Our review

Examines repository structure and documentation to provide a quick overview of a codebase's architecture and purpose.

Strengths

  • Fast onboarding to new projects
  • Leverages existing docs (README, ai_docs)
  • Provides a clear, structured summary

Limitations

  • Relies on quality of documentation
  • Misses undocumented code details
  • May be insufficient for large monorepos
When to use it

When starting work on a new project or returning to a project after a break.

When not to use it

When you need deep code-level understanding beyond documentation.

Prime

Quickly understand and load a codebase context. This skill examines the repository structure, documentation, and AI docs to give you a comprehensive overview of how the project is organized and what it does.

Prerequisites

  • You're in a git repository or project directory
  • The project has a README.md file
  • Optionally, the project has an ai_docs/ directory with additional documentation

Workflow

  1. List repository files - Get an overview of what's tracked in the repository
  2. Read main README - Understand the project's purpose and structure
  3. Read AI documentation - Load any additional AI-focused documentation if it exists
  4. Summarize understanding - Provide a concise summary of the codebase

Instructions

Execute these sections in order to understand the codebase:

  1. Run git ls-files to see what's tracked
  2. Read and analyze @README.md to understand project purpose
  3. If available, read and analyze @ai_docs/README.md for technical architecture
  4. Summarize your findings in a clear, structured format

Examples

Example 1: Priming a Node.js project

User: Prime this codebase for me
Claude: [Lists files with git ls-files]
[Reads README.md]
[Reads ai_docs/README.md if exists]
Summary: This is a Node.js web application with...

Example 2: Getting quick context

User: I'm back on this project, what was it about?
Claude: [Executes prime workflow]
