extract-openapi-from-code

To extract an OpenAPI spec from FastAPI or NestJS code, the skill requires a working project with installable dependencies, then uses runtime export or static extraction to automatically generate the specification document from your codebase.

Yes, you can generate swagger documentation from a Django or Flask API codebase by extracting the OpenAPI specification directly from the code, which enables API documentation workflows and SDK generation without writing the spec manually.

The OpenAPI extraction process works with Spring Boot and Rails frameworks, covering both runtime export and static extraction across multiple popular frameworks including Hono and Laravel to validate and align the generated spec with your codebase.

The best way to get a single OpenAPI document for multiple services in a monorepo is to extract the OpenAPI spec from each service's code, validating and aligning the generated specifications to enable unified SDK generation and API documentation.

Yes, you need installable dependencies in a working project before extracting an OpenAPI specification from code, because the extraction process requires a functional environment to accurately perform runtime export or static extraction and validate the output.

After extracting an OpenAPI spec, you should validate and align the generated specification with your codebase to ensure accuracy, which directly enables downstream SDK generation and API documentation workflows.
