In the Grammarly API error tracking logic, what exact metric name is incremented when an exception occurs, and what tags are attached?
| Checked | Without skill | With skill |
|---|---|---|
| Increments metric name 'grammarly.api.errors'. | Missed | Passed |
| Tags the error counter with the HTTP status code. | Missed | Passed |
The instructions your model reads when the skill loads.
Grammarly API integrations process user text through scoring, AI rewriting, and plagiarism endpoints where latency and accuracy directly affect user experience. Monitor text check response times, suggestion quality signals, API error rates, and token consumption to stay within rate limits. Catching degradation early prevents users from seeing stale suggestions or silent failures in real-time editing flows.
| Metric | Type | Target | Alert Threshold |
|---|---|---|---|
| Text check latency p95 | Histogram | < 300ms | > 800ms |
| API error rate | Gauge | < 1% | > 5% |
| Suggestion acceptance rate | Gauge | > 40% | < 20% (quality signal) |
| Token usage (daily) | Counter | < 80% quota | > 90% quota |
| Plagiarism check latency | Histogram | < 2s | > 5s |
| AI rewrite throughput | Counter | Stable | Drop > 30% |
