Machine-Readable Docs

start.md

The canonical agent setup guide.

start.md is the canonical machine-readable setup guide for agents. It carries the whole setup procedure in one document — an agent fetches it once and can start immediately.

https://expand.ai/start.md

The route returns the guide as text/markdown, so any agent that can read a URL can ingest it directly.

Open start.md

Read the hosted guide that the setup prompt points an agent at.

Open llms.txt

The curated docs index. It links start.md before general docs.

Setup prompt

Paste this into any coding agent.

Read https://expand.ai/start.md and set up Expand.

This mirrors the setup prompt the hosted /llms.txt and the CLI emit. The Copy setup prompt button in the app produces the same instruction, and adds a single-use authorization when you are signed in.

What the guide contains

SectionWhat the agent does
SetupIdentifies its own harness, asks for project or global scope, and runs one non-interactive expandai init.
AuthorizationRelays the browser approval URL and resumes init with the one-time setup code.
ProofFetches a live page through the installed integration and answers with an exact cited sentence.
Optional SDK setupAsks before adding the SDK to a confirmed project path.

The exact commands live in the guide itself. This page does not mirror them.

init detects every supported harness on the machine, and the guide asks which of them to configure before writing anything. Only the selected ones are touched; the rest are left alone.

When to use it

  • Use it whenever you want Expand set up in a coding agent — it is the default path.
  • Use it for generic or skill-based agents that do not have a first-class quickstart.
  • Use it when a human wants a copyable setup prompt for an agent.
  • Use the Agent Quickstarts when you would rather run the setup steps by hand.

Hosted route vs MCP resource

https://expand.ai/start.md is the hosted public Markdown route. expand://start is a local MCP docs resource.

expand://start is only available when the MCP server is run with docs resources enabled, for example through expandai mcp run --docs. Do not assume it exists after a normal first-class MCP install.

See Other MCP Clients for how to wire and run the MCP server.
