"Any page" language removed. | +| B2 (Gradio payload breakage) | uicontext appended at position END (6), not middle. Default None ensures backward-compat. | +| B3 (route field) | Spec clarifies route is passed via URL param `route=/dashboards/42`. | +| B4 (envId duality) | Env resolution canonical rule defined. `updateActiveEnv()` syncs both `_activeEnvId` AND `uiContext.envId`. | +| B5 (tool filtering inconsistency) | `build_tool_pipeline()` defines ordered pipeline: RBAC→context. "Prioritise" → "hard filter". Embedding router deferred to AGTL-FR-006 (SHOULD). | +| B6 (permission denied UX) | Permission denied flows to separate SSE event `permission_denied` — bypasses HITL checkpoint. Two-layer enforcement added. | +| B7 (impact estimate) | Removed from acceptance criteria — not implemented in this feature scope. | +| B8 (toolAffinity debug data) | Removed frontend-only `toolAffinity` atom. Debug tool list comes from backend SSE pipeline_result event. | +| B9 (UIContext trust model) | `validate_uicontext()` with enum checks, size limits, field lengths. Prompt block marked "not instructions". | +| B10 (traceability out of sync) | Traceability rebuilt from updated tasks and contract IDs. | +| M3 (contextVersion) | All examples include `contextVersion: 1`. | +| M4 (risk remains heuristic) | Documented as known limitation. Tool metadata (operation_type, idempotency, required_roles) deferred to tool registry ADR-0008 extension. | +| M5 (permission source) | User role extracted from JWT. `_TOOL_PERMISSIONS` dict defines tool→role mapping. | +| M6 (manual retry unsafe) | Write tool timeout: no retry button ("check operation status"). Read tool timeout: retry button. | +| M7 (timeout semantics) | Write tool timeout: `is_write_tool=true, retryable=false`. Frontend shows "operation status unknown" — no retry. | +| M8 (structured truncation naming) | Renamed from "semantic summarisation".

Stack Compatibility + +- [x] Backend context: Python 3.9+ / FastAPI / SQLAlchemy — feature is compatible (context enrichment is HTTP payload, not a new protocol) +- [x] Frontend context: SvelteKit 5 / Svelte 5 runes / Tailwind — feature uses existing patterns (Model atoms, $derived, component props) +- [x] No conflict with ADR-0003 (orchestrator pattern) — agent remains external orchestrator over Superset +- [x] No conflict with ADR-0006 (frontend architecture) — uses existing Model pattern, no legacy Svelte 4 stores +- [x] No conflict with ADR-0008 (tool registry) — RBAC tool filtering aligns with decorator registry design +- [x] No conflict with ADR-0005 (RBAC) — permission checks extend existing role model + +## 4.

Spec is ready for `/speckit.clarify` or `/speckit.plan`. + +**No blocking issues found.** The feature is well-scoped across three independent stories (context, guardrails, tools) that can be implemented and verified independently. The context enrichment is additive (doesn't break existing flows). Guardrails refinement extends existing HITL patterns.

