Function completable

completable<T extends StandardSchemaV1<unknown, unknown>>(
schema: T,
complete: readonly (string | number | boolean)[] | CompletionCallback,
): CompletableSchema<T>
Make a schema field completable so clients can request autocomplete suggestions via completion/complete.

Pass an array of allowed values for case-insensitive prefix matching, or a callback for dynamic/contextual suggestions.

Accepts any Standard Schema field (StandardSchemaV1); zod shown in the example. Apply refinements like .describe() to the schema argument, not to the completable result: refinements that clone the schema (as zod's do) silently drop the SDK's completion marker. .optional() is the one exception — the SDK unwraps optionals when looking for completions.
Type Parameters
- T extends StandardSchemaV1<unknown, unknown>
Parameters
- schema: T
- complete: readonly (string | number | boolean)[] | CompletionCallback
Returns CompletableSchema<T>
Example
```
schema: z.object({
  language: completable(
    z.string().describe("The programming language"),
    ["python", "typescript", "go"]
  ),
})
```
