What
The reload_skills response the CLI sends now includes a builtin: true field on each skill entry whose resolved name matches one of Claude Code's own bundled skills.
The schema describing an available skill or command gained an optional builtin boolean, true only for Claude Code's own built-in commands, used to decide which command a bare /name invocation runs when a user, project, plugin, and MCP command all share the same name.
Why
This removes ambiguity when a skill or command name collides with one of Claude Code's own: it's now possible to tell that a /name invocation is running the built-in version rather than a same-named user, project, plugin, or MCP one.
