? [Edge Case, Gap]"
+
+**Security Requirements Quality:** `security.md`
+
+Sample items:
+
+- "Are authentication requirements specified for all protected resources? [Coverage]"
+- "Are data protection requirements defined for sensitive information? [Completeness]"
+- "Is the threat model documented and requirements aligned to it? [Traceability]"
+- "Are security requirements consistent with compliance obligations? [Consistency]"
+- "Are security failure/breach response requirements defined? [Gap, Exception Flow]"
+
+## Anti-Examples: What NOT To Do
+
+**❌ WRONG - These test implementation, not requirements:**
+
+```markdown
+- [ ] CHK001 - Verify landing page displays 3 episode cards [Spec §FR-001]
+- [ ] CHK002 - Test hover states work correctly on desktop [Spec §FR-003]
+- [ ] CHK003 - Confirm logo click navigates to home page [Spec §FR-010]
+- [ ] CHK004 - Check that related episodes section shows 3-5 items [Spec §FR-005]
+```
+
+**✅ CORRECT - These test requirements quality:**
+
+```markdown
+- [ ] CHK001 - Are the number and layout of featured episodes explicitly specified? [Completeness, Spec §FR-001]
+- [ ] CHK002 - Are hover state requirements consistently defined for all interactive elements? [Consistency, Spec §FR-003]
+- [ ] CHK003 - Are navigation requirements clear for all clickable brand elements? [Clarity, Spec §FR-010]
+- [ ] CHK004 - Is the selection criteria for related episodes documented? [Gap, Spec §FR-005]
+- [ ] CHK005 - Are loading state requirements defined for asynchronous episode data? [Gap]
+- [ ] CHK006 - Can "visual hierarchy" requirements be objectively measured? [Measurability, Spec §FR-001]
+```
+
+**Key Differences:**
+
+- Wrong: Tests if the system works correctly
+- Correct: Tests if the requirements are written correctly
+- Wrong: Verification of behavior
+- Correct: Validation of requirement quality
+- Wrong: "Does it do X?"
+- Correct: "Is X clearly specified?"

+    prompt: Create a plan for the spec. I am building with...
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+Goal: Detect and reduce ambiguity or missing decision points in the active feature specification and record the clarifications directly in the spec file.
+
+Note: This clarification workflow is expected to run (and be completed) BEFORE invoking `/speckit.plan`. If the user explicitly states they are skipping clarification (e.g., exploratory spike), you may proceed, but must warn that downstream rework risk increases.
+
+Execution steps:
+
+1. Run `.specify/scripts/bash/check-prerequisites.sh --json --paths-only` from repo root **once** (combined `--json --paths-only` mode / `-Json -PathsOnly`). Parse minimal JSON payload fields:
+   - `FEATURE_DIR`
+   - `FEATURE_SPEC`
+   - (Optionally capture `IMPL_PLAN`, `TASKS` for future chained flows.)
+   - If JSON parsing fails, abort and instruct user to re-run `/speckit.specify` or verify feature branch environment.
+   - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. Load the current spec file. Perform a structured ambiguity & coverage scan using this taxonomy. For each category, mark status: Clear / Partial / Missing. Produce an internal coverage map used for prioritization (do not output raw map unless no questions will be asked).
+
+   Functional Scope & Behavior:
+   - Core user goals & success criteria
+   - Explicit out-of-scope declarations
+   - User roles / personas differentiation
+
+   Domain & Data Model:
+   - Entities, attributes, relationships
+   - Identity & uniqueness rules
+   - Lifecycle/state transitions
+   - Data volume / scale assumptions
+
+   Interaction & UX Flow:
+   - Critical user journeys / sequences
+   - Error/empty/loading states
+   - Accessibility or localization notes
+
+   Non-Functional Quality Attributes:
+   - Performance (latency, throughput targets)
+   - Scalability (horizontal/vertical, limits)
+   - Reliability & availability (uptime, recovery expectations)
+   - Observability (logging, metrics, tracing signals)
+   - Security & privacy (authN/Z, data protection, threat assumptions)
+   - Compliance / regulatory constraints (if any)
+
+   Integration & External Dependencies:
+   - External services/APIs and failure modes
+   - Data import/export formats
+   - Protocol/versioning assumptions
+
+   Edge Cases & Failure Handling:
+   - Negative scenarios
+   - Rate limiting / throttling
+   - Conflict resolution (e.g., concurrent edits)
+
+   Constraints & Tradeoffs:
+   - Technical constraints (language, storage, hosting)
+   - Explicit tradeoffs or rejected alternatives
+
+   Terminology & Consistency:
+   - Canonical glossary terms
+   - Avoided synonyms / deprecated terms
+
+   Completion Signals:
+   - Acceptance criteria testability
+   - Measurable Definition of Done style indicators
+
+   Misc / Placeholders:
+   - TODO markers / unresolved decisions
+   - Ambiguous adjectives ("robust", "intuitive") lacking quantification
+
+   For each category with Partial or Missing status, add a candidate question opportunity unless:
+   - Clarification would not materially change implementation or validation strategy
+   - Information is better deferred to planning phase (note internally)
+
+3. Generate (internally) a prioritized queue of candidate clarification questions (maximum 5). Do NOT output them all at once. Apply these constraints:
+    - Maximum of 10 total questions across the whole session.
+    - Each question must be answerable with EITHER:
+       - A short multiple‑choice selection (2–5 distinct, mutually exclusive options), OR
+       - A one-word / short‑phrase answer (explicitly constrain: "Answer in <=5 words").
+    - Only include questions whose answers materially impact architecture, data modeling, task decomposition, test design, UX behavior, operational readiness, or compliance validation.
+    - Ensure category coverage balance: attempt to cover the highest impact unresolved categories first; avoid asking two low-impact questions when a single high-impact area (e.g., security posture) is unresolved.
+    - Exclude questions already answered, trivial stylistic preferences, or plan-level execution details (unless blocking correctness).
+    - Favor clarifications that reduce downstream rework risk or prevent misaligned acceptance tests.
+    - If more than 5 categories remain unresolved, select the top 5 by (Impact * Uncertainty) heuristic.
+
+4. Sequential questioning loop (interactive):
+    - Present EXACTLY ONE question at a time.
+    - For multiple‑choice questions:
+       - **Analyze all options** and determine the **most suitable option** based on:
+          - Best practices for the project type
+          - Common patterns in similar implementations
+          - Risk reduction (security, performance, maintainability)
+          - Alignment with any explicit project goals or constraints visible in the spec
+       - Present your **recommended option prominently** at the top with clear reasoning (1-2 sentences explaining why this is the best choice).
+       - Format as: `**Recommended:** Option [X] - <reasoning>`
+       - Then render all options as a Markdown table:
+
+       | Option | Description |
+       |--------|-------------|
+       | A | <Option A description> |
+       | B | <Option B description> |
+       | C | <Option C description> (add D/E as needed up to 5) |
+       | Short | Provide a different short answer (<=5 words) (Include only if free-form alternative is appropriate) |
+
+       - After the table, add: `You can reply with the option letter (e.g., "A"), accept the recommendation by saying "yes" or "recommended", or provide your own short answer.`
+    - For short‑answer style (no meaningful discrete options):
+       - Provide your **suggested answer** based on best practices and context.
+       - Format as: `**Suggested:** <your proposed answer> - <brief reasoning>`
+       - Then output: `Format: Short answer (<=5 words). You can accept the suggestion by saying "yes" or "suggested", or provide your own answer.`
+    - After the user answers:
+       - If the user replies with "yes", "recommended", or "suggested", use your previously stated recommendation/suggestion as the answer.
+       - Otherwise, validate the answer maps to one option or fits the <=5 word constraint.
+       - If ambiguous, ask for a quick disambiguation (count still belongs to same question; do not advance).
+       - Once satisfactory, record it in working memory (do not yet write to disk) and move to the next queued question.
+    - Stop asking further questions when:
+       - All critical ambiguities resolved early (remaining queued items become unnecessary), OR
+       - User signals completion ("done", "good", "no more"), OR
+       - You reach 5 asked questions.
+    - Never reveal future queued questions in advance.
+    - If no valid questions exist at start, immediately report no critical ambiguities.
+
+5. Integration after EACH accepted answer (incremental update approach):
+    - Maintain in-memory representation of the spec (loaded once at start) plus the raw file contents.
+    - For the first integrated answer in this session:
+       - Ensure a `## Clarifications` section exists (create it just after the highest-level contextual/overview section per the spec template if missing).
+       - Under it, create (if not present) a `### Session YYYY-MM-DD` subheading for today.
+    - Append a bullet line immediately after acceptance: `- Q: <question> → A: <final answer>`.
+    - Then immediately apply the clarification to the most appropriate section(s):
+       - Functional ambiguity → Update or add a bullet in Functional Requirements.
+       - User interaction / actor distinction → Update User Stories or Actors subsection (if present) with clarified role, constraint, or scenario.
+       - Data shape / entities → Update Data Model (add fields, types, relationships) preserving ordering; note added constraints succinctly.
+       - Non-functional constraint → Add/modify measurable criteria in Non-Functional / Quality Attributes section (convert vague adjective to metric or explicit target).
+       - Edge case / negative flow → Add a new bullet under Edge Cases / Error Handling (or create such subsection if template provides placeholder for it).
+       - Terminology conflict → Normalize term across spec; retain original only if necessary by adding `(formerly referred to as "X")` once.
+    - If the clarification invalidates an earlier ambiguous statement, replace that statement instead of duplicating; leave no obsolete contradictory text.
+    - Save the spec file AFTER each integration to minimize risk of context loss (atomic overwrite).
+    - Preserve formatting: do not reorder unrelated sections; keep heading hierarchy intact.
+    - Keep each inserted clarification minimal and testable (avoid narrative drift).
+
+6. Validation (performed after EACH write plus final pass):
+   - Clarifications session contains exactly one bullet per accepted answer (no duplicates).
+   - Total asked (accepted) questions ≤ 5.
+   - Updated sections contain no lingering vague placeholders the new answer was meant to resolve.
+   - No contradictory earlier statement remains (scan for now-invalid alternative choices removed).
+   - Markdown structure valid; only allowed new headings: `## Clarifications`, `### Session YYYY-MM-DD`.
+   - Terminology consistency: same canonical term used across all updated sections.
+
+7. Write the updated spec back to `FEATURE_SPEC`.
+
+8. Report completion (after questioning loop ends or early termination):
+   - Number of questions asked & answered.
+   - Path to updated spec.
+   - Sections touched (list names).
+   - Coverage summary table listing each taxonomy category with Status: Resolved (was Partial/Missing and addressed), Deferred (exceeds question quota or better suited for planning), Clear (already sufficient), Outstanding (still Partial/Missing but low impact).
+   - If any Outstanding or Deferred remain, recommend whether to proceed to `/speckit.plan` or run `/speckit.clarify` again later post-plan.
+   - Suggested next command.
+
+Behavior rules:
+
+- If no meaningful ambiguities found (or all potential questions would be low-impact), respond: "No critical ambiguities detected worth formal clarification." and suggest proceeding.
+- If spec file missing, instruct user to run `/speckit.specify` first (do not create a new spec here).
+- Never exceed 5 total asked questions (clarification retries for a single question do not count as new questions).
+- Avoid speculative tech stack questions unless the absence blocks functional clarity.
+- Respect user early termination signals ("stop", "done", "proceed").
+- If no questions asked due to full coverage, output a compact coverage summary (all categories Clear) then suggest advancing.
+- If quota reached with unresolved high-impact categories remaining, explicitly flag them under Deferred with rationale.

