# <>…</>

Group AML values without adding text, scheduling, capability scope, or a runtime resource boundary.

A JSX fragment (`<>…</>`) returns its children directly. Use it when a component needs to contribute several authored values without inventing a wrapper primitive.

```tsx
import { Agent, AmlRuntime, System } from "@aml-jsx/sdk"
import { DeterministicAgentProvider } from "@aml-jsx/sdk/testing"

function ReviewInstructions() {
  return (
    <>
      <System>Be concise and evidence-first.</System>
      Review the authorization change.
    </>
  )
}

const runtime = new AmlRuntime({ agentProvider: new DeterministicAgentProvider() })
const result = await runtime.evaluate(
  <Agent>
    <ReviewInstructions />
  </Agent>
)
```

The automatic JSX transform imports `Fragment` from `@aml-jsx/sdk/jsx-runtime`; application code normally does not import it by hand.

## Semantics

- Children are resolved and concatenated in authored order.
- `<>…</>` inserts no separators or prompt text of its own.
- It creates no Agent, Sandbox, Workspace, capability, trace, or cleanup boundary.
- It does not start siblings concurrently. Use [`<Parallel>`](https://agent-markup-language.com/docs/reference/primitives/parallel/) for independent text-producing branches, or `Promise.all()` around component-local [`evaluate()`](https://agent-markup-language.com/docs/reference/runtime/#component-local-evaluation) calls when JavaScript needs each result.
- Descriptor placement still follows the eventual containing boundary. A `<System />` or `<Tool />` inside `<>…</>` still belongs to its nearest [`<Agent />`](https://agent-markup-language.com/docs/reference/primitives/agent/).

An explicit `<Fragment>…</Fragment>` form is also exported, but shorthand fragments are the conventional authoring form. See [AST and evaluation](https://agent-markup-language.com/docs/ast/) for renderable values and node construction.
