learn-codebase is an agent skill that primes context by reading every source file in a project in full, paging large files with offset and limit chunks.
About
learn-codebase is an agent skill that front-loads deep project familiarity by systematically reading every source file in full before coding starts. It triggers when users ask to learn the codebase, read the codebase, prime, or get up to speed on a new project. The workflow is explicit and non-negotiable: read each source file completely, using Read tool offset and limit parameters to page through large files in chunks such as 500-line windows. The skill frames this as building a cognitive cache that reduces costly rediscovery later, and asks reviewers to weigh token cost against long-project savings before warning users. Developers reach for it at the start of unfamiliar repositories, after large refactors, or whenever downstream tasks depend on accurate mental models of file layout, conventions, and cross-module dependencies. It does not substitute targeted debugging or incremental exploration when only one subsystem matters, but it excels when broad codebase literacy is the bottleneck before feature design or multi-file changes.
- Requires reading every source file in full before proceeding with implementation work.
- Pages large files with Read offset and limit chunks such as 500-line windows.
- Triggers on learn the codebase, prime, or get up to speed requests for new projects.
- Frames upfront reading as a cognitive cache that lowers later development cost.
- Asks reviewers to consider long-project savings before warning about token usage.

How do I build deep familiarity with an unfamiliar codebase before making multi-file changes or design decisions?
Prime agent context by reading every source file in a new or unfamiliar codebase before implementation work begins.
Who is it for?
Developers or agents starting on a new repository who need exhaustive upfront context before implementation.
Skip if: Skip when you only need a single file or subsystem and full-repo reading would waste tokens without benefit.
When should I use this skill?
User asks to learn the codebase, read every source file, prime context, or get up to speed on a new project.
What you get
Complete source-file coverage that gives the agent a working mental model of project structure, conventions, and dependencies.
- Complete source-file context
- Chunked reads of large files
By the numbers
- Pages large files in 500-line Read tool chunks
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.

FAQ
Must every source file be read completely?
Yes. The skill treats full-file reading as critical and non-negotiable before proceeding with implementation work.
How should large files be handled?
Page through them with Read offset and limit parameters, for example 500-line chunks until the entire file is covered.