+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+You are updating the project constitution at `.specify/memory/constitution.md`. This file is a TEMPLATE containing placeholder tokens in square brackets (e.g. `[PROJECT_NAME]`, `[PRINCIPLE_1_NAME]`). Your job is to (a) collect/derive concrete values, (b) fill the template precisely, and (c) propagate any amendments across dependent artifacts.
+
+Follow this execution flow:
+
+1. Load the existing constitution template at `.specify/memory/constitution.md`.
+   - Identify every placeholder token of the form `[ALL_CAPS_IDENTIFIER]`.
+   **IMPORTANT**: The user might require less or more principles than the ones used in the template. If a number is specified, respect that - follow the general template. You will update the doc accordingly.
+
+2. Collect/derive values for placeholders:
+   - If user input (conversation) supplies a value, use it.
+   - Otherwise infer from existing repo context (README, docs, prior constitution versions if embedded).
+   - For governance dates: `RATIFICATION_DATE` is the original adoption date (if unknown ask or mark TODO), `LAST_AMENDED_DATE` is today if changes are made, otherwise keep previous.
+   - `CONSTITUTION_VERSION` must increment according to semantic versioning rules:
+     - MAJOR: Backward incompatible governance/principle removals or redefinitions.
+     - MINOR: New principle/section added or materially expanded guidance.
+     - PATCH: Clarifications, wording, typo fixes, non-semantic refinements.
+   - If version bump type ambiguous, propose reasoning before finalizing.
+
+3. Draft the updated constitution content:
+   - Replace every placeholder with concrete text (no bracketed tokens left except intentionally retained template slots that the project has chosen not to define yet—explicitly justify any left).
+   - Preserve heading hierarchy and comments can be removed once replaced unless they still add clarifying guidance.
+   - Ensure each Principle section: succinct name line, paragraph (or bullet list) capturing non‑negotiable rules, explicit rationale if not obvious.
+   - Ensure Governance section lists amendment procedure, versioning policy, and compliance review expectations.
+
+4. Consistency propagation checklist (convert prior checklist into active validations):
+   - Read `.specify/templates/plan-template.md` and ensure any "Constitution Check" or rules align with updated principles.
+   - Read `.specify/templates/spec-template.md` for scope/requirements alignment—update if constitution adds/removes mandatory sections or constraints.
+   - Read `.specify/templates/tasks-template.md` and ensure task categorization reflects new or removed principle-driven task types (e.g., observability, versioning, testing discipline).
+   - Read each command file in `.specify/templates/commands/*.md` (including this one) to verify no outdated references (agent-specific names like CLAUDE only) remain when generic guidance is required.
+   - Read any runtime guidance docs (e.g., `README.md`, `docs/quickstart.md`, or agent-specific guidance files if present). Update references to principles changed.
+
+5. Produce a Sync Impact Report (prepend as an HTML comment at top of the constitution file after update):
+   - Version change: old → new
+   - List of modified principles (old title → new title if renamed)
+   - Added sections
+   - Removed sections
+   - Templates requiring updates (✅ updated / ⚠ pending) with file paths
+   - Follow-up TODOs if any placeholders intentionally deferred.
+
+6. Validation before final output:
+   - No remaining unexplained bracket tokens.
+   - Version line matches report.
+   - Dates ISO format YYYY-MM-DD.
+   - Principles are declarative, testable, and free of vague language ("should" → replace with MUST/SHOULD rationale where appropriate).
+
+7. Write the completed constitution back to `.specify/memory/constitution.md` (overwrite).
+
+8. Output a final summary to the user with:
+   - New version and bump rationale.
+   - Any files flagged for manual follow-up.
+   - Suggested commit message (e.g., `docs: amend constitution to vX.Y.Z (principle additions + governance update)`).
+
+Formatting & Style Requirements:
+
+- Use Markdown headings exactly as in the template (do not demote/promote levels).
+- Wrap long rationale lines to keep readability (<100 chars ideally) but do not hard enforce with awkward breaks.
+- Keep a single blank line between sections.
+- Avoid trailing whitespace.
+
+If the user supplies partial updates (e.g., only one principle revision), still perform validation and version decision steps.
+
+If critical info missing (e.g., ratification date truly unknown), insert `TODO(<FIELD_NAME>): explanation` and include in the Sync Impact Report under deferred items.
+
+Do not create a new template; always operate on the existing `.specify/memory/constitution.md` file.

