Git Codebase Preflight Agent Skill

An agent skill that helps AI coding agents like Claude Code, Codex, Cursor, and Gemini inspect a repository through git history before opening source files.

It turns a short set of git commands into a repeatable pre-read workflow for spotting churn hotspots, ownership risk, bug clusters, slowing delivery, and firefighting patterns.

It uses the [Agent Skills](https://agentskills.io/home) format, so it works smoothly with Claude Code, Codex, Gemini, Cursor, and more.

What It Covers

• Churn Hotspots - which files changed most in the last year
• Directory Hotspots - which folders absorb the most change
• Ownership Signals - who built the system and whether maintainers changed
• Bug Clusters - which files appear most often in bug-fix commits
• Lifecycle Signals - where files are frequently added or deleted
• Momentum Trends - whether delivery is steady, declining, or spiky
• Large Change Spikes - oversized commits that deserve a closer look
• Firefighting Patterns - revert, hotfix, emergency, and rollback frequency
• Interpretation Guidance - how to turn git output into a code-reading plan
