What it does
When you ask an AI agent to build or change a Node.js/Express/TypeScript backend, this skill gives it a set of house rules to follow. The agent will put route definitions in thin route files, move logic into controllers, services and repositories, validate input with Zod, read settings from a unifiedConfig module instead of process.env, and report errors to Sentry. The skill is only reference material (markdown guides and code examples); it does not run anything itself.
Great for
- Backend developers on Node.js/Express/TypeScript teams who want consistent code structure
- Teams using Prisma, Sentry and Zod who want an agent to follow their conventions
- Developers migrating older Express code toward a layered architecture
Skip it if
- Projects on a different stack (Python, Go, Django); the guide says to adapt the principles yourself, and the examples will not match
- Teams whose conventions differ from these patterns (for example, not using unifiedConfig or BaseController), since the agent may impose code that does not fit their codebase
Try asking
- “Add a new REST endpoint for managing user subscriptions, following our controller and service layers”
- “Refactor this Express route file so business logic moves into a service with dependency injection”
- “Set up a new microservice skeleton with instrument.ts, unifiedConfig and Sentry error handling”
- “Write Jest unit and integration tests for this repository class”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Point the agent at your own project's conventions too; the guide is written for one example microservice layout and may conflict with your existing structure.
- Check generated code against the referenced files, since examples such as BaseController and unifiedConfig must exist in your project to compile.
- Review any Sentry and config changes, because the examples show patterns that send error data to a third-party service and rely on environment-specific settings.