enrichment** (P1): Frontend captures structured `UIContext` JSON from page state and passes it to the Gradio agent on each `sendMessage`. Agent uses context for (a) contextual responses without explicit object naming, (b) tool filtering by `objectType`. Context is route-level — transferred once when navigating to `/agent` page. +2. **Guardrails refinement** (P2): Risk classification extended from tool-name prefixes to include environment context and tool danger level. ConfirmationCard gains environment badges, destructive-operation countdown (10s), permission-denied state with alternatives, and visual risk toning. +3. **Tool optimisation** (P3): Backend: RBAC tool filtering, auto-retry on transient HTTP errors, semantic response summarisation, configurable tool timeout, context-aware tool affinity. Frontend: ToolCallCard extended with retry/timeout/cancelled states. + +## Technical Context + +**Language/Version**: Python 3.9+ (backend), TypeScript (frontend Svelte 5 runes-only) +**Primary Dependencies**: FastAPI, Gradio, LangChain (`create_react_agent`), LangGraph, LangChain-OpenAI (backend); SvelteKit 5, Svelte 5, Tailwind CSS 3, @gradio/client (frontend) +**Storage**: PostgreSQL 16 (checkpoints via PostgresSaver, conversations via SQLAlchemy) +**Testing**: pytest (backend), vitest (frontend — L1 model invariants without render + L2 UX with @testing-library/svelte) +**Target Platform**: Linux server (Docker), modern browsers +**Project Type**: web application (FastAPI REST + Gradio SSE backend, SvelteKit SPA frontend) +**Frontend Architecture**: TypeScript-first, model-first (Screen Models via `.svelte.ts`), runes-only (`$state`, `$derived`, `$effect`), typed callback props +**Performance Goals**: Context pill update <50ms, confirmation card render <200ms, tool retry <5s added latency +**Constraints**: RBAC enforcement (analyst cannot invoke write tools), backward-compat with existing Gradio submit API, no new database tables +**Scale/Scope**: ~10 concurrent agent chats, ~20 tools, 3 context types (dashboard/dataset/migration) + +## Constitution Check + +*GATE: Must pass before Phase 0 research.

Context Model — `/agent` Page (Path B) + +- **Decision**: Dedicated `/agent` page. User navigates from any page via «Спросить агента» button → `/agent?objectType=...&objectId=...&objectName=...&envId=...&route=...`. Context is static for visit duration, envId updatable via EnvSelector. +- **Rationale**: Simpler state management vs drawer overlay. No z-index conflicts, no $page.url reactivity tracking, no stale-context edge cases during navigation. Aligns with existing UX decisions. +- **Alternatives considered**: Drawer panel on any page (Path A) — rejected. Requires $page.url $effect tracking, cross-component context sync, fragile during page navigation mid-stream. +- **Impact**: `+page.svelte` reads URL params in `onMount`. `updateActiveEnv()` syncs `_activeEnvId` AND `uiContext.envId`. No `initialContext` in store. Context captured once, not per-message. + +## 2. Gradio Payload — uicontext at END + +- **Decision**: `uicontext_str` appended as position 6 in Gradio submit args: `[message, null, convId, userId, userJwt, envId, uicontext]`. +- **Rationale**: Middle-position insertion would shift existing arguments for clients built against the current 6-arg signature. Appending is truly backward-compatible — missing arg defaults to `None`. +- **Alternatives considered**: Position 3 insertion — rejected as BREAKING. +- **Impact**: `agent_handler()` signature: `uicontext_str=None` as last param. All existing callers pass 6 args → uicontext defaults to None. + +## 5. Tool Retry — Fixed 1s Delay + +- **Decision**: Single retry with fixed 1s `asyncio.sleep`. Read-only tools only. +- **Rationale**: "Exponential backoff" terminology was incorrect — single retry cannot be exponential. Fixed 1s is simple and catches transient failures without latency explosion. +- **Alternatives considered**: True exponential backoff (1s, 2s, 4s) — rejected (3 retries = 7s+ latency). Auto-retry write tools — rejected (idempotency risk). +- **Impact**: `_retry_read_tool()` in `tools.py`. `tool_retry` SSE event with attempt counter. + +## 6. Response