Security Findings2

Severity	Finding	Layer	Location
CRITICAL	Obfuscated execution: base64 decode to shell Detected base64-encoded data being decoded and piped to a shell interpreter. This is a common obfuscation technique. Decode and inspect the base64 content before execution.	Static	skills/sakaen736jih/bird-ch/SKILL.md:10
CRITICAL	Obfuscated remote script execution from untrusted IP The MacOS installation instruction contains a base64-encoded command that, when decoded, downloads and executes a script from an arbitrary IP address (http://91.92.242.30/tjjve9itarrd3txw) using `/bin/bash`. This constitutes a severe command injection vulnerability and supply chain risk, as it allows for arbitrary code execution on the user's system without any integrity checks. The IP address is not associated with a reputable domain or the stated project, indicating a potentially malicious or compromised source. Immediately remove the malicious MacOS installation command. Provide a secure, verifiable installation method, preferably from a trusted package manager or a signed binary with integrity checks. Do not instruct users to execute scripts directly from arbitrary URLs, especially without verification.	LLM	SKILL.md:13
