# List Shadowed By Builtin

`GET /api/skills/shadowed-by-builtin`

## Request

- Base URL: `https://app.thinqos.com` (the document declares no server; this is the origin it was published from)
- URL: `https://app.thinqos.com/api/skills/shadowed-by-builtin`
- Auth: none declared

The subject's OWN copies that now yield their slug to a built-in (TOS-6903).

A copy nobody marked as an intentional fork, installed from the platform's
first-party source (or identical to an older built-in version), no longer
runs in place of the built-in. It is kept, not deleted; this read lets the
owner see that and keep it with ``POST /{skill_id}/keep-copy``. Only copies
the subject owns are listed, because only an owner can keep one. Self or
an owner of the subject, like ``/installed-on``.