Summarisation — Structured Truncation + +- **Decision**: "Semantic summarisation" renamed to "structured truncation". Top-5 items + total count for JSON arrays. Sentence-boundary truncation for text. Object keys + sample for JSON objects. +- **Rationale**: More accurate description — not true semantic summarisation, just preserving structure during truncation. +- **Impact**: `_summarise_response()` in `tools.py`. AGTL-FR-003 updated. + +## 7. Write Tool Timeout Safety + +- **Decision**: Write/mutating tool timeout produces `tool_timeout` with `is_write_tool=true, retryable=false`. Frontend shows "Operation status unknown — check Superset" — no retry button. +- **Rationale**: Timeout ≠ mutation didn't happen. Server may continue processing. Auto-retry or user retry could duplicate mutations. +- **Impact**: `_execute_with_timeout()` accepts `is_write` param. `tool_timeout` SSE extended with `is_write_tool` field. + +## 2. Tool Affinity Mapping (ContextToolAffinity) + +- **Decision**: Static server-side mapping `objectType → set[operation_name]`. Three groups: `dashboard` (9 tools), `dataset` (8 tools), `migration` (5 tools). `show_capabilities` always included. When `objectType=null`, all 22 tools returned (current behavior). +- **Rationale**: Static mapping is predictable, zero latency, auditable. The embedding router (`_embedding_router.py`) already exists but is unused — static mapping is more deterministic for context filtering. Embedding router can be added later as semantic fallback for `objectType=null`. +- **Alternatives considered**: LLM-based dynamic filtering — rejected (adds latency, non-deterministic). Embedding-only — rejected (model loading overhead, 200MB RAM). Client-side filtering — rejected (security — must be server-enforced). +- **Impact**: New file `backend/src/agent/_tool_filter.py`. `get_all_tools()` call site in `app.py` extended to accept `objectType` param. + +## 3. Tool Selection Pipeline + +- **Decision**: Ordered pipeline: (1) RBAC role-based exclusion, (2) context-type hard filter. `show_capabilities` always included. Embedding router deferred to post-MVP (AGTL-FR-006). +- **Rationale**: RBAC MUST run first (security). Context filtering is UX enhancement. Two-layer enforcement: prompt filtering + invocation guard catches hallucinated/direct calls. +- **Alternatives considered**: Embedding-first routing — rejected for initial release (200MB model, 50ms latency). Prioritisation (ranking) — rejected in favor of hard exclusion for predictability. +- **Impact**: `build_tool_pipeline()` in `_tool_filter.py`. `enforce_tool_permission()` invocation guard. AGTL-FR-005 rewritten as two-layer enforcement. + +## 4. Guardrails Risk Classification v2 + +- **Decision**: Three-axis risk: `tool_risk` (read/write/dangerous), `env_risk` (prod/staging/dev → normalised from env_id), `permission_risk` (RBAC check). Permission-denied flows to `permission_denied` SSE (NOT `confirm_required`). Env resolution: `tool_args.env_id > submit envId > UIContext.envId > null`. +- **Rationale**: Permission-denied MUST bypass HITL checkpoint — entering checkpoint for a known-forbidden call is a security anti-pattern. Separate event type lets frontend render without confirm button. +- **Alternatives considered**: `confirm_required` with `permission_granted=false` — rejected as security anti-pattern. +- **Impact**: `build_confirmation_contract_v2()`. `yield_permission_denied()`. New SSE event type. + +## 4. Dangerous Tool Countdown (10s) + +- **Decision**: Frontend-only countdown. When `dangerous=true` in confirmation metadata, confirm button disabled for 10 seconds with visual countdown. Backend does NOT enforce the delay — it's a UX guard, not a security control. Backend HITL interrupt already prevents automatic execution. +- **Rationale**: UX guard against impulse clicks on irreversible operations. Frontend-only because: (a) backend already has HITL checkpoint, (b) server-side delay would tie up Gradio worker for 10s, (c) user can still deny during countdown. +- **Alternatives considered**: Server-side delay — rejected (blocks worker). Two-step confirmation — rejected (user fatigue). Undo toast — rejected (many ops are