Cloudflare published a draft RFC proposing /.well-known/skills/index.json as a standard endpoint for coding agents to discover agent skills on any domain. The RFC builds on RFC 8615 and uses progressive disclosure: agents fetch a lightweight index (~100 tokens per skill), load full SKILL.md instructions when relevant, and pull supporting scripts on demand.
Agent skills today are scattered across GitHub repos, documentation sites, and social media. There's no standard way to answer "what skills does this domain publish?" Cloudflare reuses a proven web standard rather than building new infrastructure - if adopted, any domain could expose its skills for automatic discovery.
The RFC is at Draft v0.1 - Cloudflare is seeking community feedback before the specification solidifies.
