WHAT IT DOES

What update_phase does on RoadBoard

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

WHY IT NEEDS A POLICY

Why update_phase needs a policy

This tool modifies project state (phase metadata) in a reversible manner. It does not delete data (thus not Destructive), does not execute arbitrary code (thus not Execute), does not move money (thus not Financial), and does not merely retrieve data (thus not Read).

From the tool's definition Tool name 'update_phase' and description 'Update fields of an existing phase' indicates modification of existing data. The description specifies reversible changes: title, status, dates, linked decision—none of which are deletion or destruction operations.

Verdict

update_phase Rate-limited

update_phase 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.
