WHEN AI AGENTS USE THIS TOOL

AI agents invoke takeAppScreenshot to trigger processes or run actions in BrowserStack. 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 TAKEAPPSCREENSHOT

takeAppScreenshot 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.

browserstack.yaml 
tools:
  takeAppScreenshot:
    rules:
      - action: allow
        rate_limit:
          max: 10
          window: 60
        validate:
          required_args: true

How do I enforce a policy on takeAppScreenshot?

Can I rate-limit takeAppScreenshot?

Yes. Add a rate_limit block to the takeAppScreenshot rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block takeAppScreenshot completely?

Set action: deny in the Intercept policy for takeAppScreenshot. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
