Tools

• audit_tools ~445 tokens

Each change is labeled breaking (removed tool or param, new required param, type or enum removal), suspicious (new text with injection

  Free: cancel a watch (no further checks or webhooks; not refunded). Needs watch_id and the secret returned when it was created.

  Free: state (active, expired, cancelled), interval, expiry, next check, last result (pin, grade, score, tool count) and webhook delivery counters for a watch. Needs watch_id and the secret returned when it was created.
