donchitos publishes skills that help an AI agent with game development work, including scoping small design changes, drafting player-facing patch notes from git history, building sprint plans from milestone progress, and reviewing UX specs and performance profiles against budgets. The catalogue also covers closing out finished stories against their acceptance criteria, configuring engine versions, and performing architectural code reviews.
