What problem does it solve? Editing the Nodefony backend core without full context leads to memory leaks, blocking event-loop code, broken DI wiring, and contract drift between backend and frontend. This Skill loads the verified rules, recipes, and API references before the first backend code modification, so changes respect performance budgets, TypeScript strictness, and structural conventions. ## Core Features & Use Cases - Absolute rules enforcement: lazy allocation, listener cleanup, zero synchronous I/O in the pipeline, ALS binding for deferred listeners, and mandatory memory-suite gates before committing pipeline changes. - Verified recipes and API references: on-demand references/ files covering core (Service, Container, Kernel, CLI commands), HTTP pipeline (Context, sessions, TLS), framework (Router, Controller, decorators, admin data plane), ORM, pagination contracts, and realtime. - Full-stack contract coordination: pairs with the frontend skill so data-plane endpoints, page contracts, realtime channels, and shared types stay synchronized across back and front. - Use Case: When asked to add an injectable service, a CLI command, an HTTP/WS endpoint, or an ORM entity in the Nodefony repository, load this Skill first to get the exact decorator signatures, lifecycle hooks, and quality gates instead of re-exploring the source tree. ## Quick Start Load the nodefony-framework-dev skill before editing any Nodefony backend code, then follow its recipe for the specific task such as creating a service, controller, or CLI command.
