RISK

Why update_track_index is rated Medium

This tool modifies existing track metadata (summary, status, linked resources) in a reversible manner. It does not delete data (so not Destructive), execute arbitrary code (so not Execute), or involve financial transactions (so not Financial). It is a Write operation that updates structured documentation.

From the tool's definition Tool description explicitly states "Overwrite index.md for an existing conductor track" and "Use to update the track summary, status, or linked resources." The verb 'overwrite' indicates modification of existing data.

RECOMMENDED RULE

The rule that runs update_track_index safely

update_track_index Rate-limited

update_track_index 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.
