What it does

Clean Gone Branches is an agent skill from fcakyon/claude-codex-settings. This skill should be used when user asks to "clean gone branches", "remove deleted local branches", "prune branches removed from remote", or explicitly invokes "clean-gone-branches".

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Git worktrees. The repository describes itself as: Battle-tested Claude Code, OpenAI Codex, Cursor configs, plugins, hooks and agents with Kimi, MiniMax and GLM API support. The licence is Apache-2.0.

When your agent uses it

  • Asks to clean gone branches
  • Remove deleted local branches
  • Prune branches removed from remote
  • Explicitly invokes clean-gone-branches

Example prompts

  • “clean gone branches”
  • “remove deleted local branches”
  • “prune branches removed from remote”
  • “/clean-gone-branches”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Update remote references
  2. Inspect local state
  3. Remove worktrees first
  4. Delete the gone branches
  5. Report the result

What it can do on your machine

Read from SKILL.md and the folder at commit 7a519d8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Clean Gone Branches loads about 237 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~237

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
This skill should be used when user asks to "clean gone branches", "remove deleted local branches", "prune branches removed from remote", or explicitly invokes "clean-gone-branches".

Clean Gone Branches

Remove local git branches that have been deleted from the remote.

Process

  1. Update remote references

    • Run git fetch --prune.

  2. Inspect local state

    • Run git branch -vv to find branches marked as [gone].
    • Run git worktree list to see whether any of those branches still have worktrees.

  3. Remove worktrees first

    • For each [gone] branch that still has a worktree, remove the worktree before deleting the branch.

  4. Delete the gone branches

    • Delete each local branch marked as [gone].

  5. Report the result

    • List removed worktrees and deleted branches.
    • If there are no [gone] branches, report that nothing needed cleanup.
