# Open Source Code

Projects, side hustles, experiments, and small open-source tools I built to solve my own problems. All open source, all live on GitHub (https://github.com/kleinmatic).

- **[NYC Schools Agentic](https://github.com/kleinmatic/nyc-schools-agentic)** · Journalism · AGPL-3.0
  A prototype interactive news application of NYC public-school data, serving both humans and their agents, using MCP and A2A.
- **[Open Journalism Bot](https://github.com/kleinmatic/open-journalism-bot)** · Journalism · MIT
  A Bluesky bot that watches for newly opened source repositories from news organizations and posts them to the feed.
- **[Claude Atlas](https://github.com/kleinmatic/atlas)** · AI · MIT
  A Claude Code plugin that keeps an AI-assisted codebase's docs from drifting — one home for every fact, plus “goodnight,” a clean end-of-session wrap-up. MIT-licensed.
- **[Claude Rooms](https://github.com/kleinmatic/claude-rooms)** · AI · GPL-2.0
  A filesystem message bus for coordinating multiple Claude Code agents. They join shared rooms and exchange messages as data — no daemon, no network service.
- **[LensFix](https://github.com/kleinmatic/lensfix)** · Hardware · GPL-2.0
  EXIF tools for photographers shooting vintage or manual lenses that don't talk to the camera body — command-line scripts plus a native macOS app for tagging a folder before import.
- **[Pi LED Control](https://github.com/kleinmatic/pi-led-control)** · Hardware · GPL-2.0
  A simple script for changing the status LEDs on single-board computers.
- **[Level One Diagnostic](https://github.com/kleinmatic/level-one-diagnostic)** · Hardware · GPL-2.0
  TUI that checks some basics to quickly test an SBC. Testing against some Raspberry Pi's and Radxa boards.
- **[BigLocalNews MCP](https://github.com/kleinmatic/biglocalnews-mcp)** · Journalism · AGPL-3.0
  An MCP server that wraps the Big Local News API, so an AI agent can search and pull from its data archive.
- **[Weeklypedia Feed](https://github.com/kleinmatic/weeklypedia-feed)** · Tool · GPL-2.0
  A self-updating RSS feed built from the Weeklypedia archive — the week's most-edited Wikipedia articles, as a feed you can subscribe to.
- **[domaininfo](https://github.com/kleinmatic/domaininfo)** · Tool · GPL-2.0
  A simple command-line tool for figuring out how and where a website is hosted.
