gh-stack

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

• Third-party content exposure detected (medium risk: 0.30). Source SKILL.md describes a GitHub CLI workflow (gh stack view --json, gh stack sync) that reads remote PR/stack state (e.g., open/queued PRs and status) from GitHub, which can include outsider-authored PR text.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly directs installing the GH extension at runtime with "gh extension install github/gh-stack", which fetches and installs remote code (github/gh-stack) that will execute locally as a required dependency.
