WHAT IT DOES

What share_trace_anon does on Maple

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

WHY IT NEEDS A POLICY

Why share_trace_anon needs a policy

This tool uploads/sends data (an anonymized trace) to an external community pool, which is a Write operation — it creates or posts data to an external repository. While data is anonymized, misuse could still result in leaking session traces or behavioral data to a shared external pool, warranting medium severity. It does not execute code, destroy data, or involve finances.

From the tool's definition Share an anonymized trace to the community pool to improve evolved-skill recommendations.
