LLMs

Petit makes your documentation directly consumable by large language models and AI agents through several machine-readable endpoints. In dev mode the endpoints always work, served on demand by Vite middleware without any configuration. In production (build), they are generated as static files only when you set siteUrl, because the absolute cross-links inside them require a known base URL.

Every endpoint is emitted with two extensions. The .txt form follows the llms.txt spec convention, and the .md form is provided for agents and tools that expect a markdown extension. Cross-links match the extension of the file they live in: .txt files link to other .txt files, and .md files link to other .md files.

llms.txt and llms.md

A machine-readable index of all documentation pages, served at /llms.txt and /llms.md. It lists every non-draft page with a link to its individual raw markdown file:

# My Project

> My Project documentation

This file lists all documentation pages for My Project.
For the full documentation in a single file,
see: https://docs.example.com/llms-full.txt

## Docs

- [Overview](https://docs.example.com/getting-started/overview.txt)
- [Configuration](https://docs.example.com/getting-started/configuration.txt)

The .md variant is identical except its links point to llms-full.md and the .md per-page files.

llms-full.txt and llms-full.md

All documentation concatenated in sidebar order into a single file, served at /llms-full.txt and /llms-full.md. This is useful for feeding an entire documentation site into an LLM context window.

Petit also adds an alternate link tag in the HTML head of every page, pointing browsers and crawlers to the full markdown file:

<link rel="alternate" type="text/markdown"
	  href="/llms-full.md" />

Individual page endpoints

Every documentation page is available as raw markdown at both /{slug}.md and /{slug}.txt. For example, https://docs.example.com/getting-started/overview.txt serves the raw markdown for the overview page, prefixed with the page title and description as a heading and blockquote. This prefix is carried through to the built files from each page's frontmatter, so production output matches dev.
