## Returns

`Promise`<`string`>

## Remarks

transformers.js chat templates take a `tool`-role message whose `content` is a string. A
`SpooledArtifact` result renders as a HANDLE (metadata + the forged `artifact_*` tools to read it)
when its `ToolCall.inline === false` — the secure default — and inline via `asString()` only when a
producer opted into `inline: true`. Applies the trust envelope and degrades Media to text.
