CLI surface for toggling per-project support for Cursor rules, Cursor skills, Claude Code skills, and Claude Code subagents. The underlying persistence lives in Settings.ExternalConfigs; this module is the user-facing entry point.

Four sources are supported: cursor:rules, cursor:skills, claude:skills, claude:agents. All default to disabled; enabling any source opts the selected project into discovery of the matching files from both the user's home directory and the project source root.
