# CLAUDE.md / AGENTS.md Editor

> Configure how your agent behaves in this project with the built-in instructions editor.

The **CLAUDE.md** file (and its Codex equivalent **AGENTS.md**) is a special configuration file that tells your agent how to behave in this project. Coddo includes a built-in editor so you can manage it without leaving the app.

## What is CLAUDE.md / AGENTS.md?

`CLAUDE.md` is a markdown file at the root of your project that gives Claude Code project-specific instructions. **`AGENTS.md`** plays the same role for Codex. Both are read by the agent every time it starts a session.

<Info>
  Coddo's project-init flow generates both files and keeps them in sync. Edits made in the built-in editor write to whichever file your active provider expects.
</Info>

Common things to include:

* **Project structure** - Describe your file organization
* **Tech stack** - List frameworks, libraries, and tools
* **Conventions** - Coding style, naming patterns, file naming
* **Build commands** - How to build, test, and run the project
* **Important rules** - Things Claude should always or never do

## Using the editor

1. Click the **CLAUDE.md** icon in the sidebar
2. The editor opens as a full-screen overlay
3. Edit the markdown content
4. Changes are saved directly to the `CLAUDE.md` file in your project root

<Tip>A well-written CLAUDE.md / AGENTS.md dramatically improves your agent's output quality. The more context you give, the better the results.</Tip>

## Generate with AI

If you don't have a `CLAUDE.md` or `AGENTS.md` file yet, or if you want to start fresh, click the **Regenerate** button. Coddo will analyze your project's codebase and automatically generate complete instruction files tailored to your project — including the tech stack, file structure, conventions, and build commands.

This is the fastest way to initialize your project configuration.

## Example CLAUDE.md

```markdown theme={null}
# My Project

## Stack
- React 19 + TypeScript
- Tailwind CSS v4
- Zustand for state management

## Commands
- `npm run dev` - Start dev server
- `npm run build` - Production build
- `npm run test` - Run tests

## Conventions
- Use functional components with hooks
- Name components in PascalCase
- Use kebab-case for file names
- Always add TypeScript types

## Rules
- Never use `any` type
- Always handle errors with try/catch
- Write tests for new features
```

## Tips

* Keep it concise — the agent reads the entire file for every session
* Focus on what's unique to your project
* Update it as your project evolves
* Include examples of patterns you want Claude to follow
