git-clean-gone

Clean up local branches with deleted remote tracking and their worktrees. Detects gone branches, squash-merged PRs (via gh), and rebased branches (via git cherry).

The plugin is a portable Agent Plugin with one Agent Skill, so the same package works in Claude Code, Codex, Copilot CLI and opencode.

Installation

Claude Code (Copilot CLI is the same with copilot in place of claude):

claude plugin marketplace add smykla-skalski/sai
claude plugin install git-clean-gone@sai

Codex:

codex plugin marketplace add smykla-skalski/sai
codex plugin add git-clean-gone@sai

opencode, or any agent that reads Agent Skills, loads skills/git-clean-gone/ directly:

ln -s /path/to/sai/plugins/git-clean-gone/skills/git-clean-gone ~/.config/opencode/skills/git-clean-gone

Local checkout: claude --plugin-dir /path/to/sai/plugins/git-clean-gone/

Usage

The skill deletes branches and worktrees, so it never runs on its own: in Claude Code and Copilot CLI invoke /git-clean-gone, in Codex $git-clean-gone (implicit invocation is disabled). On agents other than Claude Code, any request that does not name the skill gets a --dry-run preview first and deletes only after you confirm the whole list. The real run fetches again, so anything it deletes beyond the preview is called out in the summary.

/git-clean-gone
/git-clean-gone --dry-run
/git-clean-gone --no-worktrees
