Coordinate multiple AI agents working on the same machine and codebases via the devtools-mcp local collaboration layer: file-touch reporting hooks, advisory file claims (leases), conflict checks, and the /collab dashboard page, all linked to tracker tasks. Use when running more than one agent at once (Claude Code, Cursor, Codex), when an edit warns that another agent is on the file, when asked "who is working on what", or to claim files before a big refactor. A multi-user team collab server is coming soon; this is its single-machine precursor.
