# UNKNOWN_HOOK

A method whose name starts with on_ is not a Forge hook.

## What happened

A method whose name starts with `on_` is read as a hook. This one is not a hook Forge has.

## What to do

Rename it, or schedule it with `@fg.every` or `@fg.on`. When the name is close to a hook, the message suggests it.

## Example

```text
strategy.py, line 27: `on_signal` is not a Forge hook. Rename it, or schedule it with @fg.every or @fg.on. [UNKNOWN_HOOK]
```

The wording of the message depends on your file, and the code does not. An error stops the file from loading.
