Combine the supported chat surface with explicit evidence workflows.
Practical procedure
- Start a chat turn when the client needs a direct response to supplied messages. Keep the client’s chosen conversation history explicit.
- When the answer must depend on project evidence, retrieve Knowledge passages or use an approved research plan and inspect its findings.
- Return the answer together with the actual supporting references your application retained. Use a durable work order when execution must outlive the interactive request.
Call the supported chat contract
Normal web chat and the customer CLI use GoCux Gateway. Provider routing stays inside the service. The model catalog advertises the GoCux route alias gocux-deep, not an upstream provider identity. A compatible chat client supplies its message history and an explicit data-classification header; GoCux applies identity, policy, paid admission and credit reservation before a provider request.
Contract example
Developer examples below describe routes on an authorized, configured GoCux control-plane base URL. They are request shapes or operation references, not claims that a particular public hostname exposes the API. Use the workspace for the corresponding human workflow; availability and permissions depend on the actual deployment.
POST /v1/chat/completions X-GoCux-Data-Classification: public Content-Type: application/json
{
"model": "gocux-deep",
"messages": [
{
"role": "user",
"content": "Summarize these supplied public notes."
}
],
"stream": false,
"max_completion_tokens": 512
}Inspect the result
Read the returned choices and handle an error response before showing a completed answer. When streaming, consume complete events and distinguish connection closure from a successful terminal result. GoCux route aliases are product contracts; do not let a client-selected upstream model bypass server routing or display provider identities as customer configuration.
What to keep explicit
GoCux does not establish a /v1/responses endpoint here. This is a workflow migration guide, not a base-URL substitution for a Responses SDK.
Handle incomplete and refused work
Declare X-GoCux-Data-Classification exactly once. A data_classification field in the chat-completions body is rejected rather than used as the declaration. Missing classification is unclassified and can be refused by policy. An optional Idempotency-Key helps identify an operation, but a paid replay can return 409 without replaying the original response or contacting the provider again.
