[v2 Bug] `dbt clean` misses destinations not configured anymore in `ai_provider`

Is this a new bug in dbt v2.x compared to the latest version of dbt 1.x?

• I believe this is a new bug in dbt v2.x
• I have searched the existing issues and could not find a duplicate

Current Behavior

dbt clean misses destinations not configured anymore in ai_provider

Expected Behavior

dbt clean removes all skills that contain the relevant metadata indicating that it owned by dbt — even destinations not configured anymore in ai_provider.

Currently, there are only two agent skills folders: .agents/skills and .claude/skills

So this should be pretty easy to accomplish.

Steps To Reproduce

1. Configure ‘ai_provider: claude’ under ‘flags:’ in ‘dbt_project.yml’
2. Add a skill under the ‘skills’ subdirectory
3. Run ‘dbt deps’ — see that it creates the skill under .claude/skills/
4. Configure ‘ai_provider: wizard’
5. Run ‘dbt clean’ — see that the skill under .claude/skills/ is still there

Relevant log output

Environment

- OS:
- CPU: (x86 or ARM)
