Verification Loop

Verification Loop Skill

A comprehensive verification system for Claude Code sessions.

When to Use

Invoke this skill:

• After completing a feature or significant code change
• Before creating a PR
• When you want to ensure quality gates pass
• After refactoring

Verification Phases

Choose the commands adaptively for the current project instead of running every example blindly. Use the stack-appropriate command from references/STACK-DETECTION.md when the repo does not match the default examples below.

Phase 1: Build Verification

# Python projects (uv)
uv build 2>&1 | tail -20
# OR
python -m build 2>&1 | tail -20

# Node.js projects
npm run build 2>&1 | tail -20
# OR
pnpm build 2>&1 | tail -20

If build fails, STOP and fix before continuing.

Phase 2: Type Check

# TypeScript projects
npx tsc --noEmit 2>&1 | head -30

# Python projects
pyright . 2>&1 | head -30

Report all type errors. Fix critical ones before continuing.

Phase 3: Lint Check

# JavaScript/TypeScript
npm run lint 2>&1 | head -30

# Python
ruff check . 2>&1 | head -30
