Add an HTTP endpoint to an existing module — updates the audience-scoped controller (creates one if needed), DTO, service method, and i18n keys for any new error messages. Triggers: "add an endpoint", "expose endpoint X on module Y", "add a route to <module>", "/add-endpoint".

Add a TypeORM entity to an existing module — entity file, repository, TypeOrmModule.forFeature registration, generated migration. Triggers: "add an entity", "add a table", "add <Entity> to module X", "/add-entity".

Add mirrored Arabic + English translation keys to src/infrastructure/i18n/translations/{ar,en}/<feature>.json, then regenerate translation-keys.ts via npm run i18n:sync. Triggers: "add a translation", a Translator.tr('<key>') call without a matching JSON key, "/add-i18n-keys".

Generate a new role-scoped controller for an existing module (e.g. admin-foo.controller.ts next to user-foo.controller.ts). Wires @Protected(Role.X), the path/version, and registers in the module. Triggers: "expose this module to admins/users", "add an admin controller for <module>", "/add-protected-controller".

Diagnose and break a circular dependency between NestJS modules or providers — without reaching for forwardRef. Triggers: Nest "circular dependency" / "can't resolve dependencies" startup error, "ModuleA imports ModuleB and back", a new cross-module service injection, "how do I avoid a cycle", "/circular-deps".

Apply when writing, reviewing, or removing comments. Triggers: /comments, "should I comment this", "is this comment good", "explain why this code does X".

Generate or update a Postman Collection v2.1.0 JSON for a single module. The collection lives at `src/modules/<module>/postman/<module>.postman_collection.json`. Triggers "generate postman collection for X", "/generate-postman-collection <module>".

Scaffold a feature module under src/modules/<plural>/ — entity, repository, service, audience-scoped controllers, DTOs, i18n stub, AppModule wiring. Triggers: "create a new module", "scaffold feature X", "/init-feature-module", new domain entity with API surface.

Source of truth for naming — folders, files, classes, methods, DTOs, DB tables/columns/indexes, HTTP paths, i18n keys, migrations. Use when creating, renaming, or reviewing names. Triggers "/naming-conventions", "rename", "is this name correct".
