Testing AI-Written Code
FoxFit has hundreds of tests, all passing, and the AI writes most of them. Here's our testing strategy and the session cleanup workflow that keeps quality high.

The Code Review System
AI-written code needs review. We created a review prompt library organised into phases, each examining a specific aspect of the codebase.

Building the Exercise Database
FoxFit needed an exercise library. We started with 914 exercises, curated it down to 150, and generated muscle-highlighted thumbnails for each one.

PRDs and Sub-Agent Teams
Every feature gets two documents: a PRD defining what to build, and an implementation prompt defining how, complete with team roles the AI adopts.

Claude Code has no memory between sessions. We solved this with a single file that carries architecture decisions, coding patterns, and rules across every conversation.
