Over the past months I built an entire AI workflow around our Unity codebase - a custom persona, a stack of skills, several agents, full multi-agent pipelines and then deleted most of it. What survived made me faster than all of it combined.

This is the story of that workflow: what it actually takes to go from writing every line yourself to directing the work, on a real Unity/C# production codebase at Starberry. The result isn't a magic robot that replaces you - it's a "party" of prompts, skills, and agents you assemble around your own needs, letting you ship like a bigger team and spend your judgment on what to build instead of grinding out every line of how.
No hype, no perfect demos - including the parts where I over-built it and had to cut back.
