+<Purpose>
+Enumerates all schematics provided by @schematics/angular with full option metadata (types, defaults, enums, prompts, required flags).
+</Purpose>
+<Use Cases>
+* Discover generators available before planning code changes.
+* Inspect required options for a schematic prior to execution.
+* Provide intelligent suggestions to users based on option types and prompts.
+</Use Cases>
+<Operational Notes>
+* Resolution uses Node's module loader. If a schematic collection cannot be resolved, this tool returns an empty list.
+* Hidden/private schematics are included for transparency.
+* Use 'run_schematic' to actually execute a schematic after reviewing options here.
+ * Official docs: https://angular.dev/tools/cli/schematics and https://angular.dev/cli/generate
