Starlight Skills Configuration

You can configure starlight-skills behavior using options in your astro.config.ts.

Minimal setup (all defaults):

starlightSkills()

Monorepo — output the collocated skills folder to the repository root instead of the docs package root:

starlightSkills({
  collocatedDir: '../../skills',
})

Well-known only — skip committing files to Git; rely solely on public hosting for skill discovery:

starlightSkills({
  outputMode: 'well-known-endpoint',
})

Custom URL root — host skill pages under /agent-skills/ instead of /__skills/:

starlightSkills({
  skillsRoot: 'agent-skills',
  sidebarLabel: 'Agent Skills',
})

Plugin Options

targetLocale

Determines which locale to recognize skills from when using Starlight's i18n features.

• If specified, only pages inside the target locale's content directory will be processed as skills.
• Default: Derived from Starlight's default locale.

outputMode

Controls where compilation artifacts (SKILL.md, index.json, etc.) are written.

• 'well-known-endpoint': Exports files exactly to dist/.well-known/skills/. This makes skills discoverable via a public URL immediately after deployment.
• 'collocated': Exports files exactly to <projectRoot>/skills/. This commits skills into your repository for usage without deployment.
• 'both' (Default): Exports to both destinations.

collocatedDir

Output directory for collocated (and both) output mode. Accepts a path relative to the Astro project root, or an absolute path. Useful in monorepos where the project root is not the repository root. Default: 'skills'

autoGeneratePages

Controls what additional UI the plugin injects into your Starlight documentation site.

autoGeneratePages?: {
  skill?: boolean;    // Generates the dedicated AI view page
  catalog?: boolean;  // Generates the visual listing page (Catalog)
}

Default: { skill: true, catalog: true }

(Note: dynamically generated pages are tagged with <meta name="robots" content="noindex"> to prevent SEO duplicate content issues against your origin pages.)

skillsRoot

The base URL path where all dynamic pages (catalog, skill view pages, subfile explorer) reside. Default: '__skills'

catalogCategoryDisplay

How nested categories are displayed on the visual Catalog.

• 'nested' (Default): Subcategories sit within parent category sections.
• 'flat': Renders exact full-path strings (e.g., development/frontend).

autoCategoryMode

Determines how skills are automatically bucketed into categories when skill-category is absent.

• 'path' (Default): Categories are auto-derived from the file system directory structure relative to the content root.
• false: Disables auto-derivation.

(Note: When 'path' is used alongside i18n locales, the locale subdirectory is automatically stripped from the category pathway).

sidebarLabel

Customizes the text label for the "Skills" group which is automatically injected into the Starlight Sidebar. Default: 'Skills'
