Forward Responses API requests natively to the upstream /responses endpoint. Kimi Code retains no responses: previous_response_id is rejected with an invalid-request error and store=true is pinned to false. Preserve completed_at, store, and input_tokens_details.cache_write_tokens in Responses payloads.

This adds cache_write_tokens to the public usage model, but the checked-in schemas in docs/openapi.json and cmd/gomodel/docs/docs.go still omit it. Generated clients and API consumers therefore cannot discover or model a value that runtime Responses payloads now expose. This is non-blocking, but the generated API documentation should be refreshed.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
Artifacts
- Python checker authored for this validation; it parses the checked-in JSON schema and inspects the generated Go schema definition, showing whether cache_write_tokens is publicly exposed.
- Captured output of the executed checker from /home/user/repo with exit code 0; it confirms the source field exists while both public schemas omit it.
cache_write_tokens, completed_at, and store are now part of the public Responses schema (Greptile P2).

Expose cache-write tokens at the Responses usage wire path.
core.PromptTokensDetails adds cache_write_tokens, but core.ResponsesUsage uses prompt_tokens_details. The usage test expects the field at input_tokens_details.cache_write_tokens, so the generated Responses schema does not match the required wire path. Correct the Responses usage schema without changing the chat usage path, then regenerate the schemas. Apply the same correction to docs/openapi.json.

@coderabbitai Plan for this finding — WDYT?
- Flip the
ResponsesUsagestruct tags ininternal/core/responses.goto the Responses wire keys:input_tokens_details/output_tokens_details. The wire format is already correct via the customMarshalJSON/UnmarshalJSONinusage_json.go— only the swag-generated schema reads the struct tags, so this aligns schema with wire without touching runtime behavior. make swaggerregeneratescmd/gomodel/docs/docs.go+docs/openapi.json.- Chat usage path unchanged:
core.Usagekeepsprompt_tokens_details/completion_tokens_details. One caveat:core.PromptTokensDetailsis a shared type, socache_write_tokenswill also appear as an available property in the chat usage schema — unavoidable without splitting types; chat wire output is unchanged. Splitting the type seems disproportionate here.
Locally verified so far: full unit suite with -tags=contract (CI mirror) + e2e suite green.

@weselben, your plan addresses the finding. ResponsesUsage.MarshalJSON already emits input_tokens_details and output_tokens_details. Changing only the ResponsesUsage struct tags should align the generated schema with that wire format without changing runtime output.
Keep core.Usage as-is. I agree that splitting core.PromptTokensDetails is unnecessary for this fix. After make swagger, check that both generated files show input_tokens_details.cache_write_tokens for Responses usage and retain the chat usage keys. Your reported test results cover runtime behavior; the generated schema still needs that check.
Thanks for the clarification.

Learning: In GoModel, `internal/core/usage_json.go` defines custom JSON marshaling for `core.ResponsesUsage` that emits `input_tokens_details` and `output_tokens_details`, independently of the struct tags in `internal/core/responses.go`. Swag uses those struct tags to generate the Responses usage schema. Chat `core.Usage` in `internal/core/types.go` retains `prompt_tokens_details` and `completion_tokens_details`; both usage types share `core.PromptTokensDetails`.

The new Kimi Code provider tests create upstreams directly with httptest.NewServer, including the native Responses, streaming, continuation-rejection, and base-URL cases. This violates the repository directive requiring provider tests to use providertest.JSONServer, SSEServer, or RouteServer and inspect their captures. The repository requirement must be satisfied before merging.
