Impeccable is a design vocabulary and automated visual quality control system built for AI coding agents including Claude Code, Cursor, Codex CLI, GitHub Copilot, Grok Build, and Hermes Agent. Designed for software engineers seeking to eliminate generic interface patterns, the platform provides twenty-four specialized commands categorized into steering, reviewing, finishing, live iteration, and project planning. Its live browser mode, launched via `/impeccable live`, enables developers to select UI elements, preview dynamic style variants directly on local development servers, and write approved updates back to project source code. Visual quality is enforced using a deterministic detector consisting of sixty-two rules that identify defects such as cramped padding, skipped headings, nested cards, and gray text on colored backgrounds without requiring large language model inference.
The GitHub snapshot shows the repository is not archived and records an Apache-2.0 license. The core execution engine operates as a self-contained binary, requiring Node.js solely for running the `npx` setup tool. Standard installation executes from the project root using `npx impeccable install`, followed by workspace initialization via `/impeccable init` or `$impeccable init` in Codex environments. On Hermes Agent, integrating the automated design hook requires executing `hermes plugins enable impeccable-design-hook`. The system also supports CLI-based directory scanning through `npx impeccable detect src/` and manual file installation across individual agent directories without Node.js.
