park-workspace

Idle Claude sessions cost ~150-350 MB each. With 40+ open workspaces that is several GB doing nothing — but closing them loses the TODO value of an open workspace, and cmux's own agent hibernation has lost live sessions and worktrees before.

Parking is the middle path: the workspace stays open, only its processes go.

park.py is stdlib-only Python 3.9+ and needs the cmux CLI on PATH. The commands below assume park itself is on PATH — link it once:

ln -sf ~/.claude/skills/park-workspace/park.py ~/.local/bin/park

Without that link, call it as ~/.claude/skills/park-workspace/park.py <cmd>.
