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

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.90). The skill's command examples and workflows (e.g., SKILL.md and references/advanced-workflows.md) explicitly run GitHub CLI commands like `!`gh pr view $1 --json title,body,author,files`` and `!`gh pr diff $1 --name-only` which fetch user-generated PR content from GitHub that the agent is expected to read and act on, enabling indirect prompt injection risk.
