Skills storage location is not switchable (web migrate_skill_storage → 501; no CLI/TUI control)

[SaladDay]

Summary

The Skills storage location setting (CC Switch default ~/.cc-switch/skills vs ~/.agents/skills) is surfaced in the settings UI but is not actually switchable on any surface. In the web console it even errors.

Details

• Web (cc-switch web serve): the frontend calls invoke("migrate_skill_storage", { target }), but that command is not wired in the web bridge — it is left commented out in src/web/handlers/skills.rs, so it falls through to HTTP 501 Not Implemented. Selecting a different location throws / shows an error toast instead of migrating.
• CLI: there is no subcommand to view/set/migrate the skills storage location.
• TUI: there is no setting for it in the interactive Settings screen.
• Backend model: the skills SSOT base directory is effectively hardcoded to get_app_config_dir()/skills in src/services/skill.rs (honors CC_SWITCH_CONFIG_DIR only). ~/.agents/skills is only a read-only discovery/import source, not a configurable target, and there is no skill_storage_location field in AppSettings (src/settings.rs).

Impact

• Web users see the option and get a 501 error on click.
• CLI/TUI users have no way to change it at all.
• This is inconsistent with the desktop UI, which presents the option as if it were functional.

Suggested resolution (pick one)

1. Implement it for real: add an AppSettings field for the skills storage location + a working migrate_skill_storage command, and wire it across web/CLI/TUI; or
2. Drop the option from the UI if ~/.cc-switch/skills (under CC_SWITCH_CONFIG_DIR) is the only supported location.

Note

In the web build the control has been temporarily hidden to avoid the 501 until this is resolved.
