CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). These are direct downloads of executable installer scripts (.ps1 and .sh) hosted as GitHub Release assets from an individual/unknown account and are a high‑risk pattern (executable releases from small/unknown repos, commonly abused to distribute malware).

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

• Third-party content exposure detected (high risk: 0.75). The required workflow installs and then runs grep-app-cli to search public GitHub repositories, and the tool’s matched file contents (outsider-authored code/comments from arbitrary repos) are ingested as readable text into the agent’s runtime context/output, creating an indirect prompt-injection surface.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill includes runtime install commands that fetch and directly execute remote scripts (PowerShell: irm https://github.com/sudosubin/grep-app-cli/releases/latest/download/grep-app-cli-installer.ps1 | iex, and shell: curl https://github.com/sudosubin/grep-app-cli/releases/latest/download/grep-app-cli-installer.sh | sh), which executes remote code during runtime.
