/verify - Unified Verification Skill

A comprehensive verification skill that chains static analysis, tests, and visual verification. Inspired by Boris Cherny's "verify-app" subagent pattern.

Trigger

• /verify - Run full verification suite
• /verify quick - Static analysis only
• /verify visual - Browser-based visual verification
• /verify [component] - Verify specific component/feature

Philosophy

"The most important thing to get great results out of Claude Code -- give Claude a way to verify its work."

— Boris Cherny, Creator of Claude Code

This skill provides that verification loop. It should be run: 1. After completing a feature 2. Before creating a PR 3. After merging from main 4. When debugging issues

Execution Protocol

Full Verification (/verify)

1. STATIC ANALYSIS
   ├── Run: npm run type-check || npx tsc --noEmit
   ├── Run: npm run lint
   └── GATE: Must pass before continuing

2. UNIT TESTS
   ├── Run: npm test
   ├── Collect: Coverage report
   └── GATE: Must pass before continuing

3. E2E TESTS (if playwright.config exists)
   ├── Run: npx playwright test
   └── GATE: Must pass before continuing

4. VISUAL VERIFICATION (using Playwright MCP)
   ├── Start dev server if not running
   ├── Navigate to key pages
   ├── Take screenshots
   ├── Check console for errors
   ├── Verify no network failures
   └── GATE: No critical issues

5. BUILD
   ├── Run: npm run build
   └── GATE: Must succeed

6. REPORT
   └── Summary of all layers

Quick Mode (/verify quick)

Only runs Layer 1 (Static Analysis).

Visual Mode (/verify visual)

Only runs Layer 5 (Visual Verification) using Playwright MCP.

Playwright MCP Integration

For visual verification, use these MCP tools:

// 1. Start by checking if dev server is running
mcp__playwright-server__browser_navigate({ url: "http://localhost:3000" })

// 2. Capture page state
mcp__playwright-server__browser_snapshot()

// 3. Check for console errors
mcp__playwright-server__browser_console_messages({ level: "error" })

// 4. Take screenshot for visual record
mcp__playwright-server__browser_take_screenshot({ filename: "verify-{timestamp}.png" })

// 5. Check network requests
mcp__playwright-server__browser_network_requests()

// 6. Navigate to key routes and repeat

Key Pages to Verify

For Next.js apps, automatically check:

• / - Homepage
• /login or /auth - Authentication (if exists)
• Key feature pages based on recent changes

Integration with Other Skills

This skill works with:

• /commit-push-pr - Run verify before creating PR
• /test-verify - Subset focused on testing
• code-reviewer subagent - Code quality checks

Automation Hook

Can be triggered automatically via Stop hook for long-running tasks:

# ~/.claude/hooks/stop/verify-on-complete.sh
# Runs /verify when Claude finishes a significant task
