What it does

Featree is an agent skill from openwpm/OpenWPM. Use to create a feat/<slug bookmark AND spin up a new git worktree under <repo-root/.worktrees/<slug, then initialize crosslink hooks and an agent identity in the worktree so a child agent can work there. Trigger when the user says "make a worktree for <feature", "/featree …", or asks to spin up an isolated workspace for a feature.

Its SKILL.md is about 850 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. It works with Git. The repository describes itself as: A web privacy measurement framework.

When your agent uses it

  • Create a feat/<slug bookmark AND spin up a new git worktree under <repo-root/.worktrees/<slug
  • Then initialize crosslink hooks and an agent identity in the worktree so a child agent can work there
  • The user says make a worktree for <feature
  • Asks to spin up an isolated workspace for a feature

Example prompts

  • “make a worktree for <feature”
  • “/featree …”
  • “/featree”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Create the feature bookmark
  2. Generate worktree path
  3. Create the git worktree
  4. Initialize crosslink in the worktree
  5. Report to user

What it can do on your machine

Read from SKILL.md and the folder at commit da628ba. 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

Featree loads about 846 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 335 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~846

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 335 words (~846 tokens).

“The user provides a human-readable feature description (e.g. "add batch retry logic"). First create a feature bookmark using the feature skill, then move it into a new git worktree.”