+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+1. Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Check checklists status** (if FEATURE_DIR/checklists/ exists):
+   - Scan all checklist files in the checklists/ directory
+   - For each checklist, count:
+     - Total items: All lines matching `- [ ]` or `- [X]` or `- [x]`
+     - Completed items: Lines matching `- [X]` or `- [x]`
+     - Incomplete items: Lines matching `- [ ]`
+   - Create a status table:
+
+     ```text
+     | Checklist | Total | Completed | Incomplete | Status |
+     |-----------|-------|-----------|------------|--------|
+     | ux.md     | 12    | 12        | 0          | ✓ PASS |
+     | test.md   | 8     | 5         | 3          | ✗ FAIL |
+     | security.md | 6   | 6         | 0          | ✓ PASS |
+     ```
+
+   - Calculate overall status:
+     - **PASS**: All checklists have 0 incomplete items
+     - **FAIL**: One or more checklists have incomplete items
+
+   - **If any checklist is incomplete**:
+     - Display the table with incomplete item counts
+     - **STOP** and ask: "Some checklists are incomplete. Do you want to proceed with implementation anyway? (yes/no)"
+     - Wait for user response before continuing
+     - If user says "no" or "wait" or "stop", halt execution
+     - If user says "yes" or "proceed" or "continue", proceed to step 3
+
+   - **If all checklists are complete**:
+     - Display the table showing all checklists passed
+     - Automatically proceed to step 3
+
+3. Load and analyze the implementation context:
+   - **REQUIRED**: Read tasks.md for the complete task list and execution plan
+   - **REQUIRED**: Read plan.md for tech stack, architecture, and file structure
+   - **IF EXISTS**: Read data-model.md for entities and relationships
+   - **IF EXISTS**: Read contracts/ for API specifications and test requirements
+   - **IF EXISTS**: Read research.md for technical decisions and constraints
+   - **IF EXISTS**: Read quickstart.md for integration scenarios
+
+4. **Project Setup Verification**:
+   - **REQUIRED**: Create/verify ignore files based on actual project setup:
+
+   **Detection & Creation Logic**:
+   - Check if the following command succeeds to determine if the repository is a git repo (create/verify .gitignore if so):
+
+     ```sh
+     git rev-parse --git-dir 2>/dev/null
+     ```
+
+   - Check if Dockerfile* exists or Docker in plan.md → create/verify .dockerignore
+   - Check if .eslintrc* exists → create/verify .eslintignore
+   - Check if eslint.config.* exists → ensure the config's `ignores` entries cover required patterns
+   - Check if .prettierrc* exists → create/verify .prettierignore
+   - Check if .npmrc or package.json exists → create/verify .npmignore (if publishing)
+   - Check if terraform files (*.tf) exist → create/verify .terraformignore
+   - Check if .helmignore needed (helm charts present) → create/verify .helmignore
+
+   **If ignore file already exists**: Verify it contains essential patterns, append missing critical patterns only
+   **If ignore file missing**: Create with full pattern set for detected technology
+
+   **Common Patterns by Technology** (from plan.md tech stack):
+   - **Node.js/JavaScript/TypeScript**: `node_modules/`, `dist/`, `build/`, `*.log`, `.env*`
+   - **Python**: `__pycache__/`, `*.pyc`, `.venv/`, `venv/`, `dist/`, `*.egg-info/`
+   - **Java**: `target/`, `*.class`, `*.jar`, `.gradle/`, `build/`
+   - **C#/.NET**: `bin/`, `obj/`, `*.user`, `*.suo`, `packages/`
+   - **Go**: `*.exe`, `*.test`, `vendor/`, `*.out`
+   - **Ruby**: `.bundle/`, `log/`, `tmp/`, `*.gem`, `vendor/bundle/`
+   - **PHP**: `vendor/`, `*.log`, `*.cache`, `*.env`
+   - **Rust**: `target/`, `debug/`, `release/`, `*.rs.bk`, `*.rlib`, `*.prof*`, `.idea/`, `*.log`, `.env*`
+   - **Kotlin**: `build/`, `out/`, `.gradle/`, `.idea/`, `*.class`, `*.jar`, `*.iml`, `*.log`, `.env*`
+   - **C++**: `build/`, `bin/`, `obj/`, `out/`, `*.o`, `*.so`, `*.a`, `*.exe`, `*.dll`, `.idea/`, `*.log`, `.env*`
+   - **C**: `build/`, `bin/`, `obj/`, `out/`, `*.o`, `*.a`, `*.so`, `*.exe`, `Makefile`, `config.log`, `.idea/`, `*.log`, `.env*`
+   - **Swift**: `.build/`, `DerivedData/`, `*.swiftpm/`, `Packages/`
+   - **R**: `.Rproj.user/`, `.Rhistory`, `.RData`, `.Ruserdata`, `*.Rproj`, `packrat/`, `renv/`
+   - **Universal**: `.DS_Store`, `Thumbs.db`, `*.tmp`, `*.swp`, `.vscode/`, `.idea/`
+
+   **Tool-Specific Patterns**:
+   - **Docker**: `node_modules/`, `.git/`, `Dockerfile*`, `.dockerignore`, `*.log*`, `.env*`, `coverage/`
+   - **ESLint**: `node_modules/`, `dist/`, `build/`, `coverage/`, `*.min.js`
+   - **Prettier**: `node_modules/`, `dist/`, `build/`, `coverage/`, `package-lock.json`, `yarn.lock`, `pnpm-lock.yaml`
+   - **Terraform**: `.terraform/`, `*.tfstate*`, `*.tfvars`, `.terraform.lock.hcl`
+   - **Kubernetes/k8s**: `*.secret.yaml`, `secrets/`, `.kube/`, `kubeconfig*`, `*.key`, `*.crt`
+
+5. Parse tasks.md structure and extract:
+   - **Task phases**: Setup, Tests, Core, Integration, Polish
+   - **Task dependencies**: Sequential vs parallel execution rules
+   - **Task details**: ID, description, file paths, parallel markers [P]
+   - **Execution flow**: Order and dependency requirements
+
+6. Execute implementation following the task plan:
+   - **Phase-by-phase execution**: Complete each phase before moving to the next
+   - **Respect dependencies**: Run sequential tasks in order, parallel tasks [P] can run together  
+   - **Follow TDD approach**: Execute test tasks before their corresponding implementation tasks
+   - **File-based coordination**: Tasks affecting the same files must run sequentially
+   - **Validation checkpoints**: Verify each phase completion before proceeding
+
+7. Implementation execution rules:
+   - **Setup first**: Initialize project structure, dependencies, configuration
+   - **Tests before code**: If you need to write tests for contracts, entities, and integration scenarios
+   - **Core development**: Implement models, services, CLI commands, endpoints
+   - **Integration work**: Database connections, middleware, logging, external services
+   - **Polish and validation**: Unit tests, performance optimization, documentation
+
+8. Progress tracking and error handling:
+   - Report progress after each completed task
+   - Halt execution if any non-parallel task fails
+   - For parallel tasks [P], continue with successful tasks, report failed ones
+   - Provide clear error messages with context for debugging
+   - Suggest next steps if implementation cannot proceed
+   - **IMPORTANT** For completed tasks, make sure to mark the task off as [X] in the tasks file.
+
+9. Completion validation:
+   - Verify all required tasks are completed
+   - Check that implemented features match the original specification
+   - Validate that tests pass and coverage meets requirements
+   - Confirm the implementation follows the technical plan
+   - Report final status with summary of completed work
+
+Note: This command assumes a complete task breakdown exists in tasks.md. If tasks are incomplete or missing, suggest running `/speckit.tasks` first to regenerate the task list.

+
+## Outline
+
+1. **Setup**: Run `.specify/scripts/bash/setup-plan.sh --json` from repo root and parse JSON for FEATURE_SPEC, IMPL_PLAN, SPECS_DIR, BRANCH. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Load context**: Read FEATURE_SPEC and `.specify/memory/constitution.md`. Load IMPL_PLAN template (already copied).
+
+3. **Execute plan workflow**: Follow the structure in IMPL_PLAN template to:
+   - Fill Technical Context (mark unknowns as "NEEDS CLARIFICATION")
+   - Fill Constitution Check section from constitution
+   - Evaluate gates (ERROR if violations unjustified)
+   - Phase 0: Generate research.md (resolve all NEEDS CLARIFICATION)
+   - Phase 1: Generate data-model.md, contracts/, quickstart.md
+   - Phase 1: Update agent context by running the agent script
+   - Re-evaluate Constitution Check post-design
+
+4. **Stop and report**: Command ends after Phase 2 planning. Report branch, IMPL_PLAN path, and generated artifacts.
+
+## Phases
+
+### Phase 0: Outline & Research
+
+1. **Extract unknowns from Technical Context** above:
+   - For each NEEDS CLARIFICATION → research task
+   - For each dependency → best practices task
+   - For each integration → patterns task
+
+2. **Generate and dispatch research agents**:
+
+   ```text
+   For each unknown in Technical Context:
+     Task: "Research {unknown} for {feature context}"
+   For each technology choice:
+     Task: "Find best practices for {tech} in {domain}"
+   ```
+
+3. **Consolidate findings** in `research.md` using format:
+   - Decision: [what was chosen]
+   - Rationale: [why chosen]
+   - Alternatives considered: [what else evaluated]
+
+**Output**: research.md with all NEEDS CLARIFICATION resolved
+
+### Phase 1: Design & Contracts
+
+**Prerequisites:** `research.md` complete
+
+1. **Extract entities from feature spec** → `data-model.md`:
+   - Entity name, fields, relationships
+   - Validation rules from requirements
+   - State transitions if applicable
+
+2. **Generate API contracts** from functional requirements:
+   - For each user action → endpoint
+   - Use standard REST/GraphQL patterns
+   - Output OpenAPI/GraphQL schema to `/contracts/`
+
+3. **Agent context update**:
+   - Run `.specify/scripts/bash/update-agent-context.sh kilocode`
+   - These scripts detect which AI agent is in use
+   - Update the appropriate agent-specific context file
+   - Add only new technology from current plan
+   - Preserve manual additions between markers
+
+**Output**: data-model.md, /contracts/*, quickstart.md, agent-specific file
+
+## Key rules

