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 tool's and parameters to page through the file in chunks (e.g. , then ). 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. ---
