Anthropic Messages API nests `disable_parallel_tool_use` inside the `tool_choice` object (per docs.claude.com/parallel-tool-use). The local Anthropic-compat endpoint dropped that flag because the OpenAI shape it translates into uses a different name and lives at the top level instead. SDK clients (anthropic-python, anthropic-sdk-go, etc.) that already speak this dialect therefore could not opt out of parallel tool calls against the local GGUF model. Extract `disable_parallel_tool_use` from the incoming tool_choice and invert it to `parallel_tool_calls` on the agentic-loop call. Plain-chat and existing tool_choice shapes are untouched. Added a focused unit test that pins the dict/None/bool/string boundary cases.

"""End-to-end routing tests for the new sampling parameters.
|
|
|
|
Pins the per-provider gating contract added by the
|
|
expose-sampling-params PR: each of `frequency_penalty`, `seed`, `stop`
|
|
/ `stop_sequences`, `service_tier`, `parallel_tool_calls` only appears
|
|
on the outbound body when the upstream provider actually accepts it.
|
|
|
|
The provider matrix is captured per docs:
|
|
- Anthropic Messages: accepts stop_sequences, service_tier
|
|
(auto|standard_only), disable_parallel_tool_use (inverted). REJECTS
|
|
frequency_penalty, seed, logprobs (silently dropped client-side).
|
|
- OpenAI Chat Completions (default OAI-compat branch): accepts every
|
|
field; OpenAI cloud uses `max_completion_tokens` rather than
|
|
`max_tokens`.
|
|
- OpenAI Responses (gpt-5.x / o3): rejects temperature, top_p,
|
|
frequency_penalty, seed, stop, logprobs. Accepts service_tier
|
|
(auto|default|flex|priority) and parallel_tool_calls.
