Type Alias: OutputSchemaStrategy

OutputSchemaStrategy = "instruct" | "tool-forced"

Defined in: src/core/outputSchema.ts:88

How the schema reaches the model.

• 'instruct' (default) — the shape is described in the system prompt and the model is asked for JSON. Works on every provider, because it is only words. • 'tool-forced' — the shape is presented as a synthetic tool and the provider's tool choice is FORCED to it, so generation is constrained at the source instead of requested in prose. Requires a provider that declares carriesForcedToolChoice; a provider that does not is refused BY NAME at run start rather than quietly downgraded, because a strategy that silently falls back to the other one is config that lies.
