API Error And Latency Monitor

text
Add Telemetry to API request handling.

Use /skill.md and this Telemetry API key: YOUR_API_KEY

Log each important API request with:
route_template, method, status_code, status, latency_ms, user_id, team_id, request_size_bytes, response_size_bytes, error_type, and feature.

Create charts for request volume, error rate, p50 latency, p95 latency, and top failing endpoints. Add alerts for 5xx spikes, slow p95 latency, and traffic drops.

Do not log request bodies, cookies, auth headers, secrets, or raw user content.
