Monitor Tool

Category: General  ·  Sub-category: ai-tooling  ·  Last updated:
When the persona needs to watch a long-running local subprocess for completion or stream events from it without burning conversation turns on busy-waiting, reach for the Monitor tool. Monitor is event-driven (wakes the agent when the watched condition fires), strictly more token-efficient than a `/loop` poll, and the right primitive for 'wait until X happens' on local artifacts (file mtime, ps liveness, log-line match, port-open). Use when: waiting for a background-agent build to finish, watching a log file for an error pattern, blocking on a port becoming available, or any 'fire when condition holds' pattern against local state. Composes with `run-in-background-bash` (which detaches the work; Monitor watches it) and the dead-agent-detection memory rule (which obligates probe-the-artifact over poller-cadence inference).
