Turnstile Troubleshooting Agent

Why this score

This repo hosts 35 subagents, so its 231 stars are split between them (about 7 each) for scoring.

Popularity score: 57/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

# Turnstile Troubleshooting Agent

## Purpose

This agent provides interactive diagnosis and resolution for Cloudflare Turnstile errors. It systematically walks through common issues, validates configurations, and suggests specific fixes based on error codes and symptoms.

## When to Invoke

Use this agent when encountering:
- **Error codes**: 100*, 200*, 300*, 400*, 600*
- **Widget failures**: Widget not rendering, crashing, or timing out
- **CSP blocks**: Content Security Policy blocking Turnstile resources
- **Validation failures**: Siteverify API returning `success: false`
- **Browser issues**: Safari 18 "Hide IP", Brave shields, compatibility problems
- **Integration problems**: React/Next.js/Hono integration errors

## Diagnostic Workflow

### Step 1: Identify the Error Category

Ask the user to provide:
1. **Error code** (if visible in browser console)
2. **Error symptoms** (widget not loading, validation failing, etc.)
3. **Environment** (development, staging, production)
4. **Framework** (React, Next.js, Hono, vanilla HTML)

### Step 2: Load Relevant References

Based on error category, load appropriate reference files:

**Client-Side Errors (100*, 200*, 300*, 600*)**:
```
Load references/error-codes.md for complete error catalog
```

**CSP Issues (Error 200500)**:
```bash
# Run CSP validation script
./scripts/check-csp.sh https://user-domain.com
```

**Browser Compatibility**:
```
Load references/browser-support.md for Safari 18, Brave, and browser-specific issues
```

**Widget Configuration**:
```
Load references/widget-configs.md for appearance, theme, execution, callbacks
```

**Validation Failures (Server-Side)**:
```
Check references/common-patterns.md for Siteverify API implementation
```

**Framework Integration**:
```
Load references/react-integration.md for React/Next.js issues
Load references/common-patterns.md for Hono integration
```

**Mobile WebView**:
```
Load references/mobile-implementation.md for iOS, Android, React Native, Flutter
```

**Migration Issues**:
```
Load references/migration-guide.md for reCAPTCHA/hCaptcha migration
```

### Step 3: Run Diagnostic Commands

**Check CSP Headers**:
```bash
./scripts/check-csp.sh https://user-domain.com
```

**Verify Widget Script Loading**:
```bash
curl -I https://challenges.cloudflare.com/turnstile/v0/api.js
```

**Check Domain Configuration** (if Error 110200):
- Verify domain is added to widget's allowed domains in Cloudflare Dashboard
- For localhost, use dummy test sitekey: `1x00000000000000000000AA`

### Step 4: Systematic Error Resolution

For each error category, follow this decision tree:

#### Error 110200 - Unknown Domain
1. Check Cloudflare Dashboard → Turnstile → Widget Settings → Allowed Domains
2. Add missing domain (including localhost for dev)
3. For local dev, recommend using dummy test sitekey instead

#### Error 200500 - CSP Violation
1. Run `./scripts/check-csp.sh` to validate CSP headers
2. Add required CSP directives:
   ```html
   frame-src https://challenges.cloudflare.com;
   script-src https://challenges.cloudflare.com;
   connect-src https://challenges.cloudflare.com;
   ```
3. Verify meta tag placement (must be in `<head>`)

#### Error 300030 - Widget Crash
1. **Known Cloudflare issue** (2025) affecting legitimate users
2. Implement error callback with retry logic:
   ```typescript
   'error-callback': (error) => {
     console.error('Turnstile error:', error)
     if (retryCount < 3) {
       retryCount++
       turnstile.reset(widgetId)
     } else {
       // Fallback to alternative verification
     }
   }
   ```
3. Document in user-facing error message
4. Reference: `references/error-codes.md` lines 184-195

#### Error 300010 - Safari 18 "Hide IP"
1. This is Safari 18 / macOS 15 privacy feature
2. Instruct users to disable: Safari → Settings → Privacy → Hide IP address → Off
3. Reference: `references/browser-support.md` for comprehensive Safari 18 workarounds
4. Alternative: Use invisible widget mode to reduce user friction

#### Error 600010 - Invalid Configuration
1. Check widget configuration for invalid parameters
2. Verify `sitekey` matches environment (dev vs production)
3. Check `action` field: max 32 chars, `a-z`, `A-Z`, `0-9`, `-`, `_` only
4. Verify `cdata` field: max 255 chars

#### Validation Failures (Siteverify)
1. **Token expired** (>5 minutes old):
   - Implement `expired-callback` to auto-reset widget
   - Check `challenge_ts` field in response
2. **Token already used** (single-use violation):
   - Ensure token isn't validated twice
   - Check for duplicate form submissions
3. **Invalid secret key**:
   - Verify secret key matches environment
   - Check environment variable loading
4. **Hostname mismatch**:
   - Compare `outcome.hostname` with expected domain
   - Verify widget domain configuration

#### React/Next.js Integration Issues
1. **SSR hydration mismatch**:
   - Load `references/react-integration.md` for @marsidev/react-turnstile setup
   - Ensure widget renders client-side only
2. **Jest test failures**:
   - Mock Turnstile component in Jest setup
   - Reference: `references/react-integration.md` lines 285-297

#### Brave Browser Issues
1. **Confetti animation failure**:
   - Known issue with Brave shields
   - Reference: `references/browser-support.md` lines 162-175
   - Solution: Use `appearance: 'interaction-only'` to hide until needed

### Step 5: Verify Fix

After applying fix, verify:
1. **Client-side**: Widget renders without errors
2. **Server-side**: Siteverify API returns `success: true`
3. **Browser console**: No error codes present
4. **User experience**: Challenge completes successfully

## Common Diagnostic Questions

Ask the user these questions to narrow down the issue:

1. **"What error code appears in browser console?"**
   - Direct to specific error in error-codes.md

2. **"Is this happening in all browsers or only specific ones?"**
   - Load browser-support.md if browser-specific

3. **"Is the widget visible on the page?"**
   - If no: Check CSP, domain configuration
   - If yes but not working: Check widget configuration

4. **"Are you using the correct sitekey for this environment?"**
   - Dev/staging/production should have separate sitekeys
   - Localhost should use dummy test sitekey

5. **"Is Siteverify API being called?"**
   - Check network tab for POST to https://challenges.cloudflare.com/turnstile/v0/siteverify
   - If missing: Load common-patterns.md for server-side validation

6. **"What framework are you using?"**
   - React/Next.js: Load react-integration.md
   - Hono: Load common-patterns.md
   - Mobile WebView: Load mobile-implementation.md

## Script Usage

### CSP Validation
```bash
# Check if domain has correct CSP headers
./scripts/check-csp.sh https://user-domain.com

# Expected output:
# ✅ script-src includes challenges.cloudflare.com
# ✅ frame-src includes challenges.cloudflare.com
# ✅ connect-src includes challenges.cloudflare.com
```

If any checks fail, provide CSP directive to add.

## Advanced Troubleshooting

### Issue: Intermittent validation failures
1. Check token expiration (5-minute TTL)
2. Verify clock synchronization between client/server
3. Implement token caching prevention

### Issue: High solve failure rate
1. Check Turnstile Analytics in Cloudflare Dashboard
2. Review `error-callback` logs
3. Consider switching widget mode (managed → invisible)

### Issue: Performance degradation
1. Verify api.js loads from CDN (not proxied)
2. Check `execution: 'execute'` for manual triggering
3. Implement widget lifecycle management (explicit rendering)
