check-skill-registration

Verify built-in skills registration by comparing skills installed via `install_skill()` against managed sets in `check_claude_dir()`. This ensures workspace management commands like `wsp rm` and `wsp rename` do not incorrectly flag built-in skills as user-generated content.

Built-in skills are flagged as user-generated content when they are not registered within the `managed` and `managed_dirs` sets in `check_claude_dir()`. Extracting skill names from `install_skill()` calls and comparing them confirms proper registration and prevents these errors.

The best way to check for missing registrations is to extract skill names from `install_skill()` calls and compare them against the `managed` and `managed_dirs` sets. This also confirms the parent `skills/` directory exists in `managed_dirs`.

Run a skill registration verification check after adding a new built-in skill. This confirms the new skill is correctly accounted for in the managed sets, preventing potential issues during workspace cleanup operations.

Workspace management requires the parent `skills/` directory to be registered in `managed_dirs`. Confirming its existence ensures the system correctly tracks built-in skills and prevents incorrect flags during workspace cleanup.

You can detect missing built-in skills by comparing the extracted names from `install_skill()` calls against the `managed` and `managed_dirs` sets in `check_claude_dir()`. This identifies any missing registrations for skills.
