WHAT IT DOES

What ira_new_tab does on IRA-RESEARCHER

AI agents invoke ira_new_tab to trigger actions in IRA-RESEARCHER. 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.

WHY IT NEEDS A POLICY

Why ira_new_tab needs a policy

Opening a new tab and navigating to a URL is an Execute action because it triggers external operations (browser state changes, network requests, page loads) whose effects depend on the URL argument. While not destructive or financial, it can be misused to redirect to phishing sites, malicious content, or trigger unwanted downloads.

From the tool's definition Tool name 'ira_new_tab' with description 'Open a new tab (optionally navigate to a URL)' — this triggers a browser action that executes navigation with externally-supplied arguments.
