craft

what /craft/ is

the /craft/ pillar is for engineers who write code every day and want the muscle memory of the people who appear faster than everyone else on the team — not because they type faster, but because their tools fit their hand and their feedback loop is seconds, not minutes. we cover what the craft actually is in 2026: typescript types as documentation, the editor (vim, emacs, and increasingly claude code) as a force multiplier, debugging as a discipline with named techniques, and refactoring with tests as a safety net.

how the lessons work

the courses here are short, specific, and reproducible. each lesson teaches one technique with a runnable example you can edit in the browser, and a "rebuild from memory" exercise to check that the idea actually stuck. the writing index below complements the courses with one-problem-per-post articles — no intros, no conclusions, just the answer to the specific thing that broke.

what makes this different

ai-assisted coding tools have not replaced craft; they have raised the floor on the basics and put a much higher premium on the engineer who can read, evaluate, and shape what the machine produces. the courses here are written from that position: claude code, copilot, and cursor are assumed parts of the workflow, not novelties. the throughline is taste under pressure — the ability to recognize the right shape of code when the model offers four wrong ones first.
