webview-cli

Show a native macOS webview UI to the user and get structured input back. Use when an interactive macOS session needs human-in-the-loop for multi-field input, option selection from 5+ choices, approval with context, or content review — NOT for yes/no questions. Handles the full flow — spawning the webview, generating A2UI or HTML content, parsing the user's response. Triggers on "show UI", "ask user", "approval needed with context", "let me pick from these options", "fill in these fields", or any situation where a structured GUI materially beats asking in the terminal. Skip in CI/non-interactive environments.
