Interface: AdapterCapabilities

Defined in: packages/core/src/types/adapter.ts:29

Hints about what an adapter supports. Every field is optional; an adapter may omit the whole capabilities object, and consumers should treat omission as 'unknown — assume the feature works and handle errors if it doesn't'.

This is an additive extension to the Adapter contract (ADR 0001) — adapters without capabilities remain fully compliant. Consumers that care (router / ensemble adapters, UI that hides the tool toggle when the provider can't use tools) can read the hints.
