Behind The Badge: How We Built 2,000 Hackable Badges For Temporal Replay
The documentation from all the architecture debates I had with the AI, the back-and-forth about structure, what to build, and what to cut, is over 21,000 lines, managed through GitHub Spec Kit that tracked specs and architecture decisions as the project evolved. That ratio says something interesting about what the job actually looks like now. It was very out of my comfort zone as someone with a CS degree and a full career without any AI tools even existing. As this project took four months, I swapped my tooling quite a bit. I finalized the project leveraging Codex with the Grill Me Skill. It was a lot more reminiscent of wordsmithing an English essay than anything hands-on-keyboard, which I'm still adjusting to.

Haskell Foundation 2026 Update
I am using https://github.com/github/spec-kit and am pretty content. I also tell it in the constitution.md to generate the .fsi files first, then write tests for it before implementation. That might very well be useless superstition since it is soo easy to fool yourself.

Agent Skills
What makes this better/different than spec-kit? It seems to have a very similar philosophy. I wonder if they could work together? Or would they just be duplicative?
