# Discover agents that have a skill tagged `tag`. Access-scoped like `list`

> Discover agents that have a skill tagged `tag`. Access-scoped like `list`
(superuser → all; otherwise owner ∪ public ∪ user-grant — see
`agent_access_predicate`). Uses the GIN `idx_agent_skills_tags` via the `@>`
containment operator and `EXISTS` (no join fan-out / DISTINCT).
