Project Setup & Configuration Skill

This skill outlines the standard procedure for setting up and maintaining the kitchen project environment. It mandates specific tools for dependency management, task running, and code quality.

1. Directory Structure

• •docs/: Documentation root.
  • •docs/plans/: Active planning documents and specifications.
  • •docs/plans/decisions/: Architecture Decision Records (ADRs).
• •src/: Source code.
  • •src/api/: Python FastAPI backend.
  • •src/mobile/: React Native (Expo) frontend.
• •tests/: Test suites.
  • •tests/api/: Backend unit/integration tests (pytest).
  • •tests/web/: Frontend E2E tests (Playwright).
• •infra/docker/: Docker Compose configuration and volume templates.
• •phase0_flow/: Legacy recipe data and PDF generation (Phase 0).
• •scripts/: Utility scripts (e.g., mermaid linting).

2. Tooling Stack

• •Task Runner: just - The primary entry point for all developer tasks.
• •Python Management: uv - Fast package installer and resolver.
• •Node/JS Management: npm - Used for frontend dependencies and documentation tools.
• •Process Manager: hivemind - For running full-stack development environment (via Procfile.dev).
• •Environment Management: .mise.toml - Manages tool versions (python, node, uv).

3. Configuration Files

pyproject.toml (Python)

Configures ruff (linting/formatting), pytest (testing), and mypy (type checking).

[tool.pytest.ini_options]
testpaths = ["tests"]
pythonpath = ["."]
asyncio_mode = "auto"
# Strict warnings policy
filterwarnings = ["error", "ignore::DeprecationWarning:hypothesis.*"]

[tool.ruff]
line-length = 100
target-version = "py313"

[tool.ruff.lint]
select = ["E", "W", "F", "I", "B", "C4", "UP", "ARG", "SIM"]
ignore = ["E501", "B008", "ARG002"] # ARG002 allows unused args in interfaces

[tool.mypy]
python_version = "3.13"
plugins = ["pydantic.mypy"]
disallow_untyped_defs = true # Strict typing

package.json (Root)

Handles markdown linting and diagram validation.

{
  "scripts": {
    "lint": "markdownlint '**/*.md' --ignore '**/node_modules/**'"
  }
}

justfile (Key Commands)

Use just <command> for all common tasks.

• •Setup: just setup (installs all python/js dependencies).
• •Dev (Full Stack): just dev-all (starts API, DB, and Frontend via Hivemind).
• •Dev (Frontend): just web (starts Expo web).
• •Dev (Backend): just dev-api (starts FastAPI with reload).
• •Infrastructure: just up (starts Docker stack), just down (stops it).
• •Quality: just check (runs lint, test, and typecheck).
• •Testing: just test (all), just test-py (backend), just test-e2e (frontend).

4. Workflow Standards

Development Loop

1. •Start Infra: just up-infra (or just dev-all for full stack).
2. •Code: Make changes in src/.
3. •Verify: Run just check before committing. This enforces:
   • •Linting: ruff (Python), markdownlint (Docs), lint_mermaid.py (Diagrams).
   • •Formatting: ruff format.
   • •Type Checking: mypy (Strict mode).
   • •Tests: pytest (Backend).

Database Management

• •Supabase Studio: Access local admin UI via just studio (http://localhost:5303).
• •Reset: just reset-stack wipes the database and restarts containers (Use with caution).

Documentation

• •Linting: All markdown files are linted. Mermaid diagrams within markdown are validated.
• •Structure: Keep the root clean. New documentation goes into docs/.
