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

• Third-party content exposure detected (high risk: 0.90). SKILL.md explicitly instructs the agent to fetch and read GitHub issue content (Phase 1: "GitHub Issue: Fetch details from issue number" and "When issue number is provided: Fetch issue details with gh issue view <number>"), which is user-generated, untrusted third‑party content that the agent will interpret and could influence subsequent actions.
