Harness-build-skill

Bootstrap a reusable agent-first Harness for a monorepo from a filled `HARNESS_PROFILE.md`. Use when a team has documented project purpose, repo map, workflows, boundaries, and quality priorities and wants Codex/Pi to generate the Harness structure, docs, plans system, and stable operating files around those facts.

Bootstrap and adapt an agent-first Harness repository with reusable templates, repo-local docs, validation rules, active plans, and cleanup loops. Use when Codex needs to create a new Harness from scratch, turn an existing project into a legible agent-first workspace, or scaffold a software, research, or general-purpose repository that agents can navigate reliably.