irreversible at DB level). +- **Impact**: `ConfirmationCard.svelte` gains `$state(dangerousTimer)` + `setInterval`. `AgentChatModel` gains `dangerousCountdown`/`dangerousCountdownActive` atoms. + +## 5. Tool Retry Strategy + +- **Decision**: Hybrid. Backend auto-retries ONCE with 1s exponential backoff for read-only tools on transient HTTP errors (502/503/504, connection errors). Both attempts fail → `tool_error` event with `retry_exhausted:true`. Frontend ToolCallCard shows `retrying` state during auto-retry, then ❌ + manual «Повторить» button on exhaustion. +- **Rationale**: One auto-retry catches 80% of transient failures without user intervention. Manual retry gives user control when auto-retry fails. Read-only only because mutating operations must not auto-retry (idempotency not guaranteed). +- **Alternatives considered**: Auto-retry all tools — rejected (write idempotency risk). No auto-retry — rejected (transient 502s frustrate users). Exponential backoff with 3+ retries — rejected (adds 7s+ latency). +- **Impact**: Tool wrapper in `tools.py` gains `_retry_wrapper()`. New SSE event types: `tool_retry`, extended `tool_error`. + +## 6. Response Summarisation + +- **Decision**: Server-side. When tool response >4000 chars, extract top-N items (N=5) + total count header. Format: `"Found X items:\n - item1\n - item2\n ...\n and (X-5) more items."` Applied BEFORE response enters LLM context window. +- **Rationale**: Hard truncation at 4000 loses structure (mid-JSON). Semantic summarisation preserves: (a) result count, (b) representative samples, (c) ability to query further if needed. +- **Alternatives considered**: Client-side summarisation — rejected (LLM already consumed full response). LLM summarisation — rejected (extra LLM call, token cost). Pagination in tools — rejected (requires tool rework for all 22 tools). +- **Impact**: New helper `_summarise_response()` in `tools.py`. Called inside `_trim_response()` replacement. No API shape change. + +## 7. Context Passing on /agent Page + +- **Decision**: Route-level context. When user navigates from `/dashboards/42?env_id=ss-dev` to `/agent?objectType=dashboard&objectId=42&envId=ss-dev`, the `/agent` page reads URL params in `onMount` and calls `model.setUIContextFromParams()`. Context pill in process steps shows «📋 Дашборд #42 · ss-dev». Env can be changed via EnvSelector on the agent page — `model.updateActiveEnv()` updates `isProdContext` reactively. +- **Rationale**: Agent page is a dedicated route — no further navigation happens during chat. Context is static per-visit, reducing complexity. URL params survive page refresh. +- **Alternatives considered**: Live page tracking via `$effect` — rejected (no navigation on `/agent`). Lazy on send — rejected (user wants to see context before sending). +- **Impact**: `+page.svelte` `onMount` reads URL params. `assistantChatStore` extended with `initialContext`. No routing changes needed — params are additive. + +## 8.

Контекст страницы-источника передаётся через query-параметры URL при навигации: `objectType`, `objectId`, `objectName`, `envId`, `route`. Фронтенд на странице `/agent` читает эти параметры в `onMount` и формирует `UIContext` JSON. Контекст статичен в рамках визита на `/agent` — повторные сообщения используют тот же контекст. Смена окружения через EnvSelector возможна и обновляет `envId` для последующих сообщений. Пример: со страницы `http://localhost:5173/dashboards/10?env_id=ss-dev` кнопка «Спросить агента» ведёт на `/agent?objectType=dashboard&objectId=10&objectName=Отчёт%20по%20энергопотреблению&envId=ss-dev&route=/dashboards/10`. +- **Инструменты, релевантные контексту**: Список инструментов, доступных LLM, **фильтруется** (жёсткое исключение, не приоритизация) по `objectType`. `dashboard` → только дашборд-ориентированные инструменты; `dataset` → датасет-ориентированные; `null`/отсутствует → полный набор разрешённых инструментов. `show_capabilities` всегда включён. + +## User Scenarios + +Each story is an independently testable unit. Prioritized P1 (MVP) → P2 → P3. +All stories share `@SEMANTICS` domain keywords from the feature header. + +### Story 1 — Context-Aware Agent on `/agent` Page (P1) + +**Why P1**: