Playbooks

Tactical guides for building with AI

Free, step-by-step guides to the unglamorous side of the work: keeping the bill down, running open models, sending each task to the model that earns it. Tools and prices age fast, so every playbook shows the date it was last verified.

Each guide also has an interactive version on melwyn Class, with animated terminal demos and Claude Code walkthroughs.
