Copy as Markdown

The Copy as Markdown action fetches the page’s .md source and writes it to the clipboard. The user gets the raw markdown body — the same content served by the markdown route — without leaving the page.

When to use it

• Pasting docs context into an LLM chat that doesn’t have URL prefill.
• Quoting an authoritative version of a page in a PR or issue.
• Feeding markdown into local tooling (note-taking apps, scripts, etc.).

Configuration

copyMarkdown is on by default. To disable it:

starlightLlmActions({
  actions: {
    copyMarkdown: false,
  },
})

When disabled, the action is removed from the dropdown.

How it works

The action runs entirely in the browser:

1. The dropdown item resolves the page’s markdown URL using markdownUrl (default /{slug}.md).
2. A fetch() request retrieves the markdown.
3. The response body is written to the clipboard via the Async Clipboard API.

If the user’s browser blocks clipboard writes (e.g. on http:// origins without explicit permission), the action falls back to selecting the markdown into a hidden textarea and using document.execCommand('copy').

Modifying what gets copied

The action copies whatever the markdown route serves. To change the copied content, point markdownUrl at a different route:

starlightLlmActions({
  markdownUrl: '/raw/{slug}.txt',
  injectRoute: false, // your route already serves the content
})

See markdownUrl and injectRoute for the full options.
