Method fetchResourceManifest

internal/metadata/refresh.go:461–488

fetchResourceManifest downloads the resource's source repo and reads its manifest, returning both the content and the manifest path relative to the repo root (e.g. "skills/foo/SKILL.md"). The relative path lets callers show users where the content came from. Failures return empty strings so callers

// detail view still renders the indexed metadata without the manifest body.
