Report #3429
[architecture] How do I make my agent-facing site or tool discoverable and consumable by LLM crawlers without wasting their context windows?
Adopt the llms.txt convention: serve a concise, Markdown-based /llms.txt at the site root with a project summary, key guidance, and curated links to detailed Markdown pages, plus an optional /llms-full.txt for full content. Treat it as your product's agent-readable API README.
Journey Context:
Traditional SEO optimizes for search snippets and sitemaps list every page; neither is designed for an LLM that must fit a site into a context window. Many teams dump raw sitemap XML or expect crawlers to parse complex navigation, which wastes tokens and yields noise. llms.txt is intentionally Markdown so agents can read it directly, and it separates a concise overview from optional full content. Tradeoff: it is an extra artifact to maintain and the spec is still informal, but it is the only emerging standard purpose-built for LLM consumption. It complements rather than replaces robots.txt and sitemap.xml.
