# Codebase Scanner

Keep your project's docs honest as the code moves under them

## What this does

Project docs go stale the moment the code changes, and nobody notices until an agent acts on the wrong picture. This reads the codebase and writes the project documentation for you, doing a full pass the first time and only looking at what changed after that. Reach for it when starting a repo agents will work in, or when you suspect the docs no longer match reality.

### Top 3 things it does for you

- Bootstrap docs for a repo that agents will work in
- Refresh project documentation after the architecture changed
- Check whether the docs have drifted from the code

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Codebase Scanner

This reads a codebase and produces project-doc.md and AGENTS.md from what it finds. The first run is a full scan; later runs are a smart delta scan that looks for what has changed.

It fits three moments: bootstrapping a new agent-driven repo, refreshing documentation after the architecture has shifted, and running a delta scan specifically to catch drift.

It uses understand-anything and context-mode when those are available and falls back to native tools when they are not. AGENTS.md is only updated when architectural changes are detected, and only with human confirmation.

## Questions

### Is Codebase Scanner safe to install?

AIR scanned this exact version of Codebase Scanner and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit be57c0b2e3c0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/scan.

### How do I install Codebase Scanner?

Open https://airmarket.ai/app/scan on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/wshobson/agents/tree/be57c0b2e3c05c528ca6132b87410b385718775f/plugins/ship-mate/skills/scan. Install from that link, not the branch.
