WHAT IT DOES

What crow_browser_extract_article does on Crow

AI agents invoke crow_browser_extract_article to trigger actions in Crow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why crow_browser_extract_article is rated High

This tool actively runs a stealth browser, executes page loads across multiple external services (including paywall-bypass services like 12ft.io), and processes the results. This is an external operation whose effects depend on arguments, placing it firmly in Execute. The paywall-bypass capability adds reputational/legal risk, raising severity to medium.

From the tool's definition 'loaded IN the stealth browser' and 'trying a fallback ladder: live page → archive.today → Wayback → 12ft.io' — triggers external browser operations and network requests to multiple external services
