 ### Fixes
 
+- Ollama/Kimi Cloud: apply the Moonshot Kimi payload compatibility wrapper to Ollama-hosted Kimi models like `kimi-k2.5:cloud`, so tool routing no longer breaks when thinking is enabled. (#41519) Thanks @vincentkoc.
 - Models/Kimi Coding: send the built-in `User-Agent: claude-code/0.1.0` header by default for `kimi-coding` while still allowing explicit provider headers to override it, so Kimi Code subscription auth can work without a local header-injection proxy. (#30099) Thanks @Amineelfarssi and @vincentkoc.
 - Security/plugins: disable implicit workspace plugin auto-load so cloned repositories cannot execute workspace plugin code without an explicit trust decision. (`GHSA-99qw-6mr3-36qr`)(#44174) Thanks @lintsinghua and @vincentkoc.
 - Moonshot CN API: respect explicit `baseUrl` (api.moonshot.cn) in implicit provider resolution so platform.moonshot.cn API keys authenticate correctly instead of returning HTTP 401. (#33637) Thanks @chengzhichao-xydt.
