How to validate .rbi files in Python

Python 
def is_rbi(file_path: str) -> bool:
    """Check if file is a valid RBI by magic bytes."""
    signature = bytes([0x42, 0x4C, 0x49, 0x32, 0x32, 0x33])
    with open(file_path, "rb") as f:
        return f.read(6) == signature

How to validate .rbi files in Node.js

Node.js 
function isRBI(buffer: Buffer): boolean {
  const signature = Buffer.from([0x42, 0x4C, 0x49, 0x32, 0x32, 0x33]);
  return buffer.subarray(0, 6).equals(signature);
}

How to validate .rbi files in Go

Go 
func IsRBI(data []byte) bool {
    signature := []byte{0x42, 0x4C, 0x49, 0x32, 0x32, 0x33}
    if len(data) < 6 {
        return false
    }
    return bytes.Equal(data[:6], signature)
}
