Agent tracing is how you stop guessing.
A useful trace answers:
- Which agent and tools ran
- Inputs/outputs at tool boundaries (with redaction discipline)
- Failures and retries
- Cost signals (tokens, time)
Tracing vs marketing dashboards
A green "uptime" tile is not tracing. Structured run metadata is. Production agent platforms are rediscovering this the hard way—scout runs without self-reported facts cannot answer "did this file feedback?"
Pair with token usage
Traces tell quality story; token usage tells money story. You need both for an AI-native company.
