+## `postToolUse` output
+
+The `postToolUse` hook can modify the tool result or inject additional context for the model by writing a JSON object to stdout.
+
+```typescript
+{
+    modifiedResult?: {
+        resultType: "success";
+        textResultForLlm: string;
+    };
+    additionalContext?: string;
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `modifiedResult` | object | Replacement tool result. Must have `resultType: "success"`. If returned with `resultType: "failure"`, the failure routes downstream and `postToolUseFailure` fires next. |
+| `additionalContext` | string | Additional guidance appended to `textResultForLlm` so the model sees it after the tool output on the same turn. When multiple hooks return `additionalContext`, the results are joined with a double newline and capped at 10 KB. |
+
+Return `{}` or empty output to keep the original successful result.
+
+> [!NOTE]
+> `modifiedResult` is honored by both SDK programmatic hooks and command/HTTP config-file `postToolUse` hooks.
