Overview
Per-action permission checks create more interruptions but keep the operator involved in consequential actions. Full access is faster but allows the agent to make broad local changes. Browser automation is useful only when the operator is comfortable allowing the agent to control the browser.
External tools also add dependencies. They may require credentials, permissions, service availability, and configuration. A tool-enabled workflow is therefore more capable than a text-only workflow, but it has more operational surfaces that can fail.
