Overview

A failed tool call in plain words: the error code, a collapsible stack, Retry and Edit arguments with JSON validation. It comes from the Tool calls kit and also works on its own. Keyboard and screen readers: The card is a section named by the error title; the code is text, not only a red color. Built with React 19 and TypeScript, Tailwind CSS 4, Lucide icons and Motion. Light and dark themes come from CSS variables you can edit, and every demo uses believable sample data you replace with your own. Included: the component source, its sample data, light and dark theme variables, a runnable demo page, and setup guides for people and for AI coding agents.
