# Routing

Atlas One routing chooses a thinking mode before generating the final prompt.

## Routing Flow

```text

```

## Route Preview

A route should explain:

- reason for selection
- recommended output shape
- suggested next action

## Non-goals

- No hidden execution
- No model-only authority
- No automatic tool use
- No unsafe prompt-injection patterns
