AST type system for programmatic OpenAPI specification generation through AI
function calling.
This namespace defines a comprehensive Abstract Syntax Tree structure that
enables AI agents to construct complete OpenAPI v3.1 specification documents
at the AST level. Each type corresponds to specific OpenAPI specification
constructs, allowing precise control over generated API documentation while
maintaining type safety and business logic accuracy.
LANGUAGE REQUIREMENT: All description fields throughout this type system
(including operation descriptions, summaries, parameter descriptions, schema
descriptions, etc.) MUST be written exclusively in English. This is a strict
requirement for API documentation consistency and international
compatibility.
Core Purpose
The system is designed for systematic generation where AI function calls
build API specifications step-by-step, mapping business requirements to
executable OpenAPI documents. Instead of generating raw OpenAPI JSON/YAML
strings, AI agents construct structured AST objects that represent:
Complete REST API specifications with proper operation definitions
Comprehensive type schemas aligned with database structures
Detailed parameter and response body specifications
Consistent naming conventions and documentation standards
Architecture Overview
IDocument: Root container representing the entire OpenAPI specification
IOperation: Individual API endpoints with HTTP methods, paths, and data
structures
IComponents: Reusable schema definitions and security configurations
IJsonSchema: Type system following OpenAPI v3.1 JSON Schema specification
Parameters & Bodies: Request/response structures with validation rules
OpenAPI v3.1 Compliance
This implementation follows the OpenAPI v3.1 specification but is streamlined
to:
Remove ambiguous and duplicated expressions for improved clarity
Enhance AI generation capabilities through simplified type structures
Maintain developer understanding with consistent patterns
Support comprehensive API documentation with detailed descriptions
Design Principles
The generated specifications follow enterprise-grade patterns:
Consistent RESTful API design with standard HTTP methods
Comprehensive CRUD operation coverage for all business entities
Type-safe request/response schemas with validation constraints
Detailed documentation with multi-paragraph descriptions
Reusable component schemas for maintainability and consistency
Security-aware design with authorization considerations
Each generated OpenAPI document reflects real business workflows where API
operations provide complete access to underlying data models, maintain proper
REST conventions, and include comprehensive documentation suitable for
developer consumption and automated tooling integration.
