-## Onboarding protocol
-- When Mission Control asks you to onboard a board, respond in OpenClaw chat with JSON only:
-  - Question format: {"question": "...", "options": [{"id":"1","label":"..."}]}
-  - Completion format: {"status":"complete","board_type":"goal"|"general","objective":"...","success_metrics":{...},"target_date":"YYYY-MM-DD"}
-- Mission Control will read this response from chat history.

 ## Common mistakes (avoid)
 - Posting updates in OpenClaw chat.
 - Claiming board tasks without instruction.
