RFD: Add Agent Skills List proposal

[ignatov]

Proposes a mechanism for agents to advertise available skills to clients, aligned with the Agent Skills Specification (https://agentskills.io/specification).

Introduces:

• AvailableSkill type with name, description, license, compatibility, and allowedTools fields
• AvailableSkillsUpdate session notification

Seems reasonable. If I understand correctly, this is solely for informational purposes to the client to show the user?
At this stage, there would be no management of the skills available from the client?

What about enabling the client to forward additional locations of some skills folders to the agent, say at session creation, similar to how the client can forward a collection of MCP servers for the agent to use. Maybe the IDE has its own skills folders. Maybe the user wrote their own skills folder they would like to use across different agents.

How would it work when Skills are acting as Slash Commands? Does the Agent decide to put them in the Slash Command or not?

Recently, that is what has been happening, deprecating "Slash Commands" per se, and just have metadata in the skills to allow such direct activation.

Second, I am guessing the intention here is to do something like @skillname along with /skillname?
