  • Runs Shell scripts from its folder; calls bash, git and go

What it does

Git Worktree is an agent skill from davekilleen/Dex. This skill manages Git worktrees for isolated parallel development. It handles creating, listing, switching, and cleaning up worktrees with a simple interactive interface, following KISS principles.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/worktree-manager.sh`).

It sits in Development, covering Git worktrees. It works with Git. The repository describes itself as: Your AI Chief of Staff — a personal operating system starter kit that adapts to your role. No coding required.

When your agent uses it

  • Tasks that involve Git worktrees

Example prompts

  • “/git-worktree”

Requirements

  • A Bash shell

Workflow steps

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

  1. Copies .env, .env.local, .env.test, etc. from main repo
  2. Ensures .worktrees is in .gitignore
  3. Creates consistent directory structure

What it can do on your machine

Read from SKILL.md and the folder at commit ab5d6ad. 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

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • bash
    • git
    • go

    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

Git Worktree loads about 2.2k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 616 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

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.

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 616 words (~2,156 tokens).

“This skill provides a unified interface for managing Git worktrees across your development workflow. Whether you're reviewing PRs in isolation or working on features in parallel, this skill handles all the complexity.”
