git-commit-from-diff

Create git commits by inspecting the current diff and staged changes, then crafting a concise commit message from the diff. Use when the user asks to commit changes, asks for a commit message based on the diff, or wants a commit workflow that stages files and commits in a single pass.

Git Commit From Diff

Overview

Create a git commit by staging changes (optionally all), inspecting the staged diff, and generating a concise commit message based on what changed.

Workflow

Check status with git status -sb.
If there are unrelated changes, ask whether to commit everything or only specific paths.
Stage changes with git add -A for “all changes” or git add <paths> for a scoped commit.
Inspect the staged diff to craft a message:
- Preferred: git diff --cached --stat for scope summary.
- If the message is unclear, skim git diff --cached for key themes.
Propose a concise, imperative commit message based on the diff. Use short subject lines like:
- Refine globe layout and sidebar rendering
- Update ingestion flow and cache handling
Commit with git commit -m "<message>".

Guardrails

Do not amend unless explicitly requested.
If there is nothing staged, stop and ask whether to stage changes.
If the user asks for a message “based on the diff,” always inspect the staged diff before committing.
