# FORGE_API_MISSING

The file has no FORGE_API line.

## What happened

Every file declares the Forge API level it was written for, so an engine that changes later can still read it as it was meant.

## What to do

Add `FORGE_API = 1` on the first lines of the file.

## Example

```text
strategy.py, line 1: FORGE_API is missing: put FORGE_API = 1 on the first lines of the file [FORGE_API_MISSING]
```

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