+### Feature: inline lambda tool definitions
+
+Developers can now define tools directly at the call site using `ToolDefinition.from(...)` with typed lambda handlers and `Param.of(...)` parameter metadata — no separate annotated class required. Async variants (`fromAsync`) and `ToolInvocation` context injection (`fromWithToolInvocation`) are also available. ([#1895](https://github.com/github/copilot-sdk/pull/1895))
+
+```java
+ToolDefinition greet = ToolDefinition.from(
+    "greet", "Greets a user by name",
+    Param.of(String.class, "name", "The user's name"),
+    name -> "Hello, " + name + "!");
+```
+
+### Other changes