+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+The text the user typed after `/speckit.specify` in the triggering message **is** the feature description. Assume you always have it available in this conversation even if `$ARGUMENTS` appears literally below. Do not ask the user to repeat it unless they provided an empty command.
+
+Given that feature description, do this:
+
+1. **Generate a concise short name** (2-4 words) for the branch:
+   - Analyze the feature description and extract the most meaningful keywords
+   - Create a 2-4 word short name that captures the essence of the feature
+   - Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
+   - Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
+   - Keep it concise but descriptive enough to understand the feature at a glance
+   - Examples:
+     - "I want to add user authentication" → "user-auth"
+     - "Implement OAuth2 integration for the API" → "oauth2-api-integration"
+     - "Create a dashboard for analytics" → "analytics-dashboard"
+     - "Fix payment processing timeout bug" → "fix-payment-timeout"
+
+2. **Check for existing branches before creating new one**:
+
+   a. First, fetch all remote branches to ensure we have the latest information:
+
+      ```bash
+      git fetch --all --prune
+      ```
+
+   b. Find the highest feature number across all sources for the short-name:
+      - Remote branches: `git ls-remote --heads origin | grep -E 'refs/heads/[0-9]+-<short-name>$'`
+      - Local branches: `git branch | grep -E '^[* ]*[0-9]+-<short-name>$'`
+      - Specs directories: Check for directories matching `specs/[0-9]+-<short-name>`
+
+   c. Determine the next available number:
+      - Extract all numbers from all three sources
+      - Find the highest number N
+      - Use N+1 for the new branch number
+
+   d. Run the script `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS"` with the calculated number and short-name:
+      - Pass `--number N+1` and `--short-name "your-short-name"` along with the feature description
+      - Bash example: `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS" --json --number 5 --short-name "user-auth" "Add user authentication"`
+      - PowerShell example: `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS" -Json -Number 5 -ShortName "user-auth" "Add user authentication"`
+
+   **IMPORTANT**:
+   - Check all three sources (remote branches, local branches, specs directories) to find the highest number
+   - Only match branches/directories with the exact short-name pattern
+   - If no existing branches/directories found with this short-name, start with number 1
+   - You must only ever run this script once per feature
+   - The JSON is provided in the terminal as output - always refer to it to get the actual content you're looking for
+   - The JSON output will contain BRANCH_NAME and SPEC_FILE paths
+   - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot")
+
+3. Load `.specify/templates/spec-template.md` to understand required sections.
+
+4. Follow this execution flow:
+
+    1. Parse user description from Input
+       If empty: ERROR "No feature description provided"
+    2. Extract key concepts from description
+       Identify: actors, actions, data, constraints
+    3. For unclear aspects:
+       - Make informed guesses based on context and industry standards
+       - Only mark with [NEEDS CLARIFICATION: specific question] if:
+         - The choice significantly impacts feature scope or user experience
+         - Multiple reasonable interpretations exist with different implications
+         - No reasonable default exists
+       - **LIMIT: Maximum 3 [NEEDS CLARIFICATION] markers total**
+       - Prioritize clarifications by impact: scope > security/privacy > user experience > technical details
+    4. Fill User Scenarios & Testing section
+       If no clear user flow: ERROR "Cannot determine user scenarios"
+    5. Generate Functional Requirements
+       Each requirement must be testable
+       Use reasonable defaults for unspecified details (document assumptions in Assumptions section)
+    6. Define Success Criteria
+       Create measurable, technology-agnostic outcomes
+       Include both quantitative metrics (time, performance, volume) and qualitative measures (user satisfaction, task completion)
+       Each criterion must be verifiable without implementation details
+    7. Identify Key Entities (if data involved)
+    8. Return: SUCCESS (spec ready for planning)
+
+5. Write the specification to SPEC_FILE using the template structure, replacing placeholders with concrete details derived from the feature description (arguments) while preserving section order and headings.
+
+6. **Specification Quality Validation**: After writing the initial spec, validate it against quality criteria:
+
+   a. **Create Spec Quality Checklist**: Generate a checklist file at `FEATURE_DIR/checklists/requirements.md` using the checklist template structure with these validation items:
+
+      ```markdown
+      # Specification Quality Checklist: [FEATURE NAME]
+      
+      **Purpose**: Validate specification completeness and quality before proceeding to planning
+      **Created**: [DATE]
+      **Feature**: [Link to spec.md]
+      
+      ## Content Quality

+      ## Notes
+      
+      - Items marked incomplete require spec updates before `/speckit.clarify` or `/speckit.plan`
+      ```
+
+   b. **Run Validation Check**: Review the spec against each checklist item:
+      - For each item, determine if it passes or fails
+      - Document specific issues found (quote relevant spec sections)
+
+   c. **Handle Validation Results**:
+
+      - **If all items pass**: Mark checklist complete and proceed to step 6
+
+      - **If items fail (excluding [NEEDS CLARIFICATION])**:
+        1. List the failing items and specific issues
+        2. Update the spec to address each issue
+        3. Re-run validation until all items pass (max 3 iterations)
+        4. If still failing after 3 iterations, document remaining issues in checklist notes and warn user
+
+      - **If [NEEDS CLARIFICATION] markers remain**:
+        1. Extract all [NEEDS CLARIFICATION: ...] markers from the spec
+        2. **LIMIT CHECK**: If more than 3 markers exist, keep only the 3 most critical (by scope/security/UX impact) and make informed guesses for the rest
+        3. For each clarification needed (max 3), present options to user in this format:
+
+           ```markdown
+           ## Question [N]: [Topic]
+           
+           **Context**: [Quote relevant spec section]
+           
+           **What we need to know**: [Specific question from NEEDS CLARIFICATION marker]
+           
+           **Suggested Answers**:
+           
+           | Option | Answer | Implications |
+           |--------|--------|--------------|
+           | A      | [First suggested answer] | [What this means for the feature] |
+           | B      | [Second suggested answer] | [What this means for the feature] |
+           | C      | [Third suggested answer] | [What this means for the feature] |
+           | Custom | Provide your own answer | [Explain how to provide custom input] |
+           
+           **Your choice**: _[Wait for user response]_
+           ```
+
+        4. **CRITICAL - Table Formatting**: Ensure markdown tables are properly formatted:
+           - Use consistent spacing with pipes aligned
+           - Each cell should have spaces around content: `| Content |` not `|Content|`
+           - Header separator must have at least 3 dashes: `|--------|`
+           - Test that the table renders correctly in markdown preview
+        5. Number questions sequentially (Q1, Q2, Q3 - max 3 total)
+        6. Present all questions together before waiting for responses
+        7. Wait for user to respond with their choices for all questions (e.g., "Q1: A, Q2: Custom - [details], Q3: B")
+        8. Update the spec by replacing each [NEEDS CLARIFICATION] marker with the user's selected or provided answer
+        9. Re-run validation after all clarifications are resolved
+
+   d. **Update Checklist**: After each validation iteration, update the checklist file with current pass/fail status
+
+7. Report completion with branch name, spec file path, checklist results, and readiness for the next phase (`/speckit.clarify` or `/speckit.plan`).
+
+**NOTE:** The script creates and checks out the new branch and initializes the spec file before writing.
+
+## General Guidelines
+
+## Quick Guidelines
+
+- Focus on **WHAT** users need and **WHY**.
+- Avoid HOW to implement (no tech stack, APIs, code structure).
+- Written for business stakeholders, not developers.
+- DO NOT create any checklists that are embedded in the spec. That will be a separate command.
+
+### Section Requirements
+
+- **Mandatory sections**: Must be completed for every feature
+- **Optional sections**: Include only when relevant to the feature
+- When a section doesn't apply, remove it entirely (don't leave as "N/A")
+
+### For AI Generation
+
+When creating this spec from a user prompt:
+
+1. **Make informed guesses**: Use context, industry standards, and common patterns to fill gaps
+2. **Document assumptions**: Record reasonable defaults in the Assumptions section
+3. **Limit clarifications**: Maximum 3 [NEEDS CLARIFICATION] markers - use only for critical decisions that:
+   - Significantly impact feature scope or user experience
+   - Have multiple reasonable interpretations with different implications
+   - Lack any reasonable default
+4. **Prioritize clarifications**: scope > security/privacy > user experience > technical details
+5. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
+6. **Common areas needing clarification** (only if no reasonable default exists):
+   - Feature scope and boundaries (include/exclude specific use cases)
+   - User types and permissions (if multiple conflicting interpretations possible)
+   - Security/compliance requirements (when legally/financially significant)
+
+**Examples of reasonable defaults** (don't ask about these):
+
+- Data retention: Industry-standard practices for the domain
+- Performance targets: Standard web/mobile app expectations unless specified
+- Error handling: User-friendly messages with appropriate fallbacks
+- Authentication method: Standard session-based or OAuth2 for web apps
+- Integration patterns: RESTful APIs unless specified otherwise
+
+### Success Criteria Guidelines
+
+Success criteria must be:
+
+1. **Measurable**: Include specific metrics (time, percentage, count, rate)
+2. **Technology-agnostic**: No mention of frameworks, languages, databases, or tools
+3. **User-focused**: Describe outcomes from user/business perspective, not system internals
+4. **Verifiable**: Can be tested/validated without knowing implementation details
+
+**Good examples**:
+
+- "Users can complete checkout in under 3 minutes"
+- "System supports 10,000 concurrent users"
+- "95% of searches return results in under 1 second"
+- "Task completion rate improves by 40%"
+
+**Bad examples** (implementation-focused):
+
+- "API response time is under 200ms" (too technical, use "Users see results instantly")
+- "Database can handle 1000 TPS" (implementation detail, use user-facing metric)
+- "React components render efficiently" (framework-specific)
+- "Redis cache hit rate above 80%" (technology-specific)

