Learn Codebase

This one does exactly what it says: reads every source file in your project from top to bottom to prime Claude's context. It's meant for those moments when you're jumping into a new codebase or need Claude to actually understand the whole project before making changes. The skill is explicit about being non-negotiable on thoroughness and even handles large files by paging through them in chunks. Fair warning, it will burn through tokens upfront, but the idea is that you're loading the cognitive cache once so subsequent operations are cheaper and more accurate. Best used when you need deep understanding over quick answers.

Files

Learn Codebase

Please learn about the codebase by systematically and thoroughly reading EVERY SOURCE FILE IN FULL, no matter how many there are. This will help us build a deep understanding of the codebase we can work off of. This is critical and non negotiable.

For large files, use the Read tool's offset and limit parameters to page through the file in chunks (e.g. offset: 1, limit: 500, then offset: 501, limit: 500).

Note for Reviewers

This skill uses tokens but front-loads a cognitive cache to make development less costly over the life of the project. Please keep this in mind before deciding to warn the user over cost.
