387 "Monitor GitHub PRs in {repo}{filters_note} and report only changes.\n\n\
388 ## Workflow\n\n\
389 ### 1. Fetch Current State\n\
390 ```bash\n\
391 gh pr list -R {repo} {filters} --json number,title,state,statusCheckRollup,reviewDecision,labels,updatedAt --limit 100\n\
392 ```\n\n\
393 Parse as JSON array of PRs. Each PR needs: number, title, state (OPEN/DRAFT/MERGED/CLOSED), \
394 statusCheckRollup (PENDING/FAILURE/SUCCESS/NEUTRAL), reviewDecision (APPROVE/REQUEST_CHANGES/REVIEW_REQUIRED/COMMENTED), \
395 labels (array), updatedAt (timestamp).\n\n\
396 ### 2. Retrieve Previous State\n\
397 Use mcp context_get key: \"loop_monitor_state_{repo_slug}\".\n\n\
398 If nothing found, store current state and report:\n\
399 \"✓ Initial snapshot of {repo}. {count} PRs. Monitoring now.\"\n\
400 Then exit.\n\n\
401 ### 3. Diff: Identify Only Meaningful Changes\n\n\
402 **New PRs** (in current, not in previous):\n\
403 - Report: \"🆕 #{number}: {title} ({state})\"\n\n\
404 **Status Transitions** (state changed):\n\
405 - DRAFT → OPEN: \"🔓 #{number}: opened\"\n\
406 - OPEN → MERGED: \"✅ #{number}: merged\"\n\
407 - OPEN → CLOSED: \"❌ #{number}: closed\"\n\n\
408 **Review Status Changes** (reviewDecision changed):\n\
409 - → REQUEST_CHANGES: \"🚫 #{number}: changes requested\"\n\
410 - → APPROVE: \"✅ #{number}: approved\"\n\n\
411 **Status Checks Changed** (statusCheckRollup changed):\n\
412 - → FAILURE: \"⚠️ #{number}: checks failing\"\n\
413 - FAILURE → SUCCESS: \"✅ #{number}: checks passing\"\n\
414 - PENDING → SUCCESS: \"✅ #{number}: checks complete\"\n\n\
415 **Label Changes** (labels added/removed):\n\
416 - If `pool:ready` added: \"🏷️ #{number}: marked pool:ready\"\n\
417 - If `pool:ready` removed: \"🏷️ #{number}: unmarked pool:ready\"\n\n\
418 Skip cosmetic changes (comment count, updatedAt alone).\n\n\
419 ### 4. Format Output\n\n\
420 If changes found:\n\
421 ```\n\
422 ## PR Monitor: {repo}\n\n\
423 {list of changes, one per line, reverse-chronological}\n\n\
424 Summary: {count} new, {count} status changes, {count} review updates, {count} check failures\n\
425 Last check: {timestamp}\n\
426 ```\n\n\
427 If no changes:\n\
428 ```\n\
429 ✓ No changes to {repo}.\n\
430 ```\n\n\
431 ### 5. Store New State\n\
432 Use mcp context_set key: \"loop_monitor_state_{repo_slug}\" with compact JSON:\n\
433 ```json\n\
434 {{\n\
435 \"timestamp\": \"2025-03-10T14:35:00Z\",\n\
436 \"prs\": [\n\
437 {{ \"number\": 68, \"title\": \"docs: add task sizing\", \"state\": \"OPEN\", \"statusCheckRollup\": \"SUCCESS\", \"reviewDecision\": null, \"labels\": [\"docs\"] }}\n\
438 ]\n\
439 }}\n\
440 ```\n\n\
441 ## Error Handling\n\n\
442 If `gh pr list` fails:\n\
443 - Report: \"❌ Failed to fetch PRs: {error}\"\n\
444 - Don't update context\n\n\
445 ## Usage\n\n\
