/kind bug
What this PR does / why we need it:
Follow-up to #1896.
Anthropic Messages requests (
/v1/messages) failed tokenization against thevLLM
/renderendpoint when the request carriedtools. The router forwardedAnthropic-shaped tool definitions (
{name, description, input_schema})verbatim, but vLLM's OpenAI-compatible
/renderexpects the function schema(
{type: "function", function: {name, description, parameters}}), so itrejected the request with HTTP 400 (
Field required: body.tools[0].function).This broke the token-producer path and, in turn, precise-prefix-cache routing
for Claude Code traffic.
MessagesToRenderChatRequestnow maps Anthropic custom tools into the OpenAIfunction schema (
input_schema->parameters, nested underfunction).Tools that are already OpenAI-shaped (carry a
functionfield) or are notobject-shaped pass through unchanged.
