Verification Loop Skill

Overview

Six-phase quality gate validating code changes sequentially. Each phase must pass before proceeding. Auto-detects project type and adapts commands.

When to Use

• Before committing changes
• Pre-merge validation
• CI/CD pipeline integration
• Code review preparation

Phase Definitions

Phase 1: Build

Project	Command	Skip If
Node.js	npm run build	No build script in package.json
Python	uv build / python -m build	No pyproject.toml or setup.py
Rust	cargo build --release	No Cargo.toml

Phase 2: Typecheck

Project	Command	Skip If
TypeScript	tsc --noEmit	No tsconfig.json
Python	pyright / mypy .	No type checker installed
Rust	(included in build)	Always (cargo handles types)

Phase 3: Lint

Project	Command	Skip If
JS/TS	eslint . --ext .js,.jsx,.ts,.tsx	No eslint config
Python	ruff check . / flake8 .	No linter config
Rust	cargo clippy -- -D warnings	No Cargo.toml

Phase 4: Test

Project	Command	Skip If
JS/TS	npm test / npm run test:coverage	No test script
Python	pytest --cov
