WHAT IT DOES

What record_test_result does on State Trace

AI agents use record_test_result to create or update resources in State Trace — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your State Trace environment.

WHY IT NEEDS A POLICY

Why record_test_result needs a policy

This tool creates/stores data (a test result record linking a command to its observation) in the working memory graph. It is a write operation with no indication of irreversibility, code execution, financial impact, or deletion. Misuse potential is low as it only logs test results.
