Ollama's /v1/chat/completions silently ignores extra_body.think (it only honours it on /api/chat — ollama/ollama#14820), so agent.reasoning_effort: none never actually disabled thinking on OpenAI-compatible Ollama routes. Emit the top-level reasoning_effort='none' field (which Ollama respects) alongside think=False (kept for proxies and the native /api/chat path). The PR's second half (propagating reasoning_config to the background-review fork) already landed on main via agent/background_review.py, so only the provider-profile change is salvaged here, resolved onto the current GLM/effort-aware profile. Salvaged from PR #29820 by @Epoxidex.

"""Custom / Ollama (local) provider profile.

Covers any endpoint registered as provider="custom", including local

|
Ollama instances and OpenAI-compatible reasoning endpoints (GLM-5.2 on

|
Volcengine ARK, vLLM, llama.cpp). Key quirks:
|
|
- ollama_num_ctx → extra_body.options.num_ctx (local context window)
|
|
- reasoning_config disabled → top-level reasoning_effort="none"
|
|
(Ollama /v1/chat/completions ignores think=False — ollama#14820)
|
|
+ extra_body.think = False for /api/chat and proxies
|
|
- reasoning_config enabled + effort → top-level reasoning_effort
|
|
(the native OpenAI-compatible format GLM/ARK expect; unset omits it
|
|
so the endpoint's server default applies)
