Git Master

A disciplined Git operator for atomic commits, safe rebases, and evidence-backed history investigation.

What it does

  • Classifies every request into one of four modes — COMMIT, REBASE, HISTORY, STATUS — and refuses to write history unless you explicitly asked for it.
  • Commit mode: detects the repo's existing message style, reads the full diff (not just filenames), and splits work into atomic commits grouped by behavior, module, and revertability, verifying git diff --staged --stat before each commit.
  • Rebase mode: blocks rewriting main/master/dev/protected branches, mandates --force-with-lease over plain --force, resolves conflicts by intent, and always knows the recovery path (rebase --abort, reflog).
  • History mode: picks the right forensic tool (log -S, log -G, blame -L, log --follow, show, bisect, reflog) and cites hash, subject, path, and diff context as evidence.

Who it's for

  • Developers who want a clean, reviewable commit log instead of one giant catch-all commit.
  • Anyone nervous about rebase, squash, or force-push and wanting guardrails.
  • Reviewers and maintainers who regularly answer "who changed this line and when?"

Examples

  1. "Commit my current changes" → reads the whole diff, groups feature code + its tests into one commit and unrelated config/docs into separate ones, then reports hashes and leftover dirty files.
  2. "When did this error message change?" → runs git log -S "message text", confirms with git show, and answers with the commit hash, author, and diff snippet.
  3. "Squash my last few WIP commits" → uses git commit --fixup=<hash> plus GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash <base>, asking first if the branch was already pushed.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the packages/shared-skills/skills/git-master folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/code-yeongyu-git-master/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent && mkdir -p ~/.claude/skills && cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/git-master ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository into a temp folder: git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/git-master ~/.claude/skills/
  5. Verify with ls ~/.claude/skills/git-master — you should see SKILL.md.
  6. Restart Claude Code, then try a prompt like "commit my changes as atomic commits" to trigger the skill.
  7. (Optional) The PR-evidence section expects docs/reference/github-attachment-upload.md inside your working repo; skip that feature if the file isn't there.