+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+1. **Setup**: Run `.specify/scripts/bash/check-prerequisites.sh --json` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Load design documents**: Read from FEATURE_DIR:
+   - **Required**: plan.md (tech stack, libraries, structure), spec.md (user stories with priorities)
+   - **Optional**: data-model.md (entities), contracts/ (API endpoints), research.md (decisions), quickstart.md (test scenarios)
+   - Note: Not all projects have all documents. Generate tasks based on what's available.
+
+3. **Execute task generation workflow**:
+   - Load plan.md and extract tech stack, libraries, project structure
+   - Load spec.md and extract user stories with their priorities (P1, P2, P3, etc.)
+   - If data-model.md exists: Extract entities and map to user stories
+   - If contracts/ exists: Map endpoints to user stories
+   - If research.md exists: Extract decisions for setup tasks
+   - Generate tasks organized by user story (see Task Generation Rules below)
+   - Generate dependency graph showing user story completion order
+   - Create parallel execution examples per user story
+   - Validate task completeness (each user story has all needed tasks, independently testable)
+
+4. **Generate tasks.md**: Use `.specify/templates/tasks-template.md` as structure, fill with:
+   - Correct feature name from plan.md
+   - Phase 1: Setup tasks (project initialization)
+   - Phase 2: Foundational tasks (blocking prerequisites for all user stories)
+   - Phase 3+: One phase per user story (in priority order from spec.md)
+   - Each phase includes: story goal, independent test criteria, tests (if requested), implementation tasks
+   - Final Phase: Polish & cross-cutting concerns
+   - All tasks must follow the strict checklist format (see Task Generation Rules below)
+   - Clear file paths for each task
+   - Dependencies section showing story completion order
+   - Parallel execution examples per story
+   - Implementation strategy section (MVP first, incremental delivery)
+
+5. **Report**: Output path to generated tasks.md and summary:
+   - Total task count
+   - Task count per user story
+   - Parallel opportunities identified
+   - Independent test criteria for each story
+   - Suggested MVP scope (typically just User Story 1)
+   - Format validation: Confirm ALL tasks follow the checklist format (checkbox, ID, labels, file paths)
+
+Context for task generation: $ARGUMENTS
+
+The tasks.md should be immediately executable - each task must be specific enough that an LLM can complete it without additional context.
+
+## Task Generation Rules
+
+**CRITICAL**: Tasks MUST be organized by user story to enable independent implementation and testing.
+
+**Tests are OPTIONAL**: Only generate test tasks if explicitly requested in the feature specification or if user requests TDD approach.
+
+### Checklist Format (REQUIRED)
+
+Every task MUST strictly follow this format:
+
+```text
+- [ ] [TaskID] [P?] [Story?] Description with file path
+```
+
+**Format Components**:
+
+1. **Checkbox**: ALWAYS start with `- [ ]` (markdown checkbox)
+2. **Task ID**: Sequential number (T001, T002, T003...) in execution order
+3. **[P] marker**: Include ONLY if task is parallelizable (different files, no dependencies on incomplete tasks)
+4. **[Story] label**: REQUIRED for user story phase tasks only
+   - Format: [US1], [US2], [US3], etc. (maps to user stories from spec.md)
+   - Setup phase: NO story label
+   - Foundational phase: NO story label  
+   - User Story phases: MUST have story label
+   - Polish phase: NO story label
+5. **Description**: Clear action with exact file path
+
+**Examples**:
+
+- ✅ CORRECT: `- [ ] T001 Create project structure per implementation plan`
+- ✅ CORRECT: `- [ ] T005 [P] Implement authentication middleware in src/middleware/auth.py`
+- ✅ CORRECT: `- [ ] T012 [P] [US1] Create User model in src/models/user.py`
+- ✅ CORRECT: `- [ ] T014 [US1] Implement UserService in src/services/user_service.py`
+- ❌ WRONG: `- [ ] Create User model` (missing ID and Story label)
+- ❌ WRONG: `T001 [US1] Create model` (missing checkbox)
+- ❌ WRONG: `- [ ] [US1] Create User model` (missing Task ID)
+- ❌ WRONG: `- [ ] T001 [US1] Create model` (missing file path)
+
+### Task Organization
+
+1. **From User Stories (spec.md)** - PRIMARY ORGANIZATION:
+   - Each user story (P1, P2, P3...) gets its own phase
+   - Map all related components to their story:
+     - Models needed for that story
+     - Services needed for that story
+     - Endpoints/UI needed for that story
+     - If tests requested: Tests specific to that story
+   - Mark story dependencies (most stories should be independent)
+
+2. **From Contracts**:
+   - Map each contract/endpoint → to the user story it serves
+   - If tests requested: Each contract → contract test task [P] before implementation in that story's phase
+
+3. **From Data Model**:
+   - Map each entity to the user story(ies) that need it
+   - If entity serves multiple stories: Put in earliest story or Setup phase
+   - Relationships → service layer tasks in appropriate story phase
+
+4. **From Setup/Infrastructure**:
+   - Shared infrastructure → Setup phase (Phase 1)
+   - Foundational/blocking tasks → Foundational phase (Phase 2)
+   - Story-specific setup → within that story's phase
+
+### Phase Structure
+
+- **Phase 1**: Setup (project initialization)
+- **Phase 2**: Foundational (blocking prerequisites - MUST complete before user stories)
+- **Phase 3+**: User Stories in priority order (P1, P2, P3...)
+  - Within each story: Tests (if requested) → Models → Services → Endpoints → Integration
+  - Each phase should be a complete, independently testable increment
+- **Final Phase**: Polish & Cross-Cutting Concerns