Пользователь переходит на выделенную страницу агента (`/agent`) с любой страницы сервиса по кнопке «Спросить агента». Контекст страницы-источника передаётся через query-параметры URL: `objectType`, `objectId`, `objectName`, `envId`, `route`. Агент, получив этот контекст, должен: (а) понимать, на каком объекте находился пользователь — отвечать контекстно без явного называния объекта; (б) фильтровать доступные инструменты по типу объекта — дашборд-ориентированные для дашборда, датасет-ориентированные для датасета. Контекст статичен в рамках визита на `/agent`; смена окружения через EnvSelector обновляет `envId`. + +**Independent Test**: Со страницы дашборда (`/dashboards/10?env_id=ss-dev`) нажать «Спросить агента» → переход на `/agent?objectType=dashboard&objectId=10&envId=ss-dev...`. Спросить «расскажи про этот дашборд» — агент: (1) отвечает с информацией о дашборде id=10 не требуя названия; (2) использует только дашборд-ориентированные инструменты, а не общий список из 22 тулов. + +**Acceptance**: +1. **Given** пользователь на странице дашборда нажимает «Спросить агента» и переходит на `/agent?objectType=dashboard&objectId=10&envId=ss-dev` **When** спрашивает «какой статус у этого дашборда?» **Then** агент понимает, что речь о дашборде id=10 в окружении `ss-dev`, и отвечает с git-статусом, датой изменения, результатами валидации — без явного указания названия или ID. +2. **Given** переход на `/agent?objectType=dataset&objectId=15&envId=staging` **When** агент вызван и спрашивают «есть ли проблемы с этим датасетом?» **Then** агент использует dataset id=15, staging и отвечает про маппинги, зависимости, статус ревью. +3. **Given** `objectType: "dashboard"` в контексте **When** агент формирует набор инструментов для LLM **Then** только дашборд-ориентированные инструменты (`search_dashboards`, `get_health_summary`, `deploy_dashboard`, `run_llm_validation`, `run_llm_documentation`, `execute_migration`, `create_branch`, `commit_changes`, `show_capabilities`) доступны; нерелевантные (`superset_explore_database`, `run_backup` и др.) — исключены. +4. **Given** `objectType: "dataset"` **When** агент формирует набор инструментов **Then** только датасет-ориентированные (`superset_explore_database`, `superset_format_sql`, `superset_audit_permissions`, `superset_execute_sql`, `superset_create_dataset`, `search_dashboards`, `get_task_status`, `list_environments`, `show_capabilities`) доступны. +5. **Given** пользователь переходит с дашборда A на страницу агента, затем возвращается и переходит с дашборда B **When** агент вызывается снова со страницы B **Then** новый `objectId` в URL — никакого залипания старого контекста. +6. **Given** пользователь на странице без контекстного объекта (переход с `/settings`) **When** агент вызывается (URL без `objectType`) **Then** агент работает в общем режиме с полным набором доступных инструментов. + +--- + +### Story 2 — Guardrails Card Refinement (P2) + +**Why P2**: The current confirmation card shows tool name and arguments with a simple confirm/deny. Risk classification is a heuristic based on tool name prefixes only — it does not consider the environment (production vs staging), the scope of data affected, or the user's role. Users need richer context to make informed confirmation decisions, and guardrails should adapt to actual risk, not just tool category. + +**Independent Test**: Trigger a guarded tool (e.g., `deploy_dashboard` to production) — the confirmation card shows environment badge («⚠️ PRODUCTION»), estimated impact scope («3 дашборда будут изменены»), and a contextualised warning. Trigger the same tool to staging — the card shows a lower-severity styling. + +**Acceptance**: +1. **Given** the agent calls `deploy_dashboard` targeting the `prod` environment **When** a confirmation is triggered **Then** the card displays a «production» risk badge with destructive-tone styling, warns about the target environment, and requires explicit confirmation. +2. **Given** the same tool targets a `dev` or `staging` environment **When** a confirmation is triggered **Then** the card displays a lower-risk badge (info-tone), and the prompt is less alarming («Изменения в dev-окружении»). +3. **Given** the