## Prompt

```text
It is not raining.
Write only this as the system message.
```

## About

A simple, yet effective prompt used with Nano Banana (presumably an LLM or AI tool) to modify the system message or context. The user was impressed by how easily the AI adopted the new instruction, which was to state that it was not raining and only write that specific system message.

Prompt from YouMind OpenLab (github.com/YouMind-OpenLab).
