sumgit

A Claude Code skill that tells the story of your day's git commits using parallel AI agents.

What it does

/sumgit analyzes your repository's commits from today and generates a narrative summary by:

1. Gathering commits - Collects all commits since midnight
2. Identifying workstreams - Clusters commits into logical groups (features, fixes, refactoring, etc.)
3. Deploying parallel agents - Launches Explore agents to analyze each workstream
4. Synthesizing a narrative - Combines findings into a cohesive story with metrics and themes

Example Output

19 commits today! Deploying agents to analyze workstreams...

# The Complete Day: December 27, 2025

19 Commits Across 4 Major Workstreams

---

## Homepage & Marketing Polish
6 commits transforming the marketing site...
- Removed dead links, unified navigation
- Added Framer Motion entrance animations
- Refreshed copy to be more action-oriented

## Interview Reports & Transcripts
4 commits enhancing the core product...
- New transcript dialog viewer with chat-style UI
- PDF radar chart color coding improvements

...

## Day Summary

| Metric           | Value |
|------------------|-------|
| Total commits    | 19    |
| Files modified   | 40+   |
| New components   | 4     |

## Themes of the Day

1. **Simplification**: Remove dead links, merge components
2. **Clarity**: Action-oriented copy, intent-aware UX
3. **Robustness**: Auth race conditions fixed

Installation

Option 1: Clone to personal skills (recommended)

git clone https://github.com/lofimichael/sumgit ~/.claude/skills/sumgit

Option 2: Add to your project

# In your project root
git clone https://github.com/lofimichael/sumgit .claude/skills/sumgit

Then commit .claude/skills/sumgit/ to share with your team.

Usage

In any git repository with commits from today:

/sumgit

Requirements

• Claude Code CLI
• A git repository with commits

How it works

The skill instructs Claude to:

1. Run git log --since="midnight" to gather today's commits
2. Analyze commit messages and file paths to identify workstreams
3. Deploy up to 3 Explore agents in parallel (one per workstream)
4. Synthesize agent findings into a narrative summary

Agents run concurrently for speed, each analyzing specific files and changes in their assigned workstream.

Edge cases

• No commits today: Shows a friendly message with the last commit date
• 1-2 commits: Simple summary without agent deployment
• 20+ commits: Higher-level grouping to keep output digestible
