name	project-setup
description	Bootstrap new projects with strong typing, linting, formatting, and testing. Supports Python, TypeScript, and other languages with research fallback.

Project Setup

Core Principles

• Strong Typing: Strict mode enabled; types catch bugs at compile time
• Strong Linting: Strict rules by default; easier to disable than add later
• Auto Formatting: Automated and consistent; no manual formatting
• Checks at Every Stage: Pre-commit hooks + CI; catch issues early
• Co-located Tests: foo.ts → foo.test.ts; obvious what's tested
• Behavior-Focused: Test what code does, not how; mock only external boundaries

Workflow

1. Check reference/ for language guide (Python, TypeScript)
2. If no guide: WebSearch "[language] project setup best practices"
3. Follow setup: typing → linting → formatting → testing → pre-commit → CI
4. For existing projects: migrate incrementally in same order

Reference Files

• reference/python.md - uv, ruff, basedpyright, pytest
• reference/typescript.md - pnpm, ESLint, Prettier, Vitest
• reference/common-patterns.md - Testing philosophy, CI patterns, security

Tool Selection

Prefer tools that are: ecosystem standard, actively maintained, strict by default, fast, well-integrated (editor + CI + pre-commit).

Quality Checklist

• Typing: Strictest mode, no any without justification
• Linting: Strict rules, warnings as errors
• Formatting: Auto-format on save + pre-commit
• Testing: Co-located tests, coverage >80%
• Pre-commit: Format, lint, type-check
• CI: Same checks + coverage reporting
• README: Setup instructions
• All checks pass on initial commit
