Your AI agent is capable.
It just doesn't have a process.

Without a system, every project starts from zero. No structure, no quality bar, no way to carry context between sessions. The Dev System gives your agent a complete methodology — research, plan, build, score, audit, deploy. Personalised to your stack.

What is OpenAPI Spec?

An OpenAPI specification is the industry-standard way to describe REST APIs. It defines every endpoint, parameter, request body, response schema, and authentication method in a structured YAML or JSON format that both humans and machines can read.

Why AI agents need it

AI coding agents use OpenAPI specs to understand exactly how your API should work. Instead of guessing endpoint structures or response formats, the agent follows your spec precisely—generating correct routes, validation, type definitions, and even client SDKs.

  • Complete endpoint definitions with paths and methods
  • Request/response schemas with full type information
  • Authentication and security scheme definitions
  • Parameter validation rules and constraints
  • Example requests and responses for testing
  • Compatible with Swagger UI and code generators
