Skills
Request Logging
Logs every prompt, completion, cost and latency figure through a proxy or async API with a one-line change.
Caching And Rate Limits
Caches repeated completions and enforces per-user rate limits at the gateway to cut spend and abuse.
Session Tracing
Groups multi-step agent calls into sessions so a whole run can be replayed and debugged as one unit.
