About

Render assistant reasoning in a collapsible row. State-driven (thinking shimmer / thought static). Self-contained port from 21st.dev Agent Elements with React-only collapsible (no @base-ui/react) and inline shimmer keyframes.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Thinking Tool to your project and fits it to your theme.

Code

How Thinking Tool is used: the demo's code. The component's own source comes with a free account.
