WHAT IT DOES

What rate_pattern_outcome does on Session Buddy

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

WHY IT NEEDS A POLICY

Why rate_pattern_outcome needs a policy

Rating a pattern outcome involves writing/updating data (a rating or score) associated with a previously applied pattern. This is a reversible modification to stored session/pattern metadata. No code execution, deletion, or financial implications are evident. Confidence is slightly reduced because the description is brief and doesn't detail exactly what data is modified.

rate_pattern_outcome Rate-limited

rate_pattern_outcome stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
