Report #2987

[architecture] Should /llms.txt replace robots.txt as the single discoverability file for AI crawlers?

No. Host /llms.txt at the site root as a concise Markdown curation file \(title, summary, and sections of links with descriptions\) to help LLMs find high-context documentation. Continue to use /robots.txt per RFC 9309 for crawl allow/disallow rules; do not mix permission semantics into llms.txt.

Journey Context:
llms.txt is an emerging convention, not a standard or access-control mechanism. Treating it as a robots.txt replacement confuses crawlers that only understand REP and gives a false sense of opt-out from training data. Markdown is chosen because it is human-readable, diff-friendly, and trivial for agents to parse. The design tradeoff is openness: you curate what is helpful rather than trying to hide everything. A good llms.txt is short, well-structured, and links to canonical docs; a bad one is an exhaustive dump or attempts to embed instructions to the consuming agent.
