Validating Project
Auto-detect project tooling and run validation steps in the correct order.
Process
- Check
./CLAUDE.mdfor validation tools and project permissions - Auto-detect project type if needed (package.json, pyproject.toml, Cargo.toml, Makefile, go.mod)
- Run validation pipeline: Format -> Lint -> Type Check -> Test
- Stop immediately on failures
- Report results
Tool Commands by Project Type
Make-based (check first -- overrides everything)
make format && make lint && make typecheck && make test
Or make validate if available.
Python
uv run ruff format .
uv run ruff check .
uv run ty check # or uv run mypy, uv run pyright
uv run pytest
Node.js / TypeScript
pnpm run format # or npx prettier --write .
pnpm run lint # or npx eslint .
pnpm run typecheck # or npx tsc --noEmit
pnpm test
Rust
cargo fmt
cargo clippy
cargo test
Go
gofmt -w .
go vet ./...
go test ./...
Auto-Discovery Logic
# Priority order
if [ -f "Makefile" ]; then
# Check for make validate/format/lint/test targets
elif [ -f "pyproject.toml" ]; then
# Python -- check for uv, poetry
elif [ -f "package.json" ]; then
# Node.js -- check for pnpm, npm, yarn
elif [ -f "Cargo.toml" ]; then
# Rust
elif [ -f "go.mod" ]; then
# Go
fi
Error Handling
- Tool not found: Provide installation instructions
- Configuration missing: Suggest minimal setup
- Validation failures: Show specific fix recommendations
- Dependency conflicts: Suggest resolution strategies