agent calls a read-only tool (e.g., `search_dashboards`) with HITL enabled **When** a confirmation is required **Then** the card clearly labels the action as «чтение данных» with distinct visual treatment (success-tone, no warning icon) — the user immediately distinguishes read from write confirmations. +4. **Given** the user's role lacks permission for a requested tool **When** the agent attempts the tool call **Then** the confirmation is pre-rejected server-side — the card displays «Недостаточно прав» with the required role shown and no confirm button (only a dismiss). +5. **Given** the user dismisses or denies a confirmation **When** the action is cancelled **Then** the agent does NOT proceed silently — it returns a clear cancellation message in the chat stream. + +--- + +### Story 3 — Tool Execution Optimisation (P3) + +**Why P3**: The agent currently invokes tools via HTTP to FastAPI with no retry logic, no response-size awareness beyond a hard truncation limit, and no tool-level access control based on user role. Large responses waste LLM context window; network flakes cause avoidable failures; role-inappropriate tools unnecessarily confuse the LLM. + +**Independent Test**: Trigger `run_backup` as an analyst user — the tool is not offered to the LLM. Trigger `search_dashboards` with a large result set — the response is intelligently summarised. Simulate a transient FastAPI error — the tool retries once and succeeds. + +**Acceptance**: +1. **Given** the user has role `analyst` (no write permissions for git/deploy) **When** the agent's tool set is assembled **Then** write tools (`deploy_dashboard`, `commit_changes`, `create_branch`) are excluded from the LLM's available tools — the agent cannot even propose them. +2. **Given** a tool call to FastAPI returns a transient 502/503 error **When** the tool is a read-only query **Then** the agent retries once (with exponential backoff) before reporting failure to the user. +3. **Given** a tool returns >4000 characters of raw JSON **When** the response is prepared for the LLM **Then** structured data is summarised (top-N items + count) rather than hard-truncated mid-structure, preserving semantic value. +4. **Given** a tool invocation hangs (no response for 30 seconds) **When** the timeout elapses **Then** the agent receives a clear timeout error and can attempt an alternative approach or report the issue — the chat does not hang indefinitely. +5. **Given** the embedding router is available **When** the LLM selects tools **Then** the tool set passed to the LLM is restricted to the top-K semantically relevant tools (plus the mandatory capabilities tool), reducing prompt size and improving LLM tool-selection accuracy. + +--- + +### Edge Cases +- User navigates from dashboard page to `/agent` with context, closes tab, reopens from another dashboard → fresh context from new URL parameters. +- No environment is selected in the UI → переход на `/agent` без `envId`; agent operates in environment-agnostic mode (cannot use env-specific tools). +- The user's JWT expires mid-conversation → the next tool call fails with 401; agent reports «сессия истекла, обновите страницу» without retrying. +- Conversation is restored from history that was created before context enrichment → old messages lack `uicontext` JSON; agent gracefully degrades to «контекст недоступен». +- HITL confirmation is pending when the Gradio connection drops → state is preserved in the LangGraph checkpoint; on reconnect, the backend re-emits `confirm_required` for the pending checkpoint. +- Multiple browser tabs have the agent chat open → each tab derives independent context from its own URL parameters; no cross-tab interference. +- Malformed `objectType` in URL (e.g. `?objectType=invalid`) → frontend treats as `null`; backend validation rejects unknown enum values with 422. + +## Requirements + +### Functional (IDs survive HCA 128× via hierarchical naming) + +- **AGCTX-FR-001**: При переходе на `/agent` с любой страницы сервиса, страница-источник передаёт контекст через query-параметры URL: `objectType`, `objectId`, `objectName`, `envId`, `route`. Страница `/agent` читает параметры в `onMount` и формирует