git-commits

A set of rules for keeping Git commits under human control. Git is the tool used to track code changes and group them into saved revisions.

In plain words
What is it for?
Use it when an agent is inspecting changes, preparing a commit message, checking for secrets, or suggesting the Git commands a human should run.
Why use it?
It stops an AI agent from staging files or creating commits without a person reviewing the changes first.

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.

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

git-commits 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 2d 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.

Git Commit Practices (prest-mcp-adapter)

Commits are a human action. The AI must never run git commit, git add (to stage for a commit), or git commit --amend — even when the user says "commit this" or "commit your changes."

When commits are in scope, the AI may inspect the repo and prepare a commit for the human; the human runs the final git commands locally.

What the AI Must Never Do

  • Run git commit or git commit --amend
  • Run git add to stage files for a commit
  • Create commits to "save progress" or after finishing a task
  • Create empty commits
  • Push to the remote unless the user explicitly asks (see Push below)

If the user asks you to commit, decline the git command and instead offer a ready-to-run suggestion (message + git add / git commit commands they can copy).

What the AI May Do

  • Run read-only inspection: git status, git diff, git log
  • Draft a commit message and list which paths to stage
  • Warn about secrets (.env, credentials, tokens, keys) that must not be committed
  • Fix hook/lint issues in code when asked — the human commits after validation

Git Safety Protocol

When any git write command is in scope (e.g. push, branch ops), still follow:

  • Never update git config (git config, global or local)
  • Never run destructive or irreversible commands (push --force, reset --hard, etc.) unless the user explicitly requests them
  • Never skip hooks (--no-verify, --no-gpg-sign, etc.) unless the user explicitly requests it
  • Never force-push to main or master; warn the user if they ask
  • Never use interactive git (git add -i, git rebase -i)

Suggesting a Commit (human runs these)

1. Inspect (run in parallel)

git status
git diff
git log -10 --oneline

2. Draft the message

  • 1–2 sentences focused on why, not a file list
  • Prefer Conventional Commits (feat:, fix:, chore:, refactor:)
  • List only the paths the human should stage; never include secrets

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-commits is a cursor rule published in the GitHub repository prest/prest-mcp-adapter (0 stars, last pushed 1mo ago), licensed MIT. It adds 635 tokens to every session, about $0.0032 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 2026-08-31.