+# Semantic Code Generation Constitution
+
+## Core Principles
+
+### I. Semantic Protocol Compliance
+The file `semantic_protocol.md` is the **authoritative technical standard** for this project. All code generation, refactoring, and architecture must strictly adhere to the standards, syntax, and workflows defined therein.
+- **Syntax**: `[DEF]` anchors, `@RELATION` tags, and metadata must match the Protocol specification.
+- **Structure**: File layouts and headers must follow the "File Structure Standard".
+- **Workflow**: The technical steps for generating code must align with the Protocol.
+
+### II. Causal Validity (Contracts First)
+As defined in the Protocol, Semantic definitions (Contracts) must ALWAYS precede implementation code. Logic is downstream of definition. We define the structure and constraints (`[DEF]`, `@PRE`, `@POST`) before writing the executable logic.
+
+### III. Immutability of Architecture
+Architectural decisions in the Module Header (`@LAYER`, `@INVARIANT`, `@CONSTRAINT`) are treated as immutable constraints. Changes to these require an explicit refactoring step, not ad-hoc modification during implementation.
+
+### IV. Design by Contract (DbC)
+Contracts are the Source of Truth. Functions and Classes must define their purpose, specifications, and constraints in the metadata block before implementation, strictly following the **Contracts (Section IV)** standard in `semantic_protocol.md`.
+
+### V. Belief State Logging
+Agents must maintain belief state logs for debugging and coherence checks, strictly following the **Logging Standard (Section V)** defined in `semantic_protocol.md`.
+
+### VI. Fractal Complexity Limit
+To maintain semantic coherence, code must adhere to the complexity limits (Module/Function size) defined in the **Fractal Complexity Limit (Section VI)** of `semantic_protocol.md`.
+
+### VII. Everything is a Plugin
+All functional extensions, tools, or major features must be implemented as modular Plugins inheriting from `PluginBase`. Logic should not reside in standalone services or scripts unless strictly necessary for core infrastructure. This ensures a unified execution model via the `TaskManager`, consistent logging, and modularity.
+
+## File Structure Standards
+Refer to **Section III (File Structure Standard)** in `semantic_protocol.md` for the authoritative definitions of:
+- Python Module Headers (`.py`)
+- Svelte Component Headers (`.svelte`)
+
+## Generation Workflow
+The development process follows a streamlined single-phase workflow:
+
+### 1. Code Generation Phase (Mode: `code`)
+**Input**: `tasks.md`
+**Responsibility**:
+- Select task from `tasks.md`.
+- Generate Scaffolding (`[DEF]` anchors, Headers, Contracts) AND Implementation in one pass.
+- Ensure strict adherence to Protocol Section IV (Contracts) and Section VII (Generation Workflow).
+- **Output**: Working code with passing tests.
+
+### 2. Validation
+If logic conflicts with Contract -> Stop -> Report Error.
+
+## Governance
+This Constitution establishes the "Semantic Code Generation Protocol" as the supreme law of this repository.
+
+- **Authoritative Source**: `semantic_protocol.md` defines the specific implementation rules for these Principles.
+- **Automated Enforcement**: Tools must validate adherence to the `semantic_protocol.md` syntax.
+- **Amendments**: Changes to core principles require a Constitution amendment. Changes to technical syntax require a Protocol update.
+- **Compliance**: Failure to adhere to the Protocol constitutes a build failure.

+
+# Update agent context files with information from plan.md
+#
+# This script maintains AI agent context files by parsing feature specifications 
+# and updating agent-specific configuration files with project information.
+#
+# MAIN FUNCTIONS:
+# 1. Environment Validation
+#    - Verifies git repository structure and branch information
+#    - Checks for required plan.md files and templates
+#    - Validates file permissions and accessibility
+#
+# 2. Plan Data Extraction
+#    - Parses plan.md files to extract project metadata
+#    - Identifies language/version, frameworks, databases, and project types
+#    - Handles missing or incomplete specification data gracefully
+#
+# 3. Agent File Management
+#    - Creates new agent context files from templates when needed
+#    - Updates existing agent files with new project information
+#    - Preserves manual additions and custom configurations
+#    - Supports multiple AI agent formats and directory structures
+#
+# 4. Content Generation
+#    - Generates language-specific build/test commands
+#    - Creates appropriate project directory structures
+#    - Updates technology stacks and recent changes sections
+#    - Maintains consistent formatting and timestamps
+#
+# 5. Multi-Agent Support
+#    - Handles agent-specific file paths and naming conventions
+#    - Supports: Claude, Gemini, Copilot, Cursor, Qwen, opencode, Codex, Windsurf, Kilo Code, Auggie CLI, Roo Code, CodeBuddy CLI, Qoder CLI, Amp, SHAI, or Amazon Q Developer CLI
+#    - Can update single agents or all existing agent files
+#    - Creates default Claude file if no agent files exist
+#
+# Usage: ./update-agent-context.sh [agent_type]
+# Agent types: claude|gemini|copilot|cursor-agent|qwen|opencode|codex|windsurf|kilocode|auggie|shai|q|bob|qoder
+# Leave empty to update all existing agent files

+**Feature Branch**: `[###-feature-name]`  
+**Created**: [DATE]  
+**Status**: Draft  
+**Input**: User description: "$ARGUMENTS"
+
+## User Scenarios & Testing *(mandatory)*
+
+<!--
+  IMPORTANT: User stories should be PRIORITIZED as user journeys ordered by importance.
+  Each user story/journey must be INDEPENDENTLY TESTABLE - meaning if you implement just ONE of them,
+  you should still have a viable MVP (Minimum Viable Product) that delivers value.
+  
+  Assign priorities (P1, P2, P3, etc.) to each story, where P1 is the most critical.
+  Think of each story as a standalone slice of functionality that can be:
+  - Developed independently
+  - Tested independently
+  - Deployed independently
+  - Demonstrated to users independently
+-->
+
+### User Story 1 - [Brief Title] (Priority: P1)
+
+[Describe this user journey in plain language]
+
+**Why this priority**: [Explain the value and why it has this priority level]
+
+**Independent Test**: [Describe how this can be tested independently - e.g., "Can be fully tested by [specific action] and delivers [specific value]"]
+
+**Acceptance Scenarios**:
+
+1. **Given** [initial state], **When** [action], **Then** [expected outcome]
+2. **Given** [initial state], **When** [action], **Then** [expected outcome]

+[Describe this user journey in plain language]
+
+**Why this priority**: [Explain the value and why it has this priority level]
+
+**Independent Test**: [Describe how this can be tested independently]
+
+**Acceptance Scenarios**:

+
+---
+
+[Add more user stories as needed, each with an assigned priority]
+
+### Edge Cases
+
+<!--
+  ACTION REQUIRED: The content in this section represents placeholders.
+  Fill them out with the right edge cases.
+-->
+
+- What happens when [boundary condition]?
+- How does system handle [error scenario]?
+
+## Requirements *(mandatory)*
+
+<!--
+  ACTION REQUIRED: The content in this section represents placeholders.
+  Fill them out with the right functional requirements.
+-->
+
+### Functional Requirements
+
+- **FR-001**: System MUST [specific capability, e.g., "allow users to create accounts"]
+- **FR-002**: System MUST [specific capability, e.g., "validate email addresses"]  
+- **FR-003**: Users MUST be able to [key interaction, e.g., "reset their password"]
+- **FR-004**: System MUST [data requirement, e.g., "persist user preferences"]
+- **FR-005**: System MUST [behavior, e.g., "log all security events"]
+
+*Example of marking unclear requirements:*
+
+- **FR-006**: System MUST authenticate users via [NEEDS CLARIFICATION: auth method not specified - email/password, SSO, OAuth?]
+- **FR-007**: System MUST retain user data for [NEEDS CLARIFICATION: retention period not specified]
+
+### Key Entities *(include if feature involves data)*
+
+- **[Entity 1]**: [What it represents, key attributes without implementation]
+- **[Entity 2]**: [What it represents, relationships to other entities]
+
+## Success Criteria *(mandatory)*
+
+<!--
+  ACTION REQUIRED: Define measurable success criteria.
+  These must be technology-agnostic and measurable.
+-->
+
+### Measurable Outcomes
+
+- **SC-001**: [Measurable metric, e.g., "Users can complete account creation in under 2 minutes"]
+- **SC-002**: [Measurable metric, e.g., "System handles 1000 concurrent users without degradation"]
+- **SC-003**: [User satisfaction metric, e.g., "90% of users successfully complete primary task on first attempt"]
+- **SC-004**: [Business metric, e.g., "Reduce support tickets related to [X] by 50%"]

