Bug Fixes

• #11813 Document the generated auto decorator accessors, so libraries re-exporting them satisfy

api-extractor's ae-undocumented rule. get* and set* accessors carry the description of the decorator they read or write; is* accessors get a generic one, since a decorator description does not describe a boolean check.

/** Check if the `@TypeSpec.GraphQL.inputType` decorator was applied on the given target. */
export function isInputType(program: Program, target: Model): boolean {
return hasAutoDecorator(program, "TypeSpec.GraphQL.inputType", target);
}

/** Mark a model as a GraphQL input type in the emitted schema. */
export function setInputType(program: Program, target: Model): void {
setAutoDecorator(program, "TypeSpec.GraphQL.inputType", target);
}

• #11813 Honor the library's own tspconfig.yaml when generating signatures and reference documentation, so

libraries that opt into a compiler feature (such as auto-decorators) no longer report errors during gen-extern-signature and doc.

• #11561 gen-extern-signature now generates signatures for sub path exports. Each export with a typespec condition is compiled on its own, entities are attributed to the export that first reaches their source file, and the generated files are written under a directory matching the sub path with $decorators imported from that same sub path.

// generated-defs/streams/MyLib.Streams.ts-test.ts
import { $decorators } from "my-lib/streams";
import type { MyLibStreamsDecorators } from "./MyLib.Streams.js";

const _decs: MyLibStreamsDecorators = $decorators["MyLib.Streams"];
