A developer grew tired of Jekyll, Hugo and Gatsby and built a blog from the ground up. Starting with raw HTML, he switched to JSON posts, then added a Markdown‑to‑HTML converter, and finally scripted compilation and deployment. He found the frameworks too restrictive for custom routing and asset pipelines. The resulting toolchain is a home‑grown static site generator—a textbook case of yak shaving.

The term was coined by MIT AI Lab graduate student Carlin Vieri after a bizarre Ren & Stimpy episode, and it has since become shorthand for chains of incidental work. Engineers often fall into the trap, but history shows approach can yield breakthroughs—Donald Knuth created TeX by writing his own language, compiler, font and line‑breaking algorithm. It forces developers to understand each layer, from I/O to rendering.

The lesson is practical: before discarding a mature tool, weigh the hidden cost of a custom stack. Yak shaving can teach low‑level fundamentals, but unchecked it wastes time and resources. Most developers should stop once the core requirement is met, reserving full rebuilds for cases where existing solutions truly fall short. Students often encounter yak‑shaving in assignments, gaining deeper insight into system design.
