 - If Moonshot publishes different context limits for a model, adjust
   `contextWindow` accordingly.
 - Use `https://api.moonshot.ai/v1` for the international endpoint, and `https://api.moonshot.cn/v1` for the China endpoint.

+## Native thinking mode (Moonshot)
+
+Moonshot Kimi supports binary native thinking:
+
+- `thinking: { type: "enabled" }`
+- `thinking: { type: "disabled" }`
+
+Configure it per model via `agents.defaults.models.<provider/model>.params`:
+
+```json5
+{
+  agents: {
+    defaults: {
+      models: {
+        "moonshot/kimi-k2.5": {
+          params: {
+            thinking: { type: "disabled" },
+          },
+        },
+      },
+    },
+  },
+}
+```
+
+OpenClaw also maps runtime `/think` levels for Moonshot:
+
+- `/think off` -> `thinking.type=disabled`
+- any non-off thinking level -> `thinking.type=enabled`
+
+When Moonshot thinking is enabled, `tool_choice` must be `auto` or `none`. OpenClaw normalizes incompatible `tool_choice` values to `auto` for compatibility.
