Prune

Branch Cleanup

Delete merged and stale local branches safely, with preview and confirmation.

Arguments

• $ARGUMENTS - Optional: --stale-days <N> to override the 30-day stale threshold, --remote to also delete remote branches

Context

• Current branch: !git branch --show-current
• Remote: !git remote 2>/dev/null | head -5

Instructions

Resolve the script path — use the first that exists:

1. ~/.claude/skills/prune/scripts/prune.sh (deployed via symlink)
2. agents/skills/prune/scripts/prune.sh (repo-relative, for development/workspaces)

Step 1: Preview branches

Run the preview command, forwarding any --stale-days argument:

bash <script-path> preview [--stale-days N]

Handle the exit code:

• Exit 0 — Present the output as a formatted table (see format below). Proceed to Step 2.
• Exit 3 — Tell the user: "All branches are current — nothing to prune." and stop.
• Exit 1 — Report the error from stderr.

Format the preview output as:

## Branch Cleanup Preview

### Merged (safe to delete)
| Branch | Last Commit | Merged Into |
|--------|------------|-------------|
| <branch> | <date> | <default> |

### Stale (no commits in N days)
| Branch | Last Commit |
|--------|------------|
| <branch> | <date> |

### Skipped
| Branch | Reason |
|--------|--------|
| <branch> | <reason> |

Step 2: Confirm and delete

Ask the user which branches to delete. Accept "all", specific branch names, or "none".

For confirmed branches, run the delete command:

bash <script-path> delete [--remote] <branch1> [branch2 ...]

Include --remote only if the user passed it in $ARGUMENTS.

Handle the exit code:

• Exit 0 — Show the output block verbatim as your final response.
• Exit 1 — Report the error from stderr.
