RISK

Why jobs_cancel is rated Critical

The description is empty, so confidence is reduced, but the name strongly implies a destructive/irreversible operation rather than a simple write.

From the tool's definition Tool name: 'jobs_cancel' — the word 'cancel' implies an irreversible or difficult-to-reverse state change on a job record.
