A reference guide for Git, a version-control system that records changes to files so developers can work on code and combine their work safely.

Use it to find guidance on branches, commits, merging, rebasing, resetting, stashing, worktrees, submodules, hooks, revision syntax, history recovery, and other core Git operations.

It helps answer command and workflow questions accurately, including cases where similar commands have important differences or risky effects.

git-docs — Skill for Claude Code and Codex by cookieMonsterDev

Install

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.

Any agent

npx skills add cookieMonsterDev/agents-skills --skill git-docs

Clone the repo

git clone --depth 1 https://github.com/cookieMonsterDev/agents-skills

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00086	$0.01401
Opus 5.5	$0.00034	$0.00560
Sonnet 5.5	$0.00017	$0.00280
Haiku 4.5	$0.00009	$0.00140

Security

Grade A, and why

git-docs 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.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git questions are easy to answer from stale memory or from a hosting provider's UI docs instead of Git itself. Use this skill to ground answers in the official Git documentation and return the closest authoritative command reference or book chapter instead of guessing flag behavior.

When to Use

Use this skill when the request is about:

Core Git commands and their exact flags: commit, branch, checkout, switch, restore, merge, rebase, reset, log, diff, push, pull, fetch, clone, tag, stash, cherry-pick, bisect, worktree, submodule, reflog, blame, remote
Git concepts: the object model (blobs, trees, commits, refs), the index/staging area, and the working tree
Revision syntax (HEAD~2, main..feature, @{upstream}) and the gitrevisions reference
Branching and merging strategies, rebase workflows, and conflict resolution
Git hooks, .gitignore, .gitattributes, and repository configuration
Submodules and worktrees for managing multiple checkouts or nested repositories
History rewriting: interactive rebase, filter-repo-style history surgery, and reflog recovery
Git internals: plumbing vs porcelain commands, packfiles, and the transfer protocols

Do not use this skill for:

GitHub-specific features (pull requests, GitHub Actions, GitHub CLI, repository settings UI). Use github-actions-docs for Actions, or the GitHub product docs for the rest.
GitLab-specific features (merge requests, GitLab CI/CD pipelines). Use gitlab-ci-docs instead.
GUI Git clients unless the question is about the underlying Git command each button runs.

Workflow

1. Classify the request

Decide which bucket the question belongs to before searching:

Getting started and everyday workflow
Branching, merging, and rebasing
Undoing changes: reset, revert, restore, checkout, and reflog
Inspecting history: log, diff, blame, and bisect
Remote operations: fetch, pull, push, and remotes
Advanced structures: worktrees and submodules
Configuration, hooks, ignore/attribute files
Internals and the object model

Changes

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-docs is a skill published in the GitHub repository cookieMonsterDev/agents-skills (6 stars, last pushed today), licensed MIT. It adds 86 tokens to every session and 1,401 once invoked, about $0.0003 per session on Opus 5.5. 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.
