main or master branch.Run the GC script in dry-run mode to list what would be cleaned without making any changes:
./scripts/harness/gc.sh --dry-run
If the script does not support --dry-run, manually inspect and list:
done or failed status beyond config.workspace.retentionDaysShow the user the full list before proceeding.
Present the dry-run output to the user and ask:
The following worktrees and branches will be removed. Confirm to proceed? (yes / no)
Do not proceed if the user does not confirm. If the user says no, stop and report that no changes were made.
After confirmation, run the GC script:
./scripts/harness/gc.sh
GC targets per docs/harness/ENTROPY.md:
| Target | Criteria | Action |
|---|---|---|
| Completed worktrees | PR merged, worktree still present | git worktree remove |
| Stale branches | Last commit > 30 days ago | git branch -d (local and remote) |
| Unreferenced utilities | No import references + > 30 days old | Flag only — do not delete, ask user |
After the script completes, report:
