What I'd show you first

Featured project

UI Pattern Library

Interface patterns lifted out of projects I actually shipped. Each one renders live in an isolated frame and comes with its markup, its styles, its behaviour, and the prompt that rebuilds it from scratch.

Patterns: 40
Categories: 5
Dependencies: 0

cc-dash

A dashboard and Model Context Protocol server for a project portfolio whose entire state lives in markdown files. Twenty-five zod-typed MCP tools let Claude Code read roadmaps, advance sessions, and work QA queues without anyone opening the UI. No database: the files are the source of truth, and git is the audit log.

MCP tools: 25
Tests: 1,667
