Collect Grammarly API connectivity status, text analysis response quality, authentication state, and rate limit usage into a single diagnostic archive. This bundle helps troubleshoot text check failures, missing suggestions, OAuth token expiration, and API response latency.

| Symptom | Check in Bundle | Fix |
|---|---|---|
| API returns 401 | summary.txt shows HTTP 401 |
Refresh OAuth token or regenerate API key in Grammarly Developer Hub |
| Zero suggestions returned | text-check.json has empty alerts array |
Verify text exceeds minimum word count (30 words); check language parameter |
| High latency (>5s) | text-check.json shows slow response time |
Reduce text payload size; check for network proxy interference |
| Rate limited (429) | rate-headers.txt shows Retry-After |
Implement request queuing; reduce check frequency per user session |
| Client ID mismatch | account.json returns permission error |
Verify GRAMMARLY_CLIENT_ID matches the app registered in Developer Hub |
