Simon Willison: Superpowers — How I'm using coding agents in October 2025

“Jesse is one of the most creative users of coding agents (Claude Code in particular) that I know. He's put a great amount of work into evolving an effective process for working with them, encourage red/green TDD (watch the test fail first), planning steps, self-updating memory notes and even implementing a feelings journal.”

Simon highlights Jesse Vincent's Superpowers plugin and the accompanying blog post, calling it a wildly creative set of customizations for Claude Code.
