Description

Kimi Code now applies protocol-specific request behavior for subscription and API-key models. K3 keeps the direct API's 131K output default, uses low/high/max reasoning effort with high as the default, and omits temperature. K2.7 Code sends preserved thinking instead of reasoning_effort and carries reasoning context through tool-result continuations.

The generic OpenAI-compatible handler exposes narrow request and message-conversion hooks so Kimi Code can customize these fields without duplicating the full request pipeline. Discovered server capacity still overrides local fallback metadata without guessing a protocol for unknown future model IDs.

Test Procedure

Run pnpm test and pnpm check-types from the repository root. The provider and fetcher suites include wire-level coverage for all four model IDs, temperature omission, custom effort, OAuth retry, server metadata overrides, and preserved thinking across a tool-result plus trailing-text continuation.

Additional Notes

PR #1325 correctly fixes Kimi K3 through OpenRouter, whose 32,768-token upstream cap differs from the direct Kimi Code API. This PR intentionally keeps the direct provider's 131,072-token output default.

Current step: Resolve the merge conflicts. The review sequence resumes after the branch is mergeable.

Review-state labels are managed by this workflow; do not edit them manually. community-approved is managed the same way — do not add or remove it manually. It signals a fresh community code approval for the current head as an advisory priority only; maintainer review is still required.