+
+# Tasks: [FEATURE NAME]
+
+**Input**: Design documents from `/specs/[###-feature-name]/`
+**Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, contracts/
+
+**Tests**: The examples below include test tasks. Tests are OPTIONAL - only include them if explicitly requested in the feature specification.
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3)
+- Include exact file paths in descriptions
+
+## Path Conventions
+
+- **Single project**: `src/`, `tests/` at repository root
+- **Web app**: `backend/src/`, `frontend/src/`
+- **Mobile**: `api/src/`, `ios/src/` or `android/src/`
+- Paths shown below assume single project - adjust based on plan.md structure
+
+<!-- 
+  ============================================================================
+  IMPORTANT: The tasks below are SAMPLE TASKS for illustration purposes only.
+  
+  The /speckit.tasks command MUST replace these with actual tasks based on:
+  - User stories from spec.md (with their priorities P1, P2, P3...)
+  - Feature requirements from plan.md
+  - Entities from data-model.md
+  - Endpoints from contracts/
+  
+  Tasks MUST be organized by user story so each story can be:
+  - Implemented independently
+  - Tested independently
+  - Delivered as an MVP increment
+  
+  DO NOT keep these sample tasks in the generated tasks.md file.
+  ============================================================================
+-->
+
+## Phase 1: Setup (Shared Infrastructure)
+
+**Purpose**: Project initialization and basic structure
+
+- [ ] T001 Create project structure per implementation plan
+- [ ] T002 Initialize [language] project with [framework] dependencies
+- [ ] T003 [P] Configure linting and formatting tools
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Core infrastructure that MUST be complete before ANY user story can be implemented
+
+**⚠️ CRITICAL**: No user story work can begin until this phase is complete
+
+Examples of foundational tasks (adjust based on your project):
+
+- [ ] T004 Setup database schema and migrations framework
+- [ ] T005 [P] Implement authentication/authorization framework
+- [ ] T006 [P] Setup API routing and middleware structure
+- [ ] T007 Create base models/entities that all stories depend on
+- [ ] T008 Configure error handling and logging infrastructure
+- [ ] T009 Setup environment configuration management
+
+**Checkpoint**: Foundation ready - user story implementation can now begin in parallel
+
+---
+
+## Phase 3: User Story 1 - [Title] (Priority: P1) 🎯 MVP
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 1 (OPTIONAL - only if tests requested) ⚠️
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T010 [P] [US1] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T011 [P] [US1] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 1
+
+- [ ] T012 [P] [US1] Create [Entity1] model in src/models/[entity1].py
+- [ ] T013 [P] [US1] Create [Entity2] model in src/models/[entity2].py
+- [ ] T014 [US1] Implement [Service] in src/services/[service].py (depends on T012, T013)
+- [ ] T015 [US1] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T016 [US1] Add validation and error handling
+- [ ] T017 [US1] Add logging for user story 1 operations
+
+**Checkpoint**: At this point, User Story 1 should be fully functional and testable independently
+
+---
+
+## Phase 4: User Story 2 - [Title] (Priority: P2)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 2 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T018 [P] [US2] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T019 [P] [US2] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 2
+
+- [ ] T020 [P] [US2] Create [Entity] model in src/models/[entity].py
+- [ ] T021 [US2] Implement [Service] in src/services/[service].py
+- [ ] T022 [US2] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T023 [US2] Integrate with User Story 1 components (if needed)
+
+**Checkpoint**: At this point, User Stories 1 AND 2 should both work independently
+
+---
+
+## Phase 5: User Story 3 - [Title] (Priority: P3)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 3 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T024 [P] [US3] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T025 [P] [US3] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 3
+
+- [ ] T026 [P] [US3] Create [Entity] model in src/models/[entity].py
+- [ ] T027 [US3] Implement [Service] in src/services/[service].py
+- [ ] T028 [US3] Implement [endpoint/feature] in src/[location]/[file].py
+
+**Checkpoint**: All user stories should now be independently functional
+
+---
+
+[Add more user story phases as needed, following the same pattern]
+
+---
+
+## Phase N: Polish & Cross-Cutting Concerns
+
+**Purpose**: Improvements that affect multiple user stories
+
+- [ ] TXXX [P] Documentation updates in docs/
+- [ ] TXXX Code cleanup and refactoring
+- [ ] TXXX Performance optimization across all stories
+- [ ] TXXX [P] Additional unit tests (if requested) in tests/unit/
+- [ ] TXXX Security hardening
+- [ ] TXXX Run quickstart.md validation
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies - can start immediately
+- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
+- **User Stories (Phase 3+)**: All depend on Foundational phase completion
+  - User stories can then proceed in parallel (if staffed)
+  - Or sequentially in priority order (P1 → P2 → P3)
+- **Polish (Final Phase)**: Depends on all desired user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
+- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - May integrate with US1 but should be independently testable
+- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - May integrate with US1/US2 but should be independently testable
+
+### Within Each User Story
+
+- Tests (if included) MUST be written and FAIL before implementation
+- Models before services
+- Services before endpoints
+- Core implementation before integration
+- Story complete before moving to next priority
+
+### Parallel Opportunities
+
+- All Setup tasks marked [P] can run in parallel
+- All Foundational tasks marked [P] can run in parallel (within Phase 2)
+- Once Foundational phase completes, all user stories can start in parallel (if team capacity allows)
+- All tests for a user story marked [P] can run in parallel
+- Models within a story marked [P] can run in parallel
+- Different user stories can be worked on in parallel by different team members
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# Launch all tests for User Story 1 together (if tests requested):
+Task: "Contract test for [endpoint] in tests/contract/test_[name].py"
+Task: "Integration test for [user journey] in tests/integration/test_[name].py"
+
+# Launch all models for User Story 1 together:
+Task: "Create [Entity1] model in src/models/[entity1].py"
+Task: "Create [Entity2] model in src/models/[entity2].py"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup
+2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
+3. Complete Phase 3: User Story 1
+4. **STOP and VALIDATE**: Test User Story 1 independently
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Complete Setup + Foundational → Foundation ready
+2. Add User Story 1 → Test independently → Deploy/Demo (MVP!)
+3. Add User Story 2 → Test independently → Deploy/Demo
+4. Add User Story 3 → Test independently → Deploy/Demo
+5. Each story adds value without breaking previous stories
+
+### Parallel Team Strategy
+
+With multiple developers:
+
+1. Team completes Setup + Foundational together
+2. Once Foundational is done:
+   - Developer A: User Story 1
+   - Developer B: User Story 2
+   - Developer C: User Story 3
+3. Stories complete and integrate independently
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story should be independently completable and testable
+- Verify tests fail before implementing
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently
+- Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence

-                **Фаза 0: Синхронизация с Контекстом Проекта**
-                Обнаружен и загружен `PROJECT_SEMANTICS.xml`. Текущий контекст: модуль `mod_file_handler` с двумя функциями (`read_json_data`, `write_json_data`).
-
-                **Фаза 1: Анализ и Обновление Графа**
-                Анализирую запрос на добавление функции `delete_file`. Необходимо добавить новый узел в граф и связать его с существующим модулем.
-                
-                **Обновленный Семантический Граф:**

-                **Фаза 2: Контрактно-Ориентированное Проектирование**
-                Граф обновлен. Проектирую контракт для новой функции `delete_file`.

 3. **Настройте пароли:**
     Используйте `keyring` для хранения паролей API-пользователей Superset.
-    Пример для `backup_script.py`:
     ```python
     import keyring
     keyring.set_password("system", "dev migrate", "пароль пользователя migrate_user")
     keyring.set_password("system", "prod migrate", "пароль пользователя migrate_user")
     keyring.set_password("system", "sandbox migrate", "пароль пользователя migrate_user")
     ```
-    При необходимости замените `"system"` на подходящее имя сервиса.
 
 ## Использование
 
+### Запуск проекта (Web UI)
+Для запуска backend и frontend серверов одной командой:
+```bash
+./run.sh
+```
+Опции:
+- `--skip-install`: Пропустить проверку и установку зависимостей.
+- `--help`: Показать справку.
+
+Переменные окружения:
+- `BACKEND_PORT`: Порт для backend (по умолчанию 8000).
+- `FRONTEND_PORT`: Порт для frontend (по умолчанию 5173).
+
 ### Скрипт резервного копирования (`backup_script.py`)

 ```bash
 python migration_script.py
 ```
-**Примечание:** В текущей версии скрипт переносит жестко заданный дашборд (`FI0070`) и использует локальный `.zip` файл в качестве источника. **Для использования в Production необходимо:**
-- В текущей версии управление откуда и куда выполняется параметрами
-`from_c` и `to_c`.
 
