# updateSkillData

> Write data under this skill's namespace into a FunctionResult.

Writes data under this skill's namespace into a `FunctionResult` object.
This persists skill state across tool invocations by embedding it in the
agent's global data.

## **Parameters**

**`result`** `FunctionResult` — required

The FunctionResult to update with the skill's namespaced data.

---

**`data`** `Record<string, unknown>` — required

The data to store under this skill's namespace.

---

## **Returns**

`FunctionResult` -- The updated FunctionResult with the skill data merged in.

## **Example**

```typescript {4}
import { SkillBase } from '@signalwire/sdk';

// Inside a tool handler, persist skill state
const updatedResult = mySkill.updateSkillData(result, {
  lastQuery: 'New York',
  cachedResponse: { temp: 72, conditions: 'sunny' },
});
```
