CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). This is a raw install.sh hosted in a GitHub user repo — running such remote shell scripts without reviewing them is high risk because they can execute arbitrary commands and the account/repo may not be trusted or well-known.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The skill's runtime install step can execute a remote script via curl -fsSL https://raw.githubusercontent.com/stjbrown/env-garden/main/install.sh | sh (which fetches and pipes code to a shell) and the CLI is treated as a required dependency if eg is not on PATH.
