Purpose

Quality Gates Skill

Automated quality checkpoints that ensure code meets standards before proceeding.

Gate Levels

1. Pre-Commit Gate

Runs before code is committed.

# TypeScript check
npx tsc --noEmit

# Lint check
npx eslint . --max-warnings 0

# Format check
npx prettier --check .

2. Pre-Push Gate

Runs before code is pushed.

# All pre-commit checks +
npm test -- --passWithNoTests

# Build check
npm run build

3. CI Gate

Runs in CI pipeline.

# All previous checks +
npm test -- --coverage

# Coverage threshold
# Fail if coverage < 70%

4. Pre-Deployment Gate

Runs before deployment.

# All CI checks +
# E2E tests
npx playwright test

# Security audit
npm audit --audit-level=high

# Performance check
npx lighthouse-ci

    "noImplicitAny": true,
    "strictNullChecks": true,

}

Pass Criteria: Zero errors, zero warnings

Prettier Gate

// .prettierrc
{
  "semi": true,
  "singleQuote": true,
  "tabWidth": 2,
  "trailingComma": "es5"

Pass Criteria: All files formatted

Test Gate

// vitest.config.ts
export default defineConfig({
  test: {
    coverage: {
      provider: 'v8',
      thresholds: {
        statements: 70,
        branches: 65,
        functions: 70,
        lines: 70,
      },
    },
  },
});

Pass Criteria:

• All tests pass
