What problem does it solve? Coordinating multiple agents against a shared GitHub Project board causes race conditions, stale IDs, and duplicated writes. This Skill centralizes all gh project and gh issue operations behind a single subagent that caches board IDs, serializes writes with a lock file, and returns structured JSON results. ## Core Features & Use Cases - Board Reads: List column items, open PRs, tracked issue markers, and fetch the next available task with parallel-safe operations. - Serialized Writes: Create issues, post plan comments, set column status, and apply labels under a flock-style lock to prevent concurrent write conflicts. - ID Caching & Recovery: Cache project, status field, and option IDs in .workflow/temp/ and regenerate them automatically on 422 errors or via refresh-cache. - Use Case: A coordinator agent needs the next READY task while a coder agent marks its issue IN-PROGRESS; both delegate to board-man, which serves the read immediately and serializes the status write safely. ## Quick Start Ask the board-man subagent to run the operation "next-task <repo>" and use the returned JSON issue details to begin work.
