Generate a complete, spec-correct llms.txt file from structured input — the generator counterpart to this server's checkers. You supply the site name, a one-paragraph summary and optional sections of curated links; the tool renders canonical llms.txt markdown: an H1 with the site name, a blockquote summary, then one H2 per section with '- [name](url): description' link bullets. The result is returned as ready-to-publish text (serve it at https://yourdomain.com/llms.txt as plain text) plus structured metadata (byte size, section/link counts). llms.txt is the curated site map AI systems read first — Shopify serves one natively, and AI-readiness scanners (including agent_readiness_scan and check_wellknown_discovery on this server) check for it. Pure function: no network calls, deterministic, free, unlimited within fair use.
