📚 Description

ChatGPT, Claude, and other MCP apps can find a Skill through the MCP server, and get_skill already returns its SKILL.md text in markdown. Every instruction still led with runCommand, which a chat app cannot run, so an agent there had no stated way to use the Skill.

The get_skill description, the MCP section of /agent.md, and the skilld-registry Skill now say the same thing. Without a shell, the agent follows markdown for the session, after it names the Skill and its source repository. The files beside SKILL.md are listed in files, not included.

The CLI stays the lead path. A chat-app run gets SKILL.md only, with no supporting files and no approval stop for Skill behaviors.

use a Skill without a shell: follow the markdown field for the session.
