CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). These are raw .sh/.ps1 installer scripts from an individual GitHub repo that the skill instructs you to execute directly via curl|bash or irm|iex — a common high-risk pattern for malware distribution unless you have verified the repo and inspected the scripts.

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.85). The skill’s runtime workflow fetches and executes outsider-authored free text from public GitHub raw URLs (e.g., curl ... https://raw.githubusercontent.com/yldgio/copilot-devcontainer/... | bash / irm ... | iex), which can be ingested as readable script text by the agent during execution.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill runs remote-install commands at runtime that fetch and execute code (e.g., npx github:yldgio/copilot-devcontainer, curl -fsSL https://raw.githubusercontent.com/yldgio/copilot-devcontainer/main/install.sh | bash, and irm https://raw.githubusercontent.com/yldgio/copilot-devcontainer/main/install.ps1 | iex), so external content is executed and required.
