architect-create-client-tool

Use when the user wants the agent to trigger something in their own browser, app, or SDK during a call (navigate a page, open or close a dialog, read on-screen context, run client-side code), or asks "how do I add a client tool", "make the agent do something in my app", or reports a client tool that won't save or where the agent never gets a response back. For a server API tool see the create-webhook-tool skill; for editing an existing tool see the edit-existing-tool skill.
