🛡️ This is a Minecraft Datapack — it contains no executables or scripts outside of .mcfunction files. Some antivirus software may flag .mcfunction files as suspicious due to macro-like syntax. This is a false positive. The pack has been scanned on VirusTotal and returned clean. Only download from this official repository. Do not trust redistributed or repackaged versions from third-party sources.
