Edition 10.7 · Jun 18, 2026The builder's eval, one altitude above Chapter 25. Chapter 25 was a three-line smoke detector for a skill's artifact; Chapter 47 is for when the model's output is the product itself. The Anthropic API course ships, as working code, the two tools most builders never build — a way to SCORE output and a way to RETRIEVE the right context. Both ported to TypeScript over a weekend: a PromptEvaluator (synthetic dataset → cheap code-grade + LLM-judge → honest scorecard) and a hybrid BM25+vector retriever. The point isn't the 400 lines; it's that you can stop charging for AI output you can't score.
Edition 10.6 · Jun 16, 2026New showcase — /good-taste: stop your AI from generating generic slop. A before/after of Leon Lin's public taste-skill (45k★, credited), with the receipts I built using it.
Edition 10.5 · Jun 16, 2026The design reading. Forty-five chapters taught you to build with AI; none taught you to make it look like something. Chapter 46 fills the gap with the book's own receipts — a contrast failure that sat in our light-theme tokens for weeks until the arithmetic caught what every eye had passed, flicked.email's three landing pages in three different typefaces, and a moon-base image set for Reach art-directed with a public taste skill. Generation went to zero; selection didn't.
Edition 10.4 · Jun 16, 2026The fourth reading — the tier list gains an independent referee. Between the crowd's LMArena votes and the vendors' launch decks, Artificial Analysis runs its own agentic harness and prices every run, so you can finally sort the leaderboard by what a task actually costs, not just by who scores highest.
Edition 10.3 · Jun 11, 2026The economics week — the research timeline gets the grid that turns "this plan can't be profitable on me" into numbers, and the tier list catches up to the Fable 5 era with a fresh LMArena snapshot and a new lab-claims panel.

“It has always given me satisfaction to be able to create what I have in mind.”

The thesis
HTML-ization. Stop sending dead files.
Every deliverable — report, pitch, audit, deck, model — ships as a live interactive HTML artifact on a deployed link, not a PDF attachment that started rotting the second it was exported. The link is current because the repo is. People forward links; they archive PDFs unread.
This page is the proof. The book about building this kind of artifact is, itself, this kind of artifact — and the source you're holding is the recipe.
single-file HTML · ~114 KB · client / domains / infra de-identified
A real Folderly-methodology audit of a ~90-domain / ~5K-mailbox cold-email estate — swarmed in days, delivered as a clickable doc instead of a 40-page PDF.
If you scrolled this far, you might be the kind of person who'd appreciate the side project I'm not technically supposed to be working on yet.
An Autonomous Fighting Championship. Humanoid robots, an octagon, blacklight and bass, no humans bleed. The kind of idea you say out loud at dinner and watch the table decide if you're serious. I have a pitch deck. It exists because the deck got built before the next meeting did.
