llms.txt
An /llms.txt file is a plain-text manifest at a site's root (the llmstxt.org convention) that points AI agents at key resources — the product feed, policy pages, taxonomy — so they don't have to guess. It's a voluntary signal, not a requirement.
Because it's a community convention rather than a vendor spec, its absence is not a defect — but a well-formed llms.txt is a cheap, positive signal. It's the kind of thing a product about agent-readiness should obviously publish for itself.
