# Multi-threading

> Understand how Aomi separates a conversation into durable parent and child threads while preserving context, authority, and transaction review.

A thread is a durable conversation with its own messages, working state, and
execution context. Your main thread carries the conversation you see. When a
request needs focused work, Aomi can create a child thread for that work and
return its result to the parent.

This is not operating-system multi-threading. Aomi threads are persistent agent
workspaces. They can be restored after an interruption and continued with the
same context. The boundary also keeps unrelated work from being mixed into one
conversation history.

## Parent and child threads

```mermaid theme={null}
sequenceDiagram
    actor U as You
    participant P as Parent thread
    participant C as Child thread
    participant W as Wallet policy
    U->>P: Request
    P->>C: task(work order)
    C->>C: Call tools, build, and simulate
    C-->>P: Final message and staged summary
    alt More work is needed
        P->>C: task(agent_id, follow-up)
        C-->>P: Updated result
    else The result is ready
        P->>W: commit_staged
    end
```

The parent gives the child a complete work order. It can select an App, activate
the relevant skills, and provide an initial chain context. The child then works
in its own transcript. When it finishes, the parent receives the child's final
message and a system-produced summary of any staged transactions.

The parent can continue the same child by its `agent_id`. A continuation keeps
the child's original App, skills, chain context, and lineage. This prevents a
follow-up from silently changing the identity or capability of an existing
child.

## A child narrows authority

A child receives enough account and wallet context to perform its assigned
work. It does not receive every capability of the parent.

* It can read data, call its App's tools, build transactions, and simulate them.
* It cannot sign or submit a transaction. The parent must review the staged
  result and call `commit_staged`.
* It cannot create another foreground child or schedule asynchronous work.
* It cannot request, revoke, or expand wallet authorization.
* If the parent is read-only, the child remains read-only.

These rules apply to both EVM and SVM work. A child may prepare either kind of
transaction, but the signature boundary remains in the parent thread and the
selected [wallet policy](/docs/security/permission-model).

<Note>
  A child can propose a transaction, but it cannot turn that proposal into an
  onchain side effect. The parent receives only staged work that has reached a
  terminal simulation result.
</Note>

## Threading does not imply parallel execution

Each thread processes one active turn at a time. This makes the transcript and
working state deterministic within that thread.

Foreground `task` calls are also serial. The parent waits for one child to
finish before it evaluates the result or starts the next delegated action. You
can create separate children for independent work, but their results return to
the parent in the order the parent runs them.

Use a child thread when you need a separate specialist, a different App, or a
clean work context with a result returned to the current conversation. Use an
[asynchronous task](/docs/concepts/asynchronous-tasks) when the work should start
without making the current conversation wait.

## Choosing the right boundary

| Goal                                                           | Use                                    |
| -------------------------------------------------------------- | -------------------------------------- |
| Continue the current discussion with the same context          | The current thread                     |
| Delegate focused work and wait for the result                  | A foreground child with `task`         |
| Follow up with the same specialist and preserve its transcript | `task` with the existing `agent_id`    |
| Start independent work without waiting for an inline result    | `spawn_thread`                         |
| Run work later or when a condition becomes true                | `schedule_cron` or `wake_on_condition` |
