I build small tools constantly, mostly to solve my own problems: keeping track of what I'm doing, cutting steps out of repetitive work, making my setup less annoying to live in. Blackglass is where those tools go once they're good enough for someone else to use.

Try these things!

Glass

Obsidian Plugin

The actual Claude Code CLI, running inside Obsidian. Not a wrapper. Not a chat interface. Every slash command, every MCP tool, full session continuity, right alongside your notes.

  • Real terminal in your sidebar, powered by xterm.js
  • Built-in MCP server with structured vault access: read, search, write
  • Quick Ask modal for one-shot queries without a full session
  • Context menus on notes and selected text

Cadence

Claude Code Workspace

A markdown-based operating system for engineering managers, built on Claude Code. People files, program tracking, 1:1 recaps, meeting notes and promo tracking live as version-controlled markdown on your machine, and a set of slash commands turn that into your actual weekly rituals instead of a folder you never open.

  • Local-first: your org lives in plain markdown, not locked in a platform
  • Pairs with Obsidian and Glass to run sessions right alongside your notes
  • Slash commands for 1:1 prep, weekly reviews, upward status, and promo tracking
  • Optional Notion mirror if you want ritual output pushed somewhere shared

brewyeet

Homebrew CLI

brew update brew upgrade brew autoremove brew cleanup brew doctor. Or just run brewyeet and be done with it.

GitHub Template

Maybe the most delightfully nerdy thing I've ever built. A TypeScript template for building your own branded command-line calling card, the same one behind npx scottkosman. ASCII art welcome screen, a bio, and a menu of your own links. Generate your own copy, fill in your details, publish it as your own CLI.

  • Interactive ASCII-art welcome screen with your own bio and avatar
  • Quick-links menu that opens your sites and socials in the browser
  • One config file holds everything that makes it yours
  • Ships as a GitHub template: generate your own copy, fill in your details, npm publish
