myharness

myharness — The Agent-Team Architecture Factory

English | 한국어 | 日本語

myharness is a Claude Code · Codex dual-runtime factory that turns a single sentence about your domain into an agent team and skills. Just say "Build a harness for this project" — it analyzes your domain and stamps out specialized agent definitions (.claude/agents/) and skills (.claude/skills/), picking whichever of the 6 team architecture patterns fits.

What is myharness?

When you tackle a complex job with one giant prompt, context gets polluted, the same blind spots repeat, and nothing is reusable. myharness decomposes that job and generates it as a team of specialized agents with separated roles + skills that carry the procedures + an orchestrator that weaves them together.

• Input: a single sentence about your domain (e.g., "deep research", "full-stack web development", "code review")
• Output: agent definitions + skills + an orchestrator skill + entry pointers (CLAUDE.md/AGENTS.md)
• Characteristics: Korean-first · slim by default (gates tighten only as risk rises) · outputs for both Claude Code and Codex

myharness itself is a meta skill (plugin), and it treats itself as a system that evolves — it feeds execution feedback back into the appropriate layer (skill/agent/orchestrator) and leaves a change history.

Quick Start

1. Install (pick one)

Marketplace (recommended)

/plugin marketplace add cookyman74/my_harness
/plugin install myharness@myharness-marketplace

Copy directly as a global skill

cp -r skills/myharness ~/.claude/skills/myharness

Codex CLI (dual runtime) — from the repo root:

bash install.sh
# → ~/.codex/skills/myharness  (symlink to the source of truth, always up to date)
# → .agents/skills/myharness   (for trusted projects)
# → AGENTS.md                  (auto-loaded by Codex)

2. Turn on agent teams + start the CLI (Claude Code)

export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
claude   # start the Claude Code CLI (for Codex, use the codex command)

3. Triggers

• Claude Code: Build a harness for this project · /myharness · Design an agent team for this domain
• Codex: $myharness · the /skills menu · Build a harness (description matching). A session restart after install is recommended. (Codex doesn't support custom slash commands — /myharness is unavailable.)
