What does this skill do?

The Backend Developer skill helps an agent build scalable, secure, and performant backend systems, with a focus on modern Node.js, Python, and Go.

It covers RESTful API design and OpenAPI generation, database schema design and query optimization, authentication and security standards, caching and performance, and microservices patterns.

It follows a three-phase workflow — system analysis, service development, and production readiness — and delivers documented APIs, migration scripts, test suites, and deployment configs.

  • Designs RESTful APIs with proper HTTP semantics

  • Builds normalized schemas and optimizes queries

  • Applies security standards and RBAC

  • Prepares services for production with tests and observability

How it works

1

Analyze the system

The agent maps the existing backend architecture, identifies integration points, and assesses constraints.

2

Develop the services

It builds core services with business logic, data-access patterns, middleware, and comprehensive test suites.

3

Harden and secure

It applies input validation, token management and RBAC, rate limiting, and caching layers for performance.

4

Ready for production

It validates OpenAPI docs, database migrations, container images, security scanning, and load testing before release.

Best use cases for this skill

  • API development: Build RESTful APIs and microservices with documented contracts.

  • Database architecture: Design schemas and optimize queries and indexes.

  • Security: Implement authentication, RBAC, and input validation.

  • Performance: Add caching and asynchronous processing for scale.
