MCP Factory Coordination (2026-02-12 — 2026-02-13)
18. Parallel agents on shared filesystem = disaster
- Spawned 5-10 agents simultaneously writing to same directory. They deleted each other's files.
- Rule: SEQUENTIAL or SEPARATE directories, then merge. Never parallel writes to same folder.
19. "Delete everything and rebuild" agents are time bombs
- Agent deletes all files in minute 1, times out at minute 10 with 30% rebuilt. Server is now worse.
- Rule: NEVER tell agents to delete first. Build alongside existing, then swap.
20. Factory monitor cron + manual spawns = competing agents
- Cron spawning fix agents + manual spawning rebuild agents = 3-4 agents fighting over same server.
- Rule: Disable cron monitors before manually spawning agents for same targets.
22. Git checkout HEAD restores wiped files
git checkout HEAD -- servers/{name}/instantly restores committed files after rogue agent wipes.- Rule: Commit after each server completes. Commit early, commit often.
MCP Quality Standards (2026-02-13)
26. Start from actual API spec — never hand-pick tools from vibes
- Pull OpenAPI/Swagger spec. Build complete endpoint inventory BEFORE deciding tools.
27. Prioritize by user workflows, not alphabetical CRUD
- Tier 1 (daily, 10-15 tools) → Tier 2 (power user, 15-30) → Tier 3 (complete coverage).
28. Rich tool descriptions drive agent behavior
- BAD: "Lists contacts" → GOOD: "Lists contacts with filtering by email, name, tag, date range. Use when user wants to find/browse contacts. Paginated up to 100."
29. Coverage manifest for every server
- Track: total endpoints, implemented, intentionally skipped (with reasons), not yet covered. Target 80%+.
30. 7-8 tools = demo, not product
- Small API (<30 endpoints): 15-20 tools. Medium (30-100): 30-50. Large (100+): 50-80+.
31. Consistent naming across ALL servers
- list_, get_, create_, update_, delete_, search_. Domain verbs: send_email, cancel_event. All snake_case.
32. Pagination + rate limits in every server
- Cursor/page tokens, reasonable defaults (25-100), has_more indicators, 429 retry with backoff.
Computer Use Discovery (2026-02-15)
42. macOS TCC permissions via sudo sqlite3
sudo sqlite3 "/Library/Application Support/com.apple.TCC/TCC.db"— set auth_value=2 for kTCCServiceScreenCapture.
44. Brave requires restart for "Allow JavaScript from Apple Events"
45. screencapture -x -R x,y,w,h for cropped screenshots
Misc Historical
Python unbuffered output
- Use
python3 -ufor background scripts.
Veo download workaround
client.files.download()returns 404. Grab URI fromvideo.video.uri+?key=API_KEY.
iMessage group chat format
- Chat IDs:
chat358249523368699090. Send format:any;+;chat358249523368699090.
Sending images to iMessage group chats
- AppleScript unreliable for images. Use BlueBubbles API directly.
Edit tool requires EXACT text match
- Always read file first to get exact text before editing.
Compaction ≠ crash
- Compaction compresses context, doesn't stop responses. If I went silent, something else happened.
Sub-agent results arrive as system messages
- After compaction, check sessions_list for completed sub-agents.
Cloudflare Registrar is dashboard-only
- No API for new domain registration.
Wrangler OAuth vs API Token
- Different scopes. Check both.
