name: llm-seo-readiness description: >- Validates Aptos docs changes for LLM consumption (llms.txt, curated feeds, Markdown exports, HTML→Markdown) and for SEO (metadata, sitemap, robots, structured data). Use when adding or restructuring docs, editing llms routes or curation, changing Head/meta/OG, updating robots.txt or sitemap behavior, or when the user mentions LLMs.txt, AI tool ingestion, crawlers, discoverability, or SEO.

LLM and SEO readiness (Aptos docs)

LLM / machine-readable

• Frontmatter: Every new or renamed doc needs accurate title and description in English; they surface in /llms.txt and .md exports. Mirror updates in src/content/docs/zh/ per agent guidelines (Spanish es/ is out of scope for agent-maintained docs).
• Curated lists: If a page should appear in the LLM index or early in full corpus, update src/lib/llms-curated-ids.ts (LLMS_INDEX_SECTIONS, LLMS_SMALL_DOC_IDS, FULL_PRIORITY_DOC_IDS as appropriate). Build fails if an id is missing from English non-draft docs.
• Index copy: User-facing explanations live in src/content/docs/llms-txt.mdx, src/content/docs/build/ai.mdx, and the Chinese zh/ counterparts—keep URLs and feed names aligned with src/pages/llms-index.ts.
• HTML → Markdown: Shared logic is src/lib/llms-html-sanitize.ts. When minifying for llms-small.txt, collapse spaces/tabs only—never all \s (newlines must survive for fenced code and Markdown structure).
• Route wiring: Custom handlers are swapped in via src/integrations/llms-txt-index.ts; endpoint implementations live under src/pages/llms-index.ts, src/pages/llms-small.txt.ts, src/pages/llms-full.txt.ts.
• Robots: public/robots.txt should stay consistent with sitemap URL and, when feeds change, the commented LLMs.txt pointers at the bottom.

SEO

• Per-page metadata: Starlight frontmatter title / description feed OG, Twitter, and schema in src/starlight-overrides/Head.astro—avoid empty or placeholder descriptions on public pages.
• Sitemap: Produced by @astrojs/sitemap in astro.config.mjs; ensure new top-level routes or major URL changes still make sense for indexing.
• Hreflang / alternates: Head override builds language alternates from SUPPORTED_LANGUAGES—new locales need config updates, not only content folders.
• Draft / hidden content: Do not rely on curated LLM ids or public sitemap for content that must stay off production; follow existing draft filtering in the .md pipeline and curation tests.

Verification

After substantive changes:

pnpm test tests/llms-curated-ids.test.ts tests/llms-html-sanitize.test.ts
pnpm lint && pnpm check

For full coverage: pnpm test and a production pnpm build when touching routes or integrations.
