# Give it to your agent

> Three ways to hand content from Context Atlas to a coding agent - a prompt, a link or Markdown - and when to use each.

## The prompt from /agent

[/agent](https://contextatlas.dev/agent) has one sentence to paste into Claude Code, Codex, Cursor or any agent with web access. Pick the mode first:

- **I have a project:** run it inside your repository. The agent detects the stack, tells you what it found, then loads the matching sources.
- **I'm starting something new:** describe what you want to build. The agent proposes a stack, explains the trade-offs and sets it up once you agree.

The prompt only points to [/llms.txt](https://contextatlas.dev/llms.txt). The real instructions live there, so they stay current without you changing the prompt.

```text
Read https://contextatlas.dev/llms.txt and follow its instructions for an existing project: detect the stack of this repository, tell me what you found, then load the matching sources and follow their best practices.
```

## Links

Agents fetch plain-text URLs reliably. Paste a link into the chat, or put it in your project's `AGENTS.md` or `CLAUDE.md` so every session sees it.

| To give the agent… | Paste |
| --- | --- |
| The whole catalog with instructions | `https://contextatlas.dev/llms.txt` |
| The sources of one tool | `https://contextatlas.dev/llms/<id>.txt`, such as `https://contextatlas.dev/llms/stripe.txt` |
| The catalog and all docs at once | `https://contextatlas.dev/llms-full.txt` |
| One docs page | The page URL with `.md`, such as `https://contextatlas.dev/docs/mcp.md` |
| Structured data for a script | `https://contextatlas.dev/atlas.json` or the [JSON API](https://contextatlas.dev/docs/api) |

Prefer the topic files over the whole catalog when you know your stack. They are small and leave room in the context for the vendor docs themselves.

A line for `AGENTS.md`:

```markdown
Before working with a tool from our stack, fetch its sources from https://contextatlas.dev/llms/<id>.txt (ids: nextjs, drizzle, vercel) and follow them.
```

## Markdown

Every docs page has a Markdown version: add `.md` to its URL, or use the link at the bottom of the page. Every docs page also announces it with `<link rel="alternate" type="text/markdown">`, so agents that read a page's head find it on their own.

## MCP instead

If your agent supports MCP, connecting the [MCP server](https://contextatlas.dev/docs/mcp) is usually better than links: the agent searches and fetches only what it needs, without you choosing files.
