Markdown and llms.txt

Every page on signo's website has a version written for agents: the same content as Markdown, without navigation or styling.

You want	Ask for
A page as Markdown	its path plus `.md`, such as `/docs/quickstart.md` or `/trust.md`; the home page is `/index.md`
The same, from the page's own address	the page with `Accept: text/markdown`
An index of the docs	`/llms.txt`
All the docs in one file	`/llms-full.txt`
To see what agents see, in a browser	the Agent button at the top of any page, which adds `?view=agent`

Responses that depend on Accept carry Vary: Accept. HTML pages point to their Markdown with <link rel="alternate" type="text/markdown"> and a matching Link header. Links inside the Markdown are absolute, and links between docs point at their Markdown versions, so an agent can follow them without parsing HTML.

A prompt for your coding agent

Paste this into any coding agent that can read a web page:

Replace "Sign in with Google" in this app with signo. Read https://usesigno.co.uk/llms.txt, then follow the guide for this app's auth library. I'll add the site at https://usesigno.co.uk/account/sites and put the client ID and secret in .env myself; don't ask me to paste the secret into chat.

The home page's "Copy prompt" button copies the same prompt, with the address of the copy of signo you are on.
