Git Commit Summarizer

This skill analyzes git commit history for specified users and generates detailed markdown summary reports. It helps track developer contributions, code changes, and project progress over time.

Capabilities

• User-Specific Analysis: Summarize commits for one or multiple git users
• Time-Based Filtering: Analyze commits from today or over specified number of days
• Report Generation: Create detailed markdown reports with commit statistics
• File Organization: Automatically save reports to .claude/git_commit_report/ directory
• Multi-User Support: Process multiple users in a single execution

Input Requirements

The skill requires:

• Usernames: One or more git usernames (comma-separated)
• Days: Optional number of days to analyze (defaults to today)

Example Input Format:

@git-commit-summarizer
Usernames: john.doe,jane.smith,alex.wong
Days: 7

Output Formats

Report Files: Markdown files saved to [current_repository]/.claude/git_commit_report/

• Filename format: [username]-[date].md
• Each report includes:
  • User information and analysis period
  • Total commit count
  • Commit details (hash, date, message, files changed)
  • Statistics (commits per day, files per commit)
  • Summary of changes

Console Output: Summary of processing results and report locations

How to Use

"Summarize git commits for user 'john.doe' over the last 3 days" "Generate commit reports for 'alice,bob,charlie' for today" "Analyze all commits by 'dev-team' in the last 14 days"

Scripts

• git_commit_analyzer.py: Main module for analyzing git commits and generating reports
• report_generator.py: Creates formatted markdown reports from commit data

Best Practices

1. Repository Context: Run this skill within a git repository directory
2. User Names: Use exact git usernames as they appear in commit history
3. Time Range: Specify days when you need historical analysis (default is today)
4. Report Location: Reports are saved in .claude/git_commit_report/ for easy access
5. Multiple Users: Use comma-separated format for analyzing multiple users at once

Limitations

• Requires git repository with commit history
• Only analyzes commits from the current repository
• Usernames must match exactly as in git commit history
• Time-based filtering uses relative days from current date
• Cannot analyze commits from remote repositories without local clone
