Audit trails for external tool calls
4 Jul 2026 · 6 min read
External tool calls need durable evidence: who asked, what ran, what changed, and why it was allowed.
When agents touch external systems, audit trails become the difference between operational confidence and guesswork.
AstraRunner treats this as an execution-platform concern: the run needs durable state, traceable decisions, cost visibility, and enough structure for teams to review what happened after the agent finishes.
Patterns that work
- Record requester, runner identity, tool, arguments, and result.
- Link approvals and policy checks to the tool span.
- Capture external resource IDs.
- Keep redacted summaries for sensitive outputs.
Implementation checklist
- Define audit schema.
- Make audit writes part of the transaction boundary.
- Support export for compliance review.
- Retain evidence by risk class.
Watch outs
- Raw tool output may contain secrets.
- Audit logs without policy decisions lack context.
- External IDs are needed for incident response.
