AI agents invoke pinchtab_select to trigger actions in Pinchtab. 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.
This tool triggers a browser interaction (selecting a dropdown option) that can cause side effects depending on the page context — such as triggering form submissions, filtering data, or changing application state. It's a browser action whose effects depend on arguments, fitting the Execute category. Severity is medium because the impact varies by context but can change application behavior.
From the tool's definition Select an option in a <select> dropdown by its ref ID. Pass the option value or visible text.
