Free · Open · Operator-built
AI tools I build with, open for you to take.
Free, operator-built Claude Code skills and open-source projects, the same ones I rely on inside my own work. No signup. Fork them, adapt them, ship them. If one saves you a meeting, send it to a friend who needs it more.

Second Brain
Give your AI a long-term memory, built for people who talk more than they type. One prompt turns Claude Code plus a plain-text vault into a voice-first, self-organizing second brain; it files, links, and recalls so you don't have to.
Inside my own vault
Real numbers from the vault in the demo above: fully cross-linked, self-organized, recalled by voice.
Callable skills for Claude Code & Codex.
Download, drop into your skills folder, and invoke in plain language. Each one is a framework I actually use, packaged so it argues back instead of agreeing.
Playing to Win
Pressure-test a business idea, offer, or product through Roger Martin and A.G. Lafley's choice cascade. 12-section output, a Proceed / Narrow / Park / Kill verdict, and zero fake encouragement.
Voice Profile Builder
Build a voice profile from your pre-AI writing so AI drafts in your real voice, not generic AI prose. Point it at your old posts and essays; get a reusable profile that survives every future draft.
See what Claude Code is actually doing.
Local-first visibility into your own usage: which skills earn their place in context, and where the tokens and dollars actually go. Everything runs on your machine; nothing is uploaded.
Skill Usage Dashboard
Every enabled skill taxes your context window every session, used or not. It reads your local transcripts, shows real usage counts and token cost per skill, and gives each one a Keep / Modernize / Turn off / Prune verdict. Runs entirely on your machine; nothing is uploaded.
Claude Code Cockpit
Local-first token and cost visibility. A zero-dependency cc-usage CLI prints spend sliced by session, agent, skill, MCP server, or model, plus a one-command live Grafana dashboard with Max Plan Leverage and burn-rate panels that update as you build.
Field guide · Free · Operator-built
Loops are what come after prompts.
The library of repeatable agent loops I actually run. Start with the field guide: what a loop is, the seven parts every good one has, and when one earns its keep. Then copy the 43.
AI agent loops, explained
What a loop is, the seven parts every good one has, and where to copy 43 you can run for coding and non-coding work.
Inside the library
Each loop names its use case, cadence, the verification that proves it worked, and a prompt you can paste into a capable agent.

Field Notes is where I write up what's working inside operating businesses, the AI fixes I'm testing, and the lessons I'd give a friend. Free, occasional, no pitches.
