Error message

${colors.bold(normalizePath(path.relative(fileURLToPath(contentPaths.contentDir), fileURLToPath(event.entry))))} must live in a ${colors.bold('content/...')} collection subdirectory.

What it means

During content type generation (astro sync or dev-server events), a file under src/content could not be assigned a collection because it sits directly in the content root instead of a collection subdirectory (src/content/<collection>/...). Astro warns with the relative path and returns shouldGenerateTypes: false, so no types are generated for that file.

Solutions

1. Move the file into a collection subdirectory (src/content/<collection>/file.md)
2. Or relocate it outside src/content entirely (e.g. src/docs/)
3. Delete the file if it is stray

Example fix

# before
src/content/README.md

# after
src/content/blog/contributing.md   (or move it out: src/docs/README.md)

// Lint: no content-type files directly under src/content
import { readdirSync, statSync } from 'node:fs';
const CONTENT_EXTS = ['.md', '.mdx', '.json', '.yaml', '.yml'];
const strays = readdirSync('src/content').filter(
  (f) => statSync(`src/content/${f}`).isFile() && CONTENT_EXTS.some((ext) => f.endsWith(ext)),
);
if (strays.length > 0) throw new Error(`Files must live in a collection subdirectory: ${strays.join(', ')}`);

When it happens

Trigger: Placing a stray .md/.mdx/.json file directly in src/content/ rather than inside a named collection folder; leftover notes or template files dropped into the content root.

Common situations: Documentation or README files accidentally saved into src/content; misunderstanding that every entry must belong to a named collection subdirectory.
