What is a Harness?

A Harness is a workflow package composed of 4-5 specialized AI agents and an orchestrator skill. It leverages Claude Code's agent team feature so you can apply it to everyday tasks instantly.

How to Use

Run Claude Code in the project folder where you installed the harness. Type a prompt that matches the skill's trigger conditions, and agents will run automatically.

Run the claude command in your project folder
Type a trigger prompt (e.g., "plan a YouTube video")

💡 Check trigger conditions and execution modes on each harness's detail page.

Execution Modes

Each harness offers multiple execution modes. You can run the full pipeline or choose a focused mode for a specific task.

›"full production" → Full Pipeline mode (runs all agents)

›"write a script only" → Script mode (runs a subset of agents)

›"review this script" → Review mode (runs reviewer agent only)

File Structure After Installation

After installation, a .claude/ folder is created in your project root.

my-project/
└── .claude/
    ├── agents/        # agent-name.md × 4-5
    ├── skills/        # skill-name/skill.md
    └── CLAUDE.md

•.claude/agents/ — Markdown files with agent roles and instructions
•.claude/skills/ — Skill files that orchestrate agent execution order
•.claude/CLAUDE.md — Harness metadata and project configuration

💡 You can directly edit agent files to customize roles, instructions, and output formats.

Troubleshooting

Skill is not recognized

Restart Claude Code. Type /exit in the terminal and run claude again.

How do I verify the installation?

Check that .claude/agents/ and .claude/skills/ folders exist in your project root.

I want to modify agent behavior

Edit the markdown files in .claude/agents/ directly. Changes take effect on the next run.

Existing files are kept and only new files are added (merge mode). If a file with the same name exists, you'll be asked to confirm overwriting.

Can I install multiple harnesses in one project?

Yes, add them to favorites and use [Setup All Favorites →] to install them all at once.

Do I need to log in?

No. All features are available without login, sign-up, or payment.
