Fixes

🔧 Prompt caching restored — Fixed Zod schemas silently stripping cache_control fields from Anthropic requests (#74)

Without .passthrough() on nested schemas, fields like cache_control: { type: "ephemeral" } were removed before forwarding to the API. This caused all requests to be billed as uncached, significantly increasing token costs.

Also in this release

  • Added .passthrough() to OpenAI schemas for consistency (preserves name, tool_calls, audio fields)
  • Added regression tests for both providers
