The ephemeral-vs-structured framing makes a lot of sense. One gap I keep running into in practice is discovery itself. Skills get found through progressive discovery within a single agent session, and MCP tools get found through ToolSearch or server registration. But there's no standard way for an agent to discover which skills or MCP servers exist across the broader ecosystem. You end up with each host app maintaining its own curated list.
With MCP v2.1 adding Server Cards at .well-known endpoints, there's at least a crawlable surface for MCP servers now. Skills don't have anything equivalent yet. Do you think Skills will eventually need their own registry or discovery mechanism, or does the lightweight file-based approach make that unnecessary?
With Agent Skills there are the Claude marketplace for discovery and that is being indexed by several skill directories. There is also the Vercel skill installer. As Skills are ephemeral and are not hosted like MCP which is why repositories make more sense. People are trying, there are directories out there. But as you said Skills are so easy to set up and in many ways very specific to your needs that maybe there is less of a need for a directory or discovery?
