compose:merge

compose:merge is a skill for Claude Code, Codex from XiaomiMiMo/MiMo-Code. It costs 41 tokens per session (2,043 once invoked), scanned A, original, MIT.

A completion workflow for deciding how finished, tested changes should be integrated into a Git project.

In plain words
What is it for?
Finishing a development branch, verifying tests, detecting whether work uses a separate worktree, and choosing an integration path.
Why use it?
It checks that tests pass and considers the repository state before offering choices such as merging, opening a pull request, or cleaning up.

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:merge 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 7d 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.

Finishing a Development Branch

Overview

Guide completion of development work by presenting clear options and handling chosen workflow.

Core principle: Verify tests → Detect environment → Present options → Execute choice → Clean up.

Announce at start: "I'm using the compose:merge skill to complete this work."

The Process

Step 1: Verify Tests

Before presenting options, verify tests pass:

# Run project's test suite
npm test / cargo test / pytest / go test ./...

If tests fail:

Tests failing (<N> failures). Must fix before completing:

[Show failures]

Cannot proceed with merge/PR until tests pass.

Stop. Don't proceed to Step 2.

If tests pass: Continue to Step 2.

Step 2: Detect Environment

Determine workspace state before presenting options:

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)

This determines which menu to show and how cleanup works:

State Menu Cleanup
GIT_DIR == GIT_COMMON (normal repo) Standard 4 options No worktree to clean up
GIT_DIR != GIT_COMMON, named branch Standard 4 options Provenance-based (see Step 6)
GIT_DIR != GIT_COMMON, detached HEAD Reduced 3 options (no merge) No cleanup (externally managed)

Step 3: Determine Base Branch

# Try common base branches
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null

If the base branch is ambiguous, confirm through compose:ask:

  • header: Base Branch
  • question: This branch appears to have split from <detected>. Correct?
  • options:
    • label: Yes, <detected>, description: Use <detected> as merge target
    • label: Different branch, description: I'll specify the correct base branch

If no user is available, use the detected base branch and proceed.

Step 4: Present Options

Normal repo / named-branch worktree — use compose:ask:

  • header: Complete Work
  • question: Implementation complete. What would you like to do?
  • options:
    • label: Merge locally, description: Merge back to <base-branch>
    • label: Create PR, description: Push branch and open a Pull Request
    • label: Keep as-is, description: Leave the branch — I'll handle it later
    • label: Discard, description: Delete branch and all commits

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

compose:merge is a skill published in the GitHub repository XiaomiMiMo/MiMo-Code (13,030 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 2,043 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
