# withAttributes

▸ **withAttributes**\<`T`>(`attrs`, `fn`): `Promise`\<`T`> | `T`

Attach attributes to the current execution context so that any calls created
inside `fn` automatically inherit them. Attributes are written to the call
record on the trace server and surface in the Weave UI/filtering, so they’re
ideal for tagging runs with request IDs, tenants, experiments, etc.

Example:

```ts theme={null}
await withAttributes({requestId: 'abc'}, async () => {
  await myOp();
});
```
