1Harness Creatorharness-creator is a journey-wide agent skill for solo builders who want repositories that coding agents can start quickly, stay within scope, verify before claiming done, and resume after interruptions. It is not for picking models, tuning prompts in isolation, or general application architecture. The skill inspects what you already have—instruction files, feature state, test commands, manifests—then designs a lightweight harness around five subsystems: instructions, state, verification, scope, and lifecycle. You get concrete artifacts like AGENTS.md or CLAUDE.md, feature_list.json or progress.md, documented init.sh or check commands, and session-handoff routines. Use it at the start of a new repo, before a multi-session feature, or whenever agents overreach or forget context. The payoff is fewer half-finished PRs and restartable sessions without bloated rule dumps that agents ignore.648installs
