Greenway Partners / Field System
A command-driven operating system for people who use Claude to produce work they're accountable for — not a prompt list, a working method.
Most people use AI like a vending machine — question in, answer out, and the quality of what comes back roughly matches the quality of the question. The Loop is sixteen mode-switching commands, organised into three editions, for turning Claude into an instrument you actually direct.

Field report
“The Practitioner's Playbook is a great tool for improving the way I work with Claude. The commands are practical, easy to understand, and help make responses more focused, clear, and useful. I especially love how it offers different modes for different tasks, from quick answers to deep reasoning. A valuable resource for anyone who wants to get more out of Claude!”
