✨ TL;DR

Best-practice orchestration for Harness Engineering on Claude Code — assembles the best open-source Claude Code ecosystem components, weaving them into a unified workflow via opinionated composition skills; does not vendor upstream code — manifests describe install/check, and composition skills orchestrate multi-upstream collaboration.

🔁 The operating loop

Discuss → Plan → Build → Verify → Ship, closed by a Learn loop — machine-executed across the three-layer stack (gstack governance · GSD orchestration · superpowers TDD · checkpoint evidence). Raw agent work drifts; harnessed turns it into a source-of-truth path where progress and evidence persist instead of living in chat. Learning is automatic: every completed workflow appends its failure/lo
