Run Project Checks

Context

• Project type detection: !ls package.json Makefile pyproject.toml Cargo.toml go.mod 2>/dev/null || echo "No standard project files found"
• Current directory: !pwd

Your task

Execute project quality checks. Identify the project type and run appropriate checks.

Arguments

• --test: Run tests only
• --lint: Run linter only
• --format: Run formatter only
• --build: Run build only
• --all or no args: Run all checks (format → lint → build → test)

Steps

1. Detect project type by checking for config files:

   • package.json → Node.js
   • go.mod → Go
   • Cargo.toml → Rust
   • pyproject.toml / setup.cfg → Python
   • Makefile → Make-based

2. Run checks in order (for --all):

   • Formatter (auto-fix first)
   • Linter (catch issues)
   • Build (compile check)
   • Tests (verify functionality)

Commands by Language

Go

# Format
gofmt -w .
goimports -w .  # if available

# Lint
go vet ./...
golangci-lint run  # if available
staticcheck ./...  # if available

# Build
go build ./...

# Test
go test ./...
go test -race ./...  # with race detection
go test -cover ./... # with coverage

JavaScript/TypeScript (Node.js)

# Format
npm run format || npx prettier --write .

# Lint
npm run lint || npx eslint .

# Type Check
npm run typecheck || npx tsc --noEmit

# Build
npm run build

# Test
npm test

Rust

# Format

Output Format

## Quality Check Results

### Format
✓ PASSED (or ✗ FAILED with details)

### Lint
✓ PASSED (or ✗ FAILED with details)

### Build
✓ PASSED (or ✗ FAILED with details)

### Test
✓ PASSED: X tests passed
(or ✗ FAILED: X passed, Y failed)

---
Overall: PASSED / FAILED

Integration with /impl

When called from /impl:

• --test is commonly used during RED/GREEN/REFACTOR cycles
• Full checks (--all) run at phase completion

Notes

• Run formatter before linter to auto-fix issues
• If a check fails, report the error and stop (for --all mode)
• Check project's README for specific instructions
• For CI alignment, ensure local checks match pipeline
