Claude Code Monitor Tool: Live Event Streaming Replaces Sleep-Loop Polling for Background Processes
Claude Code v2.1.98 introduced the Monitor tool — a built-in watcher that streams background events directly into the conversation. Each event lands as a new transcript message that Claude reacts to immediately, enabling tail-a-training-run, watch-CI, or auto-fix-dev-server workflows without Bash sleep loops. Combined with /loop self-pacing (omit the interval and Claude schedules the next tick based on the task), this shifts Claude Code from request-response to event-driven agent behavior. Plugins can declare monitors via a top-level manifest key that auto-arms at session start.
