compose:worktree

compose:worktree is a skill for Claude Code, Codex from XiaomiMiMo/MiMo-Code. It costs 35 tokens per session (2,162 once invoked), scanned A, original, MIT.

A workflow skill for creating an isolated Git worktree before starting implementation work.

In plain words
What is it for?
Use it when beginning feature work or following an implementation plan that needs its own branch and working directory.
Why use it?
It keeps feature changes separate from the current workspace and reduces the risk of mixing unrelated edits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

compose:worktree scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Using Git Worktrees

Overview

Ensure work happens in an isolated workspace. Prefer your platform's native worktree tools. Fall back to manual git worktrees only when no native tool is available.

Core principle: Detect existing isolation first. Then use native tools. Then fall back to git. Never fight the harness.

Announce at start: "I'm using the compose:worktree skill to set up an isolated workspace."

Step 0: Detect Existing Isolation

Before creating anything, check if you are already in an isolated workspace.

GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
BRANCH=$(git branch --show-current)

Submodule guard: GIT_DIR != GIT_COMMON is also true inside git submodules. Before concluding "already in a worktree," verify you are not in a submodule:

# If this returns a path, you're in a submodule, not a worktree — treat as normal repo
git rev-parse --show-superproject-working-tree 2>/dev/null

If GIT_DIR != GIT_COMMON (and not a submodule): You are already in a linked worktree. Skip to Step 3 (Project Setup). Do NOT create another worktree.

Report with branch state:

  • On a branch: "Already in isolated workspace at <path> on branch <name>."
  • Detached HEAD: "Already in isolated workspace at <path> (detached HEAD, externally managed). Branch creation needed at finish time."

If GIT_DIR == GIT_COMMON (or in a submodule): You are in a normal repo checkout.

  1. Check memory for a worktree-consent preference in the compose-preferences memory file, or check your instructions for a declared worktree preference. If either exists, honor it silently.

  2. If no saved preference, use compose:ask:

    • header: Worktree
    • question: Set up an isolated worktree? It protects your current branch from changes.
    • options:
      • label: Yes (Recommended), description: Create an isolated worktree for this work
      • label: No, description: Work directly on the current branch
      • label: Always use worktrees, description: Use worktrees now and remember for future sessions
      • label: Never use worktrees, description: Work in place now and remember for future sessions
