INVOKE BEFORE editing Ash resources/actions/policies/notifiers.
Use when
Files under *_ash/ or lib/**/ash/**.
Adding actions, attributes, or policies.
Checklist
Keep resources thin: validations in changes, logic in actions, side-effects in notifiers.
Authorization: define policies per action; default deny; use bypass? false.
Queries: preload related data in queries to avoid N+1; use calculations instead of manual Enum maps.
Changes: prefer change set_attribute/change manage_relationship over custom code.
APIs: expose minimal public actions; avoid direct Repo access from controllers.
Warnings to emit
Direct Repo calls from controllers bypassing Ash APIs.
Missing policy for custom actions.
Large after_action blocks doing IO; move to notifiers/observers.
