## Description

MUST USE for ANY git operations: atomic commits, rebase/squash/fixup, and history search (blame, bisect, log -S, reflog). Load it before running git yourself, or pass load_skills=['git-master'] to the task that commits. Triggers: 'commit', 'rebase', 'squash', 'who wrote', 'when was X added', 'find the commit that'.

# Git Master

Use this skill when the user asks you to operate on Git history or answer a Git-history question. Be exact, conservative, and evidence-led. Read the repository state before you infer anything.

## Mode Gate

Classify the request first:

- `COMMIT`: stage and commit local changes.
- `REBASE`: rebase, squash, fixup, autosquash, reorder, split, or otherwise rewrite branch history.
- `HISTORY`: answer when, where, who, why, or which commit changed something.
- `STATUS`: inspect branch, diff, or working-tree state without changing it.

Do not commit, rebase, push, force-push, reset, stash-pop, or delete anything unless the user explicitly asked for that operation. If the request is only investigative, report findings and stop.

## Ground Truth

Gather independent facts in parallel when the tools allow it:

```bash
git status --short
git diff --stat
git diff --staged --stat
git branch --show-current
git log -30 --oneline
git log -30 --pretty=format:%s
git rev-parse --abbrev-ref @{upstream}
git merge-base HEAD origin/main
git merge-base HEAD origin/master
```

Missing upstream or missing `main`/`master` is normal. Fall back to the best available branch or report the missing fact. Never treat a failed lookup as proof.

## PR Body Evidence Attachments

When a PR body needs screenshots or terminal PNGs, use the repo reference at `docs/reference/github-attachment-upload.md`. The allowed hosting path is GitHub user attachments from the authenticated web attachment flow; never commit temporary images, never use GitHub Releases for PR evidence, and never use external image hosts. Do not log browser cookies, CSRF tokens, S3 form fields, or upload headers.

## Commit Mode

Commit only the user's requested changes. Preserve unrelated dirty work.
