cobusgreyling/loop-engineering has accumulated 10,269 stars and 1,395 forks since its 2026-06-09 creation (roughly 163 stars/day) and was pushed again today, framing agent orchestration as a named practice inspired by Addy Osmani and Boris Cherny. It ships three CLI tools — loop-audit, loop-init, and loop-cost — that treat the prompt-orchestrate-evaluate cycle as an artifact to be measured rather than tuned by feel. The loop-cost tool is the practically interesting one: it puts a price on an agent loop before you run it at scale.
