What issue are you seeing?

In the Codex CLI, the $ skill mention/selector UI shows duplicate entries when a skill with the same name exists in multiple scopes (e.g., REPO and USER). This is confusing because skill precedence says the higher-precedence location should override the lower one, but the selector provides no indication which entry wins or which one will run when selected.

Note: /skills looks fine in my case — the issue is specifically the $ selector.

What steps can reproduce the bug?

1. Create a skill in the repo scope:
   • <repo>/.codex/skills/my-skill/SKILL.md
   • with:

     ---
     name: my-skill
     description: test
     ---

2. Create another skill in the user scope with the same name:
   • ~/.codex/skills/my-skill/SKILL.md
   • with the same YAML name: my-skill
3. Start Codex CLI from inside the repo.
4. Type $ to open the skill mention/selector UI.
5. Observe that two my-skill entries are shown.

What is the expected behavior?

When multiple skills share the same name, the $ selector should either:

• Show only the resolved/active skill (the one that wins precedence), or
• Show both entries but clearly label them with:
  • which one is Active (wins precedence)
  • which one is Overridden
  • and include scope + full path so the user can intentionally choose.

Current behavior (duplicates with no disambiguation) makes explicit invocation ambiguous.
