Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.01399 |
| Opus 5.5 | $0.00029 | $0.00560 |
| Sonnet 5.5 | $0.00015 | $0.00280 |
| Haiku 4.5 | $0.00007 | $0.00140 |
Grade A, and why
git-commit 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 1mo 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.
This is a copy
89% identical to git-commit — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Commit
Create a single, well-crafted git commit from the current working tree changes.
Context
If you are not Claude Code, skip to the "Context fallback" section below and run the command there to gather context.
If you are Claude Code, the five labeled sections below (Git status, Working tree diff, Current branch, Recent commits, Remote default branch) contain pre-populated data. Use them directly throughout this skill -- do not re-run these commands.
Git status:
!git status
Working tree diff:
!git diff HEAD
Current branch:
!git branch --show-current
Recent commits:
!git log --oneline -10
Remote default branch:
!git rev-parse --abbrev-ref origin/HEAD 2>/dev/null || echo '__DEFAULT_BRANCH_UNRESOLVED__'
Context fallback
If you are Claude Code, skip this section — the data above is already available.
Run this single command to gather all context:
printf '=== STATUS ===\n'; git status; printf '\n=== DIFF ===\n'; git diff HEAD; printf '\n=== BRANCH ===\n'; git branch --show-current; printf '\n=== LOG ===\n'; git log --oneline -10; printf '\n=== DEFAULT_BRANCH ===\n'; git rev-parse --abbrev-ref origin/HEAD 2>/dev/null || echo '__DEFAULT_BRANCH_UNRESOLVED__'
Workflow
Step 1: Gather context
Use the context above (git status, working tree diff, current branch, recent commits, remote default branch). All data needed for this step is already available -- do not re-run those commands.
The remote default branch value returns something like origin/main. Strip the origin/ prefix to get the branch name. If it returned __DEFAULT_BRANCH_UNRESOLVED__ or a bare HEAD, try:
gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'
If both fail, fall back to main.
If the git status from the context above shows a clean working tree (no staged, modified, or untracked files), report that there is nothing to commit and stop.
If the current branch from the context above is empty, the repository is in detached HEAD state. Explain that a branch is required before committing if the user wants this work attached to a branch. Ask whether to create a feature branch now. Use the platform's blocking question tool (AskUserQuestion in Claude Code, request_user_input in Codex, ask_user in Gemini). If no question tool is available, present the options and wait for the user's reply before proceeding.
What this file has done since we first saw it
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.

git-commit is a skill published in the GitHub repository Jerrylalala/compound-engineering (6 stars, last pushed 4mo ago), licensed MIT. It adds 73 tokens to every session and 1,399 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 89% identical to git-commit, differing in 12 lines, and is treated as a copy.
