Smart Commit

AI-powered git commit message generation using LLM. Creates meaningful commit messages from code changes.

Capabilities

1. Amend Last Commit – Summarize staged/unstaged changes and amend the last commit message
2. Squash Commits – Summarize last N commits and create a consolidated commit
3. Interactive Commit – Confirm files with user, then summarize and create new commit

Quick Start

For New Commit

# Show changed files and ask user confirmation
git status

# After confirmation, summarize changes with LLM
# Create commit with generated message

For Amending

# Get diff of changes to amend
git diff --cached  # staged
git diff HEAD~1    # compared to last commit

# LLM summarizes, then
git commit --amend -m "new message"

For Squashing

# Get last N commit messages and diffs
git log -n N --format="%H %s"

# LLM summarizes, then
git reset --soft HEAD~N
git commit -m "consolidated message"

Workflow Decision Tree

User wants git commit help?
├─ "amend" or "修改"? → Amend workflow
├─ "squash" or "合并" + number? → Squash workflow
└─ New commit? → Interactive workflow

Amend Workflow

1. Get changes: git diff --cached (staged) or git diff HEAD~1 (all changes since last commit)
2. Send to LLM with prompt from references/prompts.md section “Amend Commit”
3. User reviews suggested message
4. git commit --amend -m "message"

Squash Workflow

1. Get last N commits: git log -n N --format="%H|%s|%an|%ad"
2. Get combined diff: git diff HEAD~N..HEAD
3. Send to LLM with prompt from references/prompts.md section “Squash Commits”
4. User reviews suggested message
5. git reset --soft HEAD~N && git commit -m "message"

Interactive Commit Workflow

1. Show git status to user
2. Ask user to confirm which files to include
3. Get diff for confirmed files
4. Send to LLM with prompt from references/prompts.md section “New Commit”
5. User reviews suggested message
6. git add <files> && git commit -m "message"
