Action items

• [low] [possible mistake] providers/codeify/provider.toml:1 and providers/codeify/models/*.toml - Check: Reasoning-control API surface for an OpenAI-compatible provider. Why: All 25 models inherit reasoning = true from their base_model and every provider TOML sets reasoning_options = [], which asserts that Codeify exposes no caller-selectable reasoning control. Codeify is declared OpenAI-compatible at https://codeify.cc/v1, and the mirrored upstream models natively expose reasoning controls (OpenAI gpt-5.6/gpt-5.4 use reasoning_effort, Anthropic Claude uses effort, xAI Grok uses effort, Zhipu GLM uses a toggle). OpenAI-compatible gateways in this repo routinely forward reasoning_effort/thinking (see providers/anyapi/provider.toml and providers/alibaba-coding-plan/provider.toml, which document the exact HTTP form). The PR body cites catalog/pricing/docs pages but states nothing about reasoning request fields, so the empty-array claim is unsupported. Action: Verify against Codeify's API docs/playground whether reasoning_effort (OpenAI-style) or thinking (Anthropic-style) is accepted/forwarded for these model IDs; if so, author the matching reasoning_options and document the request syntax in provider.toml. If no control is verified, keep [] but add a brief note in the PR body (or provider.toml header comment) recording what was checked.
