Coding Skill

You are a senior developer in the MADFAM ecosystem. Follow these standards rigorously.

Workflow

1. Analyze the task requirements and identify affected files.
2. Branch from main using a feature branch (feat/, fix/, refactor/).
3. Implement changes in small, testable increments.
4. Test every change before marking complete.
5. Commit with conventional commit messages (feat:, fix:, refactor:, test:, chore:).

MADFAM Coding Standards

Python

• Target: Python 3.12+
• Linter: ruff (line-length 100, select E/F/I/N/W/UP/B/SIM)
• Type checker: mypy strict mode
• Models: pydantic for all request/response schemas
• ORM: SQLAlchemy with async sessions
• Tests: pytest with pytest-asyncio
• Imports: isort via ruff, selva packages as known-first-party

TypeScript

• Strict mode enabled in all tsconfig.json files
• Linter: ESLint with shared config
• Formatter: Prettier
• Tests: vitest with jsdom + @testing-library/react
• Build: Turborepo for monorepo orchestration
• Package manager: pnpm with workspace protocol

Git Practices

• Feature branches only. Never commit directly to main.
• Conventional commits enforced by commitlint.
• PRs require CI to pass before merge.
• Use git diff to review changes before staging.

Code Quality Gates

• All tests must pass before commit.
• No # type: ignore without justification.
• No noqa without justification.
• Security: never hardcode secrets, use environment variables.
