# One prompt serves people and agents

> For agents: start with the [agent guide](https://ratstack.sh/llms.txt). Every page is Markdown by default; add `Accept: text/html` for HTML.

Free workshop: [how to burn a trillion tokens and get good results](/tokenmaxx#interested).

## What it does

- `/prompts` lists published prompts.
- Each detail page shows the full prompt, a copy control, and its credit.
- Markdown is the default representation. Browsers request HTML.
- `listPrompts` and `getPrompt` expose the same source through capability projections.

## The standard

- `.brain/resources/prompts/` owns the source. The content build owns derived assets.
- Title, description, and body must contain text. Validation reports independent failures together.
- Core owns the `PromptLibrary` port. Content and CLI adapters supply it.
- The public catalogue requires no identity or mutable database record.
- Existing Worker infrastructure serves the assets. No prompt execution or scheduling occurs here.
- Foldkit Messages and Commands own clipboard interaction. Prompt text remains unchanged.

## How to check

1. Run the full check, test, and build gate.
2. Open `/prompts/hill-climb` and copy its text.
3. Disable JavaScript. Read the full prompt and its credit.
4. Request `/prompts` without an HTML Accept header. Check the Markdown list.
5. Call `listPrompts`, then call `getPrompt` with a returned slug.
6. Check that an unknown slug returns `UnknownPrompt`.
