In short

An agent can read llms.txt, fetch any page as markdown and use llms-full.txt for all the text at once. A Harness app publishes its own llms.txt and ai.json. This page is for people building or onboarding agents.

## How an agent starts.

Read

### Fetch llms.txt.

It lists every page and product in groups, with a link to the markdown version of each.

Read

### Fetch a page as markdown.

Add .md to any page address, or use llms-full.txt for the text of every page at once.

Act

### Use the Cloud section of Praecise Spaces or Harness.

A person or an agent with access to a project can deploy it from the Cloud section of Praecise Spaces.

## Point an agent at the site.

Two addresses are enough to begin.

```
curl https://praecise.cloud/llms.txt
curl https://praecise.cloud/llms-full.txt
```

A Harness app serves its own llms.txt and ai.json, so another agent can read what it does.
