# Project Structure

See a whole TypeScript or Swift codebase on one page

## What this does

It is hard to reason about a codebase you can only read a file at a time. This produces one compressed map of a TypeScript or Swift project: the files, what each one exposes, the shapes of those things, and where the boundaries are. It is sized to fit in a model's context, so you or another agent can hold the whole project at once.

### Top 3 things it does for you

- Get a map of an unfamiliar repository
- Hunt for duplicated code across the project
- Plan a refactor with the whole layout in view

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 Project Structure

A single-file symbol map of a TypeScript or Swift repository, compressed to fit inside an LLM context window. It covers the files, the symbols they export, typed signatures, and plugin boundaries.

It is built for the kind of thinking that needs the whole project at once: hunting for duplication, planning a refactor, getting your bearings in an unfamiliar architecture, or handing a full-project map to another agent.

## Questions

### Is Project Structure safe to install?

AIR scanned this exact version of Project Structure and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit bce6015dbde0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/project-structure.

### How do I install Project Structure?

Open https://airmarket.ai/app/project-structure 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/steipete/agent-scripts/tree/bce6015dbde00c15cdfef6d1fff72b247831f97e/skills/project-structure. Install from that link, not the branch.
