learn-codebase
- Use it when:
- You start on a new or unfamiliar project and want the agent to know all of it before working.
- It does:
- Has the agent read every source file in full, however many there are, paging through large files in chunks.
- You get:
- An agent that has read the whole codebase; it writes nothing.
- Costs:
- Many tokens and much of the context window, more the larger the codebase; the skill argues this up-front cost makes later work cheaper.
- Unlike smart-explore:
- That one, from the same plugin, fetches only the symbols a task needs; this one reads everything at once.
Reads every source file in full, however large the codebase, which can take many tokens and much of the context window.
TL;DR
The whole skill is one instruction: read every source file in full, which it calls critical and non-negotiable, using the Read tool's offset and limit to page through big files. It includes a note asking reviewers not to warn you about the cost, since front-loading the codebase is meant to make development cheaper over the project's life; on a large codebase the reading still takes many tokens and much of the context window. With claude-mem installed, each read also becomes a memory observation, and claude-mem's how-it-works skill suggests running it to load a whole repo into memory in one pass.

Test-first work, implementation from specs, git hygiene and scope control. Everything for building software: planning, coding, debugging, design, frameworks, cloud, agents and skills. |

| Type |
A one-shot action you invoke by name, such as turning the conversation into a PRD. |
| Effect |
Adds no side effects of its own. It shapes how the agent thinks, writes or reviews. Guidelines and routers are always effect:none, even when the task they support edits code. |
| Needs |
Instructions only. Works in any agent that supports skills. |

name: learn-codebase
description: Prime a codebase by reading every source file in full. Use when starting work on a new or unfamiliar project, or when the user asks to "learn the codebase", "read the codebase", "prime", or "get up to speed".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.
