Tasks: LLM Chat Assistant for Project Operations

Input: Design documents from /specs/021-llm-project-assistant/
Prerequisites: plan.md, spec.md, ux_reference.md, research.md, data-model.md, contracts/

Tests: Include backend contract/integration tests and frontend integration/state tests.

Organization: Tasks are grouped by user story for independent implementation and validation.

Format: [ID] [P?] [Story] Description

  • T012 Wire assistant router into backend/src/api/routes/__init__.py and backend/src/app.py
  • T013 Create frontend assistant API client in frontend/src/lib/api/assistant.js
  • T014 Verify contracts alignment between spec.md and contracts/modules.md

Checkpoint: Foundation complete; user stories can begin.

Phase 3: User Story 1 - Use chat instead of manual UI navigation (Priority: P1) 🎯 MVP

Goal: Add in-app assistant chat interface with working request/response loop.

Independent Test: Open assistant panel and complete one command-response interaction.

Tests for User Story 1

  • T015 [P] [US1] Add backend API contract tests for POST /api/assistant/messages in backend/src/api/routes/__tests__/test_assistant_api.py
  • T016 [P] [US1] Add frontend integration test for chat panel interaction in frontend/src/lib/components/assistant/__tests__/assistant_chat.integration.test.js

Implementation for User Story 1

  • T017 [US1] Implement assistant chat panel component in frontend/src/lib/components/assistant/AssistantChatPanel.svelte
  • T018 [US1] Add assistant launch trigger to top navigation in frontend/src/lib/components/layout/TopNavbar.svelte

Checkpoint: US1 independently functional and demo-ready.

Phase 4: User Story 2 - Execute core operations via natural-language commands (Priority: P1)

Goal: Support command parsing and dispatch for Git/migration/backup/LLM/status operations.

Independent Test: One command per domain executes correct backend path or returns valid error.

Implementation for User Story 2

  • T026 [US2] Implement Git command mappings in execution_adapter.py (create branch, commit, deploy)
  • T027 [US2] Implement migration/backup command mappings in execution_adapter.py via existing task creation
  • T028 [US2] Implement LLM validation/documentation command mappings in execution_adapter.py
  • T029 [US2] Implement task/report status query mappings in execution_adapter.py

Checkpoint: US2 independently functional across requested command domains.

Phase 5: User Story 3 - Safe execution with RBAC and explicit confirmations (Priority: P1)

Goal: Enforce permissions and confirmation gates for dangerous operations.

Independent Test: Unauthorized command denied; production deploy requires confirm and executes only after confirm.

Tests for User Story 3

  • T033 [P] [US3] Add backend authorization tests in backend/src/api/routes/__tests__/test_assistant_authz.py
  • T034 [P] [US3] Add backend confirmation lifecycle tests in backend/src/services/assistant/__tests__/test_confirmation_flow.py
  • T035 [P] [US3] Add frontend confirm/cancel UX tests in frontend/src/lib/components/assistant/__tests__/assistant_confirmation.integration.test.js

Implementation for User Story 3

  • T054 Run semantic map generation (python3 generate_semantic_map.py) and resolve critical issues in assistant modules

Dependencies & Execution Order

Phase Dependencies

  • Phase 1 has no dependencies.
  • Phase 2 depends on Phase 1 and blocks all user stories.
  • Phases 3-6 depend on Phase 2.
  • Phase 7 depends on completion of selected user stories.

User Story Dependency Graph

  • US1 (P1): MVP chat entrypoint.
  • US2 (P1): Command execution capabilities.
  • US3 (P1): Safety and security controls.
  • US4 (P2): Feedback and tracking depth.

Graph: US1 -> {US2, US3} -> US4

Parallel Opportunities

  • Setup fixture/i18n tasks: T002, T003, T004.
  • Foundational tasks: T006/T010 can run in parallel after T005 baseline.
  • Story tests in each phase marked [P] can run in parallel.
  • US2 domain mappings (T026-T029) can be split across developers.

Implementation Strategy

MVP First (Recommended)

  1. Complete Phase 1 + Phase 2.
  2. Complete Phase 3 (US1).
  3. Complete minimal subset of US2 for one domain (e.g., migration + status) and validate.

Incremental Delivery

  1. Deliver US1 chat shell.
  2. Add US2 command domains iteratively.
  3. Add US3 confirmation and RBAC hardening.
  4. Add US4 history/tracking refinements.
  5. Finish Phase 7 compliance and docs.

UX Preservation Rule

No task should degrade clarity or safety defined in ux_reference.md.
