BuildAgent skills & templates

Harness engineering is a Build concern first because you assemble agent roles and orchestration before you rely on eval loops at ship time. agent-tooling is the canonical home for multi-agent role design, orchestration patterns, and Claude Code plugin harnesses.

How it compares

Multi-agent harness engineering plugin for Claude Code, not a curated skill pack or executive work-management bundle.