структурированный JSON-объект `UIContext`, который передаётся агенту при отправке сообщений. +- **AGCTX-FR-002**: The agent backend MUST receive the UIContext JSON and inject it into the system prompt / runtime context block in a machine-and-human-readable format, distinguishable from user message text. +- **AGCTX-FR-003**: Context is static for the duration of a `/agent` page visit. If the user navigates away and returns, fresh context is derived from new URL parameters. EnvId may be updated during the visit via EnvSelector (`updateActiveEnv`), which synchronises both the model atom and the envId sent with subsequent messages. +- **AGCTX-FR-004**: The UIContext payload MUST be versioned (`contextVersion` field, currently 1). Backend MUST validate: `objectType` enum (`"dashboard"|"dataset"|"migration"`), `objectId` format (numeric string or null), `envId` against known environments, max field lengths (objectName ≤ 256 chars), max payload size (4 KB malformed/oversized context MUST trigger a 422 error or be silently discarded with audit logging — never silently injected into the LLM prompt. +- **AGCTX-FR-005**: The agent backend MUST **hard-filter** (exclude, not deprioritise) the tool list by `objectType`: dashboard-oriented tools for dashboard context, dataset-oriented tools for dataset context, full tool set when `objectType` is null/absent. `show_capabilities` always included. + +- **AGGRD-FR-001**: Guardrails risk classification MUST consider the target environment (`prod` vs `staging` vs `dev`) in addition to the tool name prefix. +- **AGGRD-FR-002**: The confirmation card UI MUST display environment context (badge, tone) and distinguish read vs write operations visually. +- **AGGRD-FR-003**: Permission-denied tool calls MUST be rejected server-side before confirmation is presented — the card shows «access denied» without a confirm button. +- **AGGRD-FR-004**: Cancelled confirmations MUST produce an explicit «operation cancelled» message in the chat stream. + +- **AGTL-FR-001**: Tool availability MUST be filtered by user role — write tools excluded for read-only roles. +- **AGTL-FR-002**: Read-only tool HTTP calls MUST retry once with a fixed 1-second delay on transient errors (5xx, connection errors). Write/mutating tools MUST NOT auto-retry — raises immediately. +- **AGTL-FR-003**: Large tool responses (>4000 chars) MUST be structured-truncated (top-N items + total count for arrays; sentence-boundary truncation for text) rather than hard-truncated mid-structure. +- **AGTL-FR-004**: Tool execution MUST have a configurable timeout (default 30s); hanging calls MUST return a timeout error rather than block the chat. For write/mutating tools, timeout MUST produce «operation status unknown — check status» rather than automatic retry, as the backend mutation may have succeeded despite the timeout. +- **AGTL-FR-005**: Tool RBAC filtering MUST be enforced at TWO layers: (a) prompt-level — excluded tools are not presented to the LLM; (b) invocation-level — before executing any tool, the backend MUST validate the tool name against the user's role permissions even if it was filtered from the prompt. Rejected invocations emit `permission_denied` SSE event, not `confirm_required`. +- **AGTL-FR-006**: Embedding-based tool router integration (existing `_embedding_router.py`) is a SHOULD enhancement for post-MVP. When active, it restricts the tool list to top-K semantically relevant tools. Not required for initial release. + +### Key Entities + +- **UIContext**: Structured JSON payload assembled by the frontend from URL query parameters at `/agent` page entry. Contains: `objectType` (`"dashboard"`|`"dataset"`|`"migration"`|`null`), `objectId` (string|null), `objectName` (string|null, max 256 chars), `envId` (string|null), `route` (string — source page route), `contextVersion` (number, currently 1). Static for the duration of the `/agent` visit. EnvId may be updated mid-visit via `updateActiveEnv`. Бэкенд валидирует все поля перед инжекцией в промпт. +- **ContextToolAffinity**: Server-side mapping from `objectType` → set of relevant tool operations. Used to prioritise/filter tools for the LLM. Example: `dashboard` → `[search_dashboards, get_health_summary, deploy_dashboard, run_llm_validation, ...]