SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill produces a readable, progressive overview of unfamiliar code or a pull request's changes — what the code does, how it flows, and where to start — so you can get up to speed before working on or reviewing it. It writes the overview to a scratch file and does not modify code. It does not assess code quality or provide durable documentation.

Core Features & Use Cases

  • Read-only overview: explains purpose, flow, and entry points without editing the target.
  • Progressive disclosure: structures information to help newcomers understand quickly.
  • Handoff-ready: produces a concrete starting point for developers to begin exploration.

Quick Start

Invoke the code-overview skill on a target file, directory, symbol, or PR with a size hint to generate a readable, non-destructive overview.

What is the best way to understand a pull request's changes before reviewing it?

Understanding a pull request's changes before reviewing is best done with an AI-assisted code overview. It extracts the purpose, flow, and entry points of the PR changes progressively, providing a concrete starting point for your review.

Can I generate a code explanation for a specific symbol or directory?

Yes, you can generate a code explanation for a specific symbol or directory. The tool accepts file, directory, symbol, or PR references as targets to orient new readers and help them understand the code flow quickly.

Does a read-only code overview tool assess code quality or generate documentation?

A read-only code overview tool does not assess code quality or generate durable documentation. It strictly provides a progressive overview of what the code does and how it flows, avoiding any quality judgments or code alterations.

How do I orient myself when starting work on a new software engineering project?

To orient yourself when starting work on a new software engineering project, generate a progressive code overview. It highlights entry points and explains the code flow, creating a handoff-ready starting point for exploration.
