Verify Feature

Verify Feature

Post-implementation browser verification for frontend features. Auto-detects changed routes from git history, navigates them, takes screenshots, and checks for console/network errors.

Arguments

• {route} — Route to verify (e.g., /users, /settings). If omitted, auto-detects from git changes.
• --responsive — Also capture mobile viewport screenshots (375x667)
• --interactive — Click the first Create/Add button, verify dialog appears, then dismiss

Configuration

Read cloudstack.json from the project root at the start of execution. Extract:

• FRONTEND_PATH = frontend.path (default: web)
• DEV_PORT = frontend.devPort (default: 5173)
• UI_LIBRARY = frontend.uiLibrary (default: shadcn)
• STATE_SERVER = frontend.stateManagement.server (default: tanstack-query)
• STATE_CLIENT = frontend.stateManagement.client (default: zustand)
• MULTI_TENANT = backend.multiTenancy (default: false)

If cloudstack.json does not exist, auto-detect by checking package.json dependencies.

Auth Configuration

Check cloudstack.json for localDev.authConfig. If present, use it for localStorage injection. Otherwise, detect the auth store pattern from the codebase (see screenshot skill for details).

Process

Step 1: Detect Routes

If a route was provided, use it directly. Otherwise, auto-detect from recent changes:

# Find changed page files
git diff --name-only HEAD~3 | grep "{FRONTEND_PATH}/src/.*pages/"

Map changed page files to routes by finding the router configuration file:

# Find router config
grep -rl "createBrowserRouter\|RouteObject\|/dev/null | head -3

Read the router file and match feature/page names to route paths.

If no routes can be detected, ask the user which route to verify.

Step 2: Pre-flight

curl -sf http://localhost:{DEV_PORT} > /dev/null 2>&1 && echo "Frontend: UP" || echo "Frontend: DOWN"

If frontend is down, STOP and suggest starting the dev server.

Step 3: Authenticate

Navigate to http://localhost:{DEV_PORT} to establish the origin, then inject auth via localStorage using the auth configuration (from cloudstack.json or auto-detected from the codebase).

Step 4: Verify Each Route

For each detected route:

1. Navigate — browser_navigate to http://localhost:{DEV_PORT}{route}
2. Wait — browser_wait_for for content to load (network idle or 3 seconds)
3. Snapshot — browser_snapshot to check accessibility tree for meaningful content (not just a loading spinner or error boundary)
4. Console — browser_console_messages to flag any error level messages
5. Network — browser_network_requests to flag 4xx/5xx responses
6. Screenshot — browser_take_screenshot (always)

Step 5: Responsive Check (if --responsive)

For each route:

1. browser_resize to 375, 667
2. browser_take_screenshot — mobile viewport
3. browser_resize to 1280, 720 — restore desktop

Step 6: Interactive Check (if --interactive)

For each route:

1. browser_snapshot to find clickable Create/Add/New buttons
2. If found: browser_click on the first one
3. browser_wait_for a dialog or form to appear (2 seconds)
4. browser_snapshot to verify the dialog rendered
5. browser_click on close/cancel or browser_evaluate to press Escape:

``javascript document.dispatchEvent(new KeyboardEvent('keydown', { key: 'Escape' })) ``

Step 7: Cleanup

browser_close to end the session.

Output Format

## Feature Verification: {route(s)}

### Route Checks
| Route | Content | Console | Network | Screenshot |
|-------|---------|---------|---------|------------|
| /users | PASS | PASS (0 errors) | PASS (all 2xx) | captured |
| /users/:id | FAIL | FAIL (1 error) | PASS | captured |

### Console Errors
- `/users/:id`: `TypeError: Cannot read property 'name' of undefined` at user-detail.tsx:28

### Network Issues
- None

### Responsive (if --responsive)
| Route | Mobile Screenshot | Issues |
|-------|-------------------|--------|
| /users | captured | None |

### Interactive (if --interactive)
| Route | Button Found | Dialog Opened | Dialog Closed |
|-------|-------------|---------------|---------------|
| /users | "Create User" | PASS | PASS |

### Summary: {PASS / FAIL}

Error Handling

• Frontend not running: STOP and suggest starting the dev server.
• No routes detected: Ask the user which route to verify.
• Auth redirect: If a page redirects to /login after auth injection, retry auth once with a full page reload.
• Empty content: If snapshot shows only a loading spinner after 5 seconds, report as FAIL with note.
