Your docs still show
the old API.

What it checks

// TS2305: Module "ai" has no exported member 'AssistantResponse'.
import { AssistantResponse } from "ai";

// TS2724: Did you mean 'ToolExecutionOptions'?
import { ToolExecutionOption } from "ai";

// TS2339: Property 'reasoningDetails' does not exist...
console.log(result.reasoningDetails);

// TS2551: Did you mean 'pipeTextStreamToResponse'?
result.pipeDataStreamToResponse(res);

// TS2353: Object literal may only specify known properties...
embed({ model, value: "hello", unrecognizedFlag: true });

// TS2554: Expected 2 arguments, but got 3.

What it will not tell you

• We do not execute your code. Snippetcheck never runs the samples. It strictly type-checks them against your package's published .d.ts declarations.
• We skip what we cannot parse. Documentation is full of <YOUR_API_KEY> placeholders and ... elisions. If it isn't valid syntax, we skip it and count it in the final report tally.
• We only report provable failures. We discard noise. We do not flag undeclared variables or missing peer dependencies. Every finding we report is traced directly back to your published declarations.
