ACP Thinking Spinner

To show a working indicator during LLM API calls in an ACP server, you can integrate a skill that synthesizes virtual tool calls with 'kind="think"' to display 'Thinking...' spinner cards in the client's tool-call stack.

Yes, thinking spinner cards work with various ACP client tools including Zed Agent Panel, openCode TUI, and JetBrains or VS Code ACP UI environments, providing a visual indicator while processing LLM API calls.

The best way to visually indicate ongoing processing for Agent Client Protocol LLM calls is synthesizing virtual tool calls to generate spinner cards, allowing users to confirm an active call without waiting for final results.

You add a thinking indicator to your agent configuration by integrating the acp-thinking-spinner skill, which automatically generates 'Thinking...' spinner cards whenever LLM calls are initiated on your ACP server.

No external dependencies are required to display spinner cards in the tool-call stack of ACP clients, as the skill operates using scripts to synthesize virtual tool calls for the working indicator.
