Kiro CLI demo: building a Rust CLI tool

The terminal shows the Kiro CLI launching with an ASCII wordmark and a welcome message. It initializes with the claude-opus-4.6 model. The user types a slash command, revealing an autocomplete menu with options including /paste, /plan, and /prompts. The user then enters a detailed prompt asking to build a Rust CLI tool called crabbymark. The agent switches to plan mode (shown as '[plan] kiro_planner'), summarizes the request, and begins researching — displaying tool calls for listing files, searching the web, and fetching web content.
