WHAT IT DOES

What agenda_log_entry does on VibeServe

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

WHY IT NEEDS A POLICY

Why agenda_log_entry needs a policy

This tool creates/appends a log entry associated with an agenda goal. It writes new data (a work entry record) to the system but does not delete anything or execute code. The blast radius is low since it only records work tracking information.

agenda_log_entry Rate-limited

agenda_log_entry 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.
