Build & Development Commands

This project uses uv for Python and pnpm for the dashboard frontend (dashboard/).

# Backend
uv run ruff check --fix amelia tests   # Lint (auto-fix)
uv run mypy amelia                     # Type check
uv run pytest                          # Full test suite
uv run pytest tests/unit/              # Unit tests only

# Dashboard (run from dashboard/)
pnpm build        # Production build
pnpm test:run     # Tests (CI mode)
pnpm lint:fix     # ESLint auto-fix
pnpm type-check   # TypeScript checking

# Full stack
uv run amelia dev                      # API on :8420, dashboard on :8421

Pre-push hook runs ruff check, mypy, pytest, and pnpm build — all must pass.

Code Conventions

• Test-Driven Development (TDD) — write tests first, then implementation
• Python 3.12+ with type hints everywhere
• Pydantic models for all data structures — not ad-hoc dicts
• Async throughout — avoid blocking calls in async functions
• Loguru for logging (logger), not print. Use kwargs for structured fields: logger.info("msg", key=value)
• Typer for CLI with annotated parameters
• Raise ValueError with clear messages for validation failures
• New drivers/agents must conform to interfaces in amelia/core/

Test Conventions

Tests use pytest-asyncio with asyncio_mode = "auto".

• DRY — extract common setup into fixtures in tests/conftest.py
• Integration tests (tests/integration/) must use real components — only mock at the external boundary (e.g., HTTP calls to LLM APIs). Never mock internal classes like Architect, Developer, or Reviewer. If you're patching internals, it's a unit test — put it in tests/unit/.
• High-fidelity mocks — return the same types production code returns (e.g., Pydantic model instances, not .model_dump() dicts)

Browser Automation

Use agent-browser for web automation: agent-browser open <url>, then agent-browser snapshot -i for interactive element refs, then agent-browser click @e1 / agent-browser fill @e2 "text".
