harness skillA
harness is agent-read markdown (skill) from akillness/jeo-skills: Design domain-specific agent teams, define specialized agents, and generate the skills they use. Use when you need to decompose a complex project into coordinated multi-agent teams, choose the right architecture pattern (pipeline, fan-out/fan-in, expert pool, producer-reviewer, supervisor, hierarchical delegation), generate .claude/agents/ and .claude/skills/ files, or validate and iterate on generated harnesses. Triggers on: harness, build a harness, design agent team, agent team architecture, .
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# harness - Agent Team & Skill Architect
> **Keyword**: `harness` · `build a harness` · `design agent team` · `harness engineering`
>
> Meta-skill: harness designs the teams and skills that run your domain work.
Harness decomposes complex tasks into coordinated teams of specialized agents. It analyzes your domain, selects the right architecture pattern, generates agent definition files and skills, then validates the harness end-to-end.
**Agent Teams require**: `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
## When to use this skill
- Decompose a complex project into a coordinated multi-agent team
- Choose the right architecture: pipeline, fan-out/fan-in, expert pool, producer-reviewer, supervisor, or hierarchical delegation
- Generate `.claude/agents/{name}.md` agent definition files
- Generate `.claude/skills/{name}/SKILL.md` skill files with bundled resources
- Validate trigger conditions, dry-run teams, and compare with/without harness quality
- Build harnesses for: research, coding, content creation, code review, data pipelines, marketing

How to install
mdr add akillness/jeo-skills/harness@v1.0mdr add akillness/jeo-skills/harness@sha256:cd6403e7fcb134caPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