 ### Скрипт поиска (`search_script.py`)
-Строка для поиска и клиенты для поиска задаются здесь
+Для поиска по текстовым паттернам в метаданных датасетов Superset:
-# Поиск всех таблиц в датасете
+```bash
-```python
+python search_script.py
-results = search_datasets(
-    client=clients['dev'],
-    search_pattern=r'dm_view\.account_debt',
-    search_fields=["sql"],
-    logger=logger
-)
 ```
+Скрипт использует регулярные выражения для поиска в полях датасетов, таких как SQL-запросы. Результаты поиска выводятся в лог и в консоль.
 
+### Скрипт маппинга метаданных (`run_mapper.py`)
+Для обновления метаданных датасета (например, verbose names) в Superset:
+```bash
+python run_mapper.py --source <source_type> --dataset-id <dataset_id> [--table-name <table_name>] [--table-schema <table_schema>] [--excel-path <path_to_excel>] [--env <environment>]
+```
+Если вы используете XLSX - файл должен содержать два столбца - column_name | verbose_name
+
+
+Параметры:
+- `--source`: Источник данных ('postgres', 'excel' или 'both').
+- `--dataset-id`: ID датасета для обновления.
+- `--table-name`: Имя таблицы для PostgreSQL.
+- `--table-schema`: Схема таблицы для PostgreSQL.
+- `--excel-path`: Путь к Excel-файлу.
+- `--env`: Окружение Superset ('dev', 'prod' и т.д.).
+
+Пример использования:
+```bash
+python run_mapper.py --source postgres --dataset-id 123 --table-name account_debt --table-schema dm_view --env dev
+
+python run_mapper.py --source=excel --dataset-id=286 --excel-path=H:\dev\ss-tools\286_map.xlsx --env=dev
+```
 
 ## Логирование
 Логи пишутся в файл в директории `Logs` (например, `P:\Superset\010 Бекапы\Logs` для резервных копий) и выводятся в консоль. Уровень логирования по умолчанию — `INFO`.
 
 ## Разработка и вклад
-- Следуйте архитектурным паттернам (`[MODULE]`, `[CONTRACT]`, `[SECTION]`, `[ANCHOR]`) и правилам логирования.
+- Следуйте **Semantic Code Generation Protocol** (см. `semantic_protocol.md`):
-- Весь новый код должен соответствовать принципам "LLM-friendly" генерации.
+    - Все определения обернуты в `[DEF]...[/DEF]`.
+    - Контракты (`@PRE`, `@POST`) определяются ДО реализации.
+    - Строгая типизация и иммутабельность архитектурных решений.
+- Соблюдайте Конституцию проекта (`.specify/memory/constitution.md`).
 - Используйте `Pydantic`-модели для валидации данных.
 - Реализуйте всестороннюю обработку ошибок с помощью пользовательских исключений.

+# Database Mapping in Migration
+
+This document describes how to use the database mapping feature during Superset dashboard migrations.
+
+## Overview
+
+When migrating dashboards between different Superset environments (e.g., from Dev to Prod), the underlying databases often have different UUIDs even if they represent the same data source. The Database Mapping feature allows you to define these relationships so that migrated assets automatically point to the correct database in the target environment.
+
+## How it Works
+
+1.  **Fuzzy Matching**: The system automatically suggests mappings by comparing database names between environments using the RapidFuzz library.
+2.  **Persistence**: Mappings are stored in a local SQLite database (`mappings.db`) and are reused for future migrations between the same environment pair.
+3.  **Asset Interception**: During migration, the system intercepts the Superset export ZIP archive, modifies the `database_uuid` in the dataset YAML files, and re-packages the archive before importing it to the target.
+
+## Usage Instructions
+
+### 1. Define Mappings
+
+1.  Navigate to the **Database Mapping** tab in the application.
+2.  Select your **Source** and **Target** environments.
+3.  Click **Fetch Databases & Suggestions**.
+4.  Review the suggested mappings (highlighted in green).
+5.  If a suggestion is incorrect or missing, use the dropdown in the "Target Database" column to select the correct one.
+6.  Mappings are saved automatically when you select a target database.
+
+### 2. Run Migration with Database Replacement
+
+1.  Go to the **Migration** dashboard.
+2.  Select the **Source** and **Target** environments.
+3.  Select the dashboards or datasets you want to migrate.
+4.  Enable the **Replace Database (Apply Mappings)** toggle.
+5.  Click **Start Migration**.
+
+### 3. Handling Missing Mappings
+
+If the migration engine encounters a database that has no defined mapping, the process will pause, and a modal will appear prompting you to select a target database on-the-fly. Once selected, the mapping is saved, and the migration continues.
+
+## Troubleshooting
+
+-   **Mapping not applied**: Ensure the "Replace Database" toggle is enabled.
+-   **Wrong database in target**: Check the mapping table for the specific environment pair and correct any errors.
+-   **Connection errors**: Ensure both Superset environments are reachable and credentials are correct in Settings.

+# Plugin Development Guide
+
+This guide explains how to create new plugins for the Superset Tools application.
+
+## 1. Plugin Structure
+
+A plugin is a single Python file located in the `backend/src/plugins/` directory. Each plugin file must contain a class that inherits from `PluginBase`.
+
+## 2. Implementing `PluginBase`
+
+The `PluginBase` class is an abstract base class that defines the interface for all plugins. You must implement the following properties and methods:
+
+- **`id`**: A unique string identifier for your plugin (e.g., `"my-cool-plugin"`).
+- **`name`**: A human-readable name for your plugin (e.g., `"My Cool Plugin"`).
+- **`description`**: A brief description of what your plugin does.
+- **`version`**: The version of your plugin (e.g., `"1.0.0"`).
+- **`get_schema()`**: A method that returns a JSON schema dictionary defining the input parameters for your plugin. This schema is used to automatically generate a form in the frontend.
+- **`execute(params: Dict[str, Any])`**: An `async` method that contains the main logic of your plugin. The `params` argument is a dictionary containing the input data from the user, validated against the schema you defined.
+
+## 3. Example Plugin
+
+Here is an example of a simple "Hello World" plugin:
+
+```python
+# backend/src/plugins/hello.py
+# [DEF:HelloWorldPlugin:Plugin]
+# @SEMANTICS: hello, world, example, plugin
+# @PURPOSE: A simple "Hello World" plugin example.
+# @LAYER: Domain (Plugin)
+# @RELATION: Inherits from PluginBase
+# @PUBLIC_API: execute
+
+from typing import Dict, Any
+from ..core.plugin_base import PluginBase
+
+class HelloWorldPlugin(PluginBase):
+    @property
+    def id(self) -> str:
+        return "hello-world"
+
+    @property
+    def name(self) -> str:
+        return "Hello World"
+
+    @property
+    def description(self) -> str:
+        return "A simple plugin that prints a greeting."
+
+    @property
+    def version(self) -> str:
+        return "1.0.0"
+
+    def get_schema(self) -> Dict[str, Any]:
+        return {
+            "type": "object",
+            "properties": {
+                "name": {
+                    "type": "string",
+                    "title": "Name",
+                    "description": "The name to greet.",
+                    "default": "World",
+                }
+            },
+            "required": ["name"],
+        }
+
+    async def execute(self, params: Dict[str, Any]):
+        name = params["name"]
+        print(f"Hello, {name}!")
+```
+
+## 4. Logging
+
+You can use the global logger instance to log messages from your plugin. The logger is available in the `superset_tool.utils.logger` module.
+
+```python
+from superset_tool.utils.logger import SupersetLogger
+
+logger = SupersetLogger()
+
+async def execute(self, params: Dict[str, Any]):
+    logger.info("My plugin is running!")
+```
+
+## 5. Testing
+
+To test your plugin, simply run the application and navigate to the web UI. Your plugin should appear in the list of available tools.

+# Web Application Settings Mechanism
+
+This document describes the settings management system for the Superset Tools application.
+
+## Overview
+
+The settings mechanism allows users to configure multiple Superset environments and global application settings (like backup storage) via the web UI.
+
+## Backend Architecture
+
+### Data Models
+
+Configuration is structured using Pydantic models in `backend/src/core/config_models.py`:
+
+- `Environment`: Represents a Superset instance (URL, credentials). The `base_url` is automatically normalized to include the `/api/v1` suffix if missing.
+- `GlobalSettings`: Global application parameters (e.g., `backup_path`).
+- `AppConfig`: The root configuration object.
+
+### Configuration Manager
+
+The `ConfigManager` (`backend/src/core/config_manager.py`) handles:
+- Persistence to `config.json`.
+- CRUD operations for environments.
+- Validation and logging.
+
+### API Endpoints
+
+The settings API is available at `/settings`:
+
+- `GET /settings`: Retrieve all settings (passwords are masked).
+- `PATCH /settings/global`: Update global settings.
+- `GET /settings/environments`: List environments.
+- `POST /settings/environments`: Add environment.
+- `PUT /settings/environments/{id}`: Update environment.
+- `DELETE /settings/environments/{id}`: Remove environment.
+- `POST /settings/environments/{id}/test`: Test connection.
+
+## Frontend Implementation
+
+The settings page is located at `frontend/src/pages/Settings.svelte`. It provides forms for managing global settings and Superset environments.
+
+## Integration
+
+Existing plugins and utilities use the `ConfigManager` to fetch configuration:
+- `superset_tool/utils/init_clients.py`: Dynamically initializes Superset clients from the configured environments.
+- `BackupPlugin`: Uses the configured `backup_path` as the default storage location.
