The advanced stuff the community actually swears by: how to pace your quota so it lasts the week, how to configure a workflow that doesn't fight you, how non-coders ship their first app. Every playbook is pulled from a high-signal discussion, labeled for what's verified fact and what's just one person's experience, and distilled into steps you can copy tomorrow.
Official rules live in the guides — this section is how the community actually plays the game.
