The package @biomejs/cli-linux-x64-musl contains an embedded executable file named package/biome. While the presence of an executable warrants careful review, the package is published by a project with significant stars and forks, and it has verified SLSA provenance. Given this context, the embedded executable is likely a legitimate part of the CLI tool and not indicative of malicious intent. Without stronger evidence, I cannot classify this package as malware.
