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

• Third-party content exposure detected (high risk: 0.75). The required runtime workflow reads the user-provided --thread <path> JSON file (which may contain outsider-authored free text in fields like messages[].text, participants[].name, and title) and injects it into the generated HTML via generate.js (e.g., renderTextBubble → formatMessageText → escapeHTML), which Playwright then loads as file:// for screenshot rendering.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill's screenshot pipeline may run "npx playwright install chromium" at runtime (see screenshot.js) which fetches and executes browser/install artifacts from the npm registry (e.g. https://registry.npmjs.org/playwright/-/playwright-1.59.1.tgz), and Playwright/chromium are required for the renderer to produce PNGs.
