What problem does it solve? Setting up Agent Whiteboard involves installing a Go CLI, choosing a publishing server, configuring origin trust, and starting a local Page Agent broker, with many ways to break existing configuration or provider state. This Skill guides an agent through exactly the setup mode the user needs while preserving existing configuration and credentials. ## Core Features & Use Cases - Mode-scoped setup: Installs the CLI and verifies an existing or local publishing server, or configures Page Agent with origin trust and a foreground or managed-daemon broker, only when requested. - State protection: Inspects and merges existing YAML configuration, never touches Pi, Codex, or Cursor credentials, and reuses a verified existing broker instead of starting duplicates. - Verification and rollback: Verifies health endpoints, listener ownership, and Page Agent connectivity without sending a model turn, then reports binary path, mode, and remaining manual steps. - Use Case: A user asks to set up Page Agent on their Mac for a remote whiteboard; the agent installs the CLI if missing, trusts the exact HTTPS origin, starts a supervised foreground broker, and verifies the connection in the browser without sending a model message. ## Quick Start Ask your agent to set up Agent Whiteboard for your project, stating whether you need publishing only or Page Agent, and which server origin to use.
