Backend Development Skill

Atomic skill for backend development including API creation, authentication, and service implementation.

Responsibility

Single Purpose: Implement backend services, APIs, and business logic

Actions

create_endpoint

Create a new API endpoint with validation and error handling.

// Input
{
  action: "create_endpoint",
  runtime: "nodejs",
  framework: "express",
  api_style: "rest"
}

// Output
{
  success: true,
  code: "router.post('/users', validate(schema), async (req, res) => {...})",
  files: [
    { path: "routes/users.ts", content: "..." },
    { path: "routes/users.test.ts", content: "..." }
  ],
  api_spec: { openapi: "3.0.0", paths: {...} },
  security_notes: ["Rate limiting recommended", "Input validation applied"]
}

implement_auth

Implement authentication and authorization.

build_service

Build a business logic service.

integrate_external

Integrate with external APIs.

Validation Rules

function validateParams(params: SkillParams): ValidationResult {
   (!params.) {
     { : , :  };
  }

   (params. ===  && !params.) {
     { : , :  };
  }

   { :  };
}
