NestJS Skills: Professional Software Engineering

A free, MIT-licensed agent skill for designing, implementing, refactoring, debugging, reviewing and verifying NestJS and TypeScript software. It covers feature work, bug fixes, APIs, libraries, testing, maintainability, developer experience and idiomatic syntax.

Start by inspecting repository instructions, the working tree, manifests, installed versions, relevant source, callers, contracts and existing checks. Preserve unrelated changes and current public behavior unless a breaking change is explicitly authorized.

Choose the smallest coherent implementation and version-compatible syntax using repository conventions, installed types and source, and official documentation. Syntactic sugar should improve clarity without hiding meaningful effects, cost, failures or lifecycle.

Verify changes with risk-appropriate focused and broader tests, type checking, lint and formatting checks, builds and practical smoke checks. Report the checks actually run and distinguish verified results from assumptions or unrun checks. Review and diagnosis requests remain read-only unless implementation is authorized.

Included references cover syntax and idioms, syntactic sugar and API ergonomics, and implementation verification.
