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

• Third-party content exposure detected (high risk: 0.80). The skill's Advanced Patterns (references/advanced-patterns.md, "Competitor Benchmarking") explicitly instructs the agent to use a research-assistant to research 5 newsletters and pull public metrics from the open web into newsletter/competitors.md, which requires ingesting untrusted third‑party content that can influence decisions.
