# Generating Api Sdks
## Overview
This skill provides automated assistance for api sdk generator tasks.
This skill provides automated assistance for the described functionality.
## Prerequisites
Before using this skill, ensure you have:
- API design specifications or requirements documented
- Development environment with necessary frameworks installed
- Database or backend services accessible for integration
- Authentication and authorization strategies defined
- Testing tools and environments configured
## Instructions
1. Use Read tool to examine existing API specifications from {baseDir}/api-specs/
2. Define resource models, endpoints, and HTTP methods
3. Document request/response schemas and data types
4. Identify authentication and authorization requirements
5. Plan error handling and validation strategies
1. Generate boilerplate code using Bash(api:sdk-*) with framework scaffolding
2. Implement endpoint handlers with business logic
3. Add input validation and schema enforcement
4. Integrate authentication and authorization middleware
5. Configure database connections and ORM models
1. Write integration tests covering all endpoints
See `{baseDir}/references/implementation.md` for detailed implementation guide.
## Output
- `{baseDir}/src/routes/` - Endpoint route definitions
- `{baseDir}/src/controllers/` - Business logic handlers
- `{baseDir}/src/models/` - Data models and schemas
- `{baseDir}/src/middleware/` - Authentication, validation, logging
- `{baseDir}/src/config/` - Configuration and environment variables
- OpenAPI 3.0 specification with complete endpoint definitions
## Error Handling
See `{baseDir}/references/errors.md` for comprehensive error handling.
## Examples
See `{baseDir}/references/examples.md` for detailed examples.
## Resources
- Express.js and Fastify for Node.js APIs
- Flask and FastAPI for Python APIs
- Spring Boot for Java APIs
- Gin and Echo for Go APIs
- OpenAPI Specification 3.0+ for API documentation
This skill generates client SDKs in multiple languages from OpenAPI specifications. It automates code scaffolding, schema-aware models, authentication hooks, and test stubs so teams can ship client libraries quickly.
The skill reads an OpenAPI 3.0 specification, extracts endpoints, models, and security schemes, and produces language-specific client code and documentation. It scaffolds request/response types, HTTP helpers, error wrappers, and authentication middleware, then emits tests and example usage. Outputs follow a predictable layout so you can integrate the generated SDK into CI/CD and package registries.
What input formats are supported?
OpenAPI 3.0+ specifications (JSON or YAML) are required. Ensure the spec includes schemas and security schemes for best results.
Can I customize code style or templates?
Yes. The generator supports template overrides so you can adapt naming, packaging, and idiomatic patterns per language.
