# Agent Fleet Observability Desk ## Overview Kelly Agent Observability is a Busabase Cloud App-in-Skill. Its canonical product surface is the AirApp in Busabase, not a separate local-data product. The same Hono source supports an explicitly requested local preview with OAuth connection bootstrap. It gives an operator a read-mostly dashboard over a MOCK fleet of LLM agents running behind a shared AI gateway for a generic organization: per-agent call volume, latency (p50/p95), error/failure rate, cost, an hourly call-volume sparkline, and a Trace Detail view that highlights exactly where a chain of tool calls broke. This skill was never a live monitoring integration, even before this conversion — there is no real gateway, no real agents, and no real telemetry anywhere. The fleet snapshot (agents + metrics + traces) is generated by a deterministic, seeded function and written into Busabase by a trusted skill-root script (`scripts/generate_fleet_data.mjs`); the AirApp itself only ever **reads** whatever was last generated there. The only human action is narrow: append an "acknowledge" / "needs investigation" handoff note to an agent or trace — always a brand-new row in the `handoffs` Base, never a field update on the agent/trace's own record. Default behavior is AirApp-first. Unless the user explicitly asks only for explanation, ensure the mock fleet exists (run the seed script below if the `agents` Base is empty) and give the user the clickable AirApp URL.
