Cli

A month ago, I wrote about my first three weeks with Claude Code. At that point, I had a few tools working: an email CLI, a Tana integration, some calendar automation. It felt like a lot. I just ran the numbers. It’s considerably more than I thought. The Numbers Here’s what Claude and I have built together since early December: Project Files Lines of Code Supertag CLI (Tana) 163 44,116 Tool for my Psychotherapist wife 63 21,331 Email Skill 46 10,523 Daily Briefing - 4,481 PII Anonymizer - 2,894 Calendar (ical) - 2,235 Tado Thermostat - 1,551 Other KAI Skills 294 total ~70,000 Total: roughly 135,000 lines of TypeScript. ...

The core insight of PAI is deceptively simple: apply the Unix philosophy to AI. Small tools that do one thing well. Composable. Each tool you build makes the whole system more capable. Daniel built the meta-layer - the skill system, the delegation patterns, the constitutional principles that keep Claude focused and effective. I get to build on top of that foundation. ...

While my day job is managing a team of 8 engineers (which means a lot of meetings), I do get to work with the CLI from time to time.
