+# 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
+
+### Phase 1: Build Verification
+```bash
+# Check if project builds
+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
+```bash
+# 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
+```bash
+# JavaScript/TypeScript
+npm run lint 2>&1 | head -30
+
+# Python
+ruff check . 2>&1 | head -30
+```
+
+### Phase 4: Test Suite
+```bash
+# Run tests with coverage
+npm run test -- --coverage 2>&1 | tail -50
+
+# Check coverage threshold
+# Target: 80% minimum
+```
+
+Report:
+- Total tests: X
+- Passed: X
+- Failed: X
+- Coverage: X%
+
+### Phase 5: Security Scan
+```bash
+# Check for secrets
+grep -rn "sk-" --include="*.ts" --include="*.js" . 2>/dev/null | head -10
+grep -rn "api_key" --include="*.ts" --include="*.js" . 2>/dev/null | head -10
+
+# Check for console.log
+grep -rn "console.log" --include="*.ts" --include="*.tsx" src/ 2>/dev/null | head -10
+```
+
+### Phase 6: Diff Review
+```bash
+# Show what changed
+git diff --stat
+git diff HEAD~1 --name-only
+```
+
+Review each changed file for:
+- Unintended changes
+- Missing error handling
+- Potential edge cases
+
+## Output Format
+
+After running all phases, produce a verification report:
+
+```
+VERIFICATION REPORT
+==================
+
+Build:     [PASS/FAIL]
+Types:     [PASS/FAIL] (X errors)
+Lint:      [PASS/FAIL] (X warnings)
+Tests:     [PASS/FAIL] (X/Y passed, Z% coverage)
+Security:  [PASS/FAIL] (X issues)
+Diff:      [X files changed]
+
+Overall:   [READY/NOT READY] for PR
+
+Issues to Fix:
+1. ...
+2. ...
+```
+
+## Continuous Mode
+
+For long sessions, run verification every 15 minutes or after major changes:
+
+```markdown
+Set a mental checkpoint:
+- After completing each function
+- After finishing a component
+- Before moving to next task
+
+Run: /verify
+```
+
+## Integration with Hooks
+
+This skill complements PostToolUse hooks but provides deeper verification.
+Hooks catch issues immediately; this skill provides comprehensive review.
