## Give this prompt to your agent

<Prompt>
  Use SEC API GET /v1/signals/volatility to return the SEC API volatility score with transparent factor breakdown and freshness metadata. Preserve `requestId`, `traceparent`, `provenance`, `freshness`, `methodologyVersion`, `factors`, `degradedReasons` in the output. Return a concise markdown summary plus the exact structured payload fields that a downstream engineer or agent should keep using this result.
</Prompt>

## Failure posture

* treat non-2xx responses as contract-aware failures, not free-form errors
* preserve `requestId` and `traceparent` in logs and downstream reports
* if provenance or freshness metadata is present, return it unchanged so trust is not lost in the handoff
