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

• Third-party content exposure detected (high risk: 0.75). SKILL.md:165-166 instructs the agent to read and summarize the outsider-authored CHANGELOG.md from the installed gstack repository ($INSTALL_DIR/CHANGELOG.md), which is fetched/updated from GitHub at runtime (Step 4 for vendored installs), so its free-form text can enter the LLM context.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill performs a runtime git clone from https://github.com/garrytan/gstack.git and then runs ./setup, which fetches remote code during execution and runs it locally.