`; `dataset` → `[superset_explore_database, superset_format_sql, superset_audit_permissions, ...]`; `none` → all available tools. +- **GuardrailDecision**: Result of server-side guardrail evaluation. Contains: risk level (safe/guarded/dangerous), risk tone (success/warning/destructive), environment context, permission check result, recommended confirmation prompt. Used to render the confirmation card. +- **ToolPermission**: Mapping of tool operation → required role(s). Derived from the `@assistant_tool` decorator's `permission_checks` (ADR-0008). Used to filter the LLM's available tool set per user. +- **ToolResponseSummary**: Structured summary of a large tool response. Contains: result count, top-N items (trimmed), summary text, total items indicator. Generated server-side before the response enters the LLM context window. + +## Success Criteria + +- **SC-001**: Агент, получивший контекст дашборда через `/agent?objectType=dashboard&objectId=42&envId=ss-dev`, в 100% тестовых сценариев правильно идентифицирует дашборд (id=42) и использует только дашборд-ориентированные инструменты — измерено через интеграционный тест с заданным контекстом. +- **SC-002**: Guardrails card renders with correct risk classification (read/write/dangerous + environment context) within 200ms of confirmation trigger — measured via browser performance API. +- **SC-003**: Tool invocation errors from transient FastAPI failures decrease by 50% relative to current baseline — измерено через structured audit log comparison за 1 week of operation after deployment. +- **SC-004**: Average tool response size entering the LLM context window decreases by 30% — measured via log analysis of response summarisation calls over 1 week of operation. +- **SC-005**: Zero cases where an `analyst`-role user can invoke a write tool (git deploy, dashboard migration, etc.) — verified via RBAC integration test at both prompt-filtering and invocation-enforcement layers. +- **SC-006**: 100% of malformed/oversized UIContext payloads are rejected or discarded with audit logging — verified via fuzzing test. + +#endregion FeatureSpec diff --git a/specs/035-agent-chat-context/tasks.md b/specs/035-agent-chat-context/tasks.md new file mode 100644 index 00000000..746c6656 --- /dev/null +++ b/specs/035-agent-chat-context/tasks.md @@ -0,0 +1,240 @@ +#region Tasks [C:3] [TYPE ADR] [SEMANTICS tasks,implementation,agent-chat] +@defgroup Tasks Implementation tasks for 035-agent-chat-context v2 — Path B model with /agent page, two-layer RBAC, permission_denied flow, and structured truncation. + +**Input**: Design documents from `/specs/035-agent-chat-context/` +**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, data-model.md ✅, contracts/modules.md ✅ + +## Format: `[ID] [P?] [Story] Description` + +--- + +## Phase 1: Setup + +- [ ] T001 [P] Materialize API fixtures from `specs/035-agent-chat-context/fixtures/api/` into `backend/tests/fixtures/agent/` +- [ ] T002 [P] Materialize model fixtures from `specs/035-agent-chat-context/fixtures/model/` into `frontend/src/lib/models/__fixtures__/agent/` +- [ ] T003 Verify toolchain: `cd backend && source .venv/bin/activate && python -m pytest --co -q`, `cd frontend && npm run test -- --run` + +--- + +## Phase 2: Foundational + +- [ ] T004 [P] Define UIContext, ConfirmMetadataV2, PermissionDeniedMetadata, extended ToolCall in `frontend/src/lib/models/AgentChatTypes.ts` + @POST: UIContext with objectType, objectId, objectName(string|null max 256), envId, route, contextVersion(1) + @POST: PermissionDeniedMetadata {type, tool_name, required_role, user_role, alternatives} + @POST: ToolCallStatus extended with "retrying"|"timeout"|"cancelled"; ToolCall +isWriteTool? + +- [ ] T005 [P] Create `backend/src/agent/_context.py` — UIContext validation + @POST: validate_uicontext(payload) → validated dict or ValidationError + @TEST_EDGE: valid→returns, invalid_objectType→422, oversized>4KB→413, objectName>256→422 + +- [ ] T006 Create `backend/src/agent/_tool_filter.py` — tool selection pipeline + invocation guard + @POST: build_tool_pipeline(tools, user_role, object_type) → filtered list.
