+# check-scopes
+
+Validates that the DB enum `api_key_scope` contains every `<resource>:<action>` derived from `coderd/rbac/policy/RBACPermissions`.
+
+- Exits 0 when all scopes are present in `coderd/database/dump.sql`.
+- Exits 1 and prints missing values with suggested `ALTER TYPE` statements otherwise.
+
+## Usage
+
+Ensure the schema dump is up-to-date, then run the check:
+
+```sh
+make -B gen/db   # forces DB dump regeneration
+make lint/check-scopes
+```
+
+Or directly:
+
+```sh
+go run ./tools/check-scopes
+```
+
+Optional flags:
+
+- `-dump path` — override path to `dump.sql` (default `coderd/database/dump.sql`).
+
+## Remediation
+
+When the tool reports missing values:
+
+1. Create a DB migration extending the enum, e.g.:
+
+   ```sql
+   ALTER TYPE api_key_scope ADD VALUE IF NOT EXISTS 'template:view_insights';
+   ```
+
+2. Regenerate and re-run:
+
+   ```sh
+   make -B gen/db && make lint/check-scopes
+   ```
+
+3. Decide whether each new scope is public (exposed in the catalog) or internal-only (handled by the catalog task).
