No Agent Skills index
An Agent Skills index is a file, published at /.well-known/agent-skills/index.json, that lists reusable skills or capabilities an AI agent could load directly from your site. This check found no such file. It's a very new, emerging standard, so almost no sites publish one yet, which is why this is flagged as informational rather than a real gap. Because adoption is still so early, not having this index costs you nothing today; very few AI agents look for it yet. The only relevance is forward-looking: if your business does, or will, publish reusable AI-facing skills or workflows, being an early adopter here is a visibility edge over competitors who haven't considered it at all. Your developer needs 1-2 hours, only if this applies to you. If you publish agent skills, serve /.well-known/agent-skills/index.json listing each one with its name, description, URL, and a sha256 checksum (a code that verifies the file hasn't been tampered with). If you don't offer agent skills, there's nothing to do here.
