browserous/browserous Execute Risk 3/5

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke new_page to trigger processes or run actions in Browserous - Instant Browser for Your Agent. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON NEW_PAGE

new_page can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.
