# 6. Stay In Your Lane

Fable 5 is proactive. Sometimes that means it drafts the email, changes the file, or fixes the thing when you only wanted an opinion.

**When to use:** Use when you want analysis and advice, not action. Especially anywhere it can touch real systems, files or messages.

## The prompt

```
When I am describing a problem, asking a question, or thinking out loud rather than requesting a change, the deliverable is your assessment. Report your findings and stop. Do not apply a fix until I ask for one. Before taking any action that changes real state, check that the evidence actually supports that specific action.
```

**Why it works:** It draws a clean line between advising and acting, which is exactly the line you want with a model this capable.
