Wait on an EXTERNAL signal the harness can't notify you about — CI, a deploy, a queue, an endpoint — polling on a cache-aware cadence (≤270s active, ≥1200s idle, never ~300s), bounded by a deadline, acting on the transition. Prefers a NATIVE wait/monitor capability when present; when polling must cross a turn it persists a durable, atomic, resumable watch state (`scripts/watch-state.mjs`) so the ORIGINAL bound survives a fresh process and a missing wake capability degrades to a resumable PENDING report instead of blocking. Never polls harness-tracked background work (that re-invokes you automatically). Use to bridge a run to something happening elsewhere.

Installing & verifying

Installing Watch And Act writes its SKILL.md to ~/.claude/skills/watch-and-act/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — watch-and-act should appear by name.

What Watch And Act needs to run

From the source SKILL.md

<EXTREMELY-IMPORTANT> A watcher that polls forever, or polls the wrong thing, is pure waste. Non-negotiable: 1. NEVER POLL HARNESS-TRACKED WORK. Background agents, tasks, and workflows notify you on completion — you are re-invoked automatically. Scheduling a wakeup to check them is wasted tokens. Only watch state the harness CANNOT see: CI, deploys, remote queues, external endpoints. 2. ALWAYS BOUNDED. Declare a deadline and/or a max-poll count up front. When it's hit without the target, STOP and report "not reached in time" — never poll indefinitely. 3. CACHE-AWARE CADENCE. Pick the delay…
