Create and Optimize AI Harnesses with Claude Code Agent Skills

This skill facilitates the design, generation, validation, and maintenance of a comprehensive Claude Code harness, including files such as CLAUDE.md, rules, skills, hooks, permissions, agents, and workflows. It is used to create or set up these components for a project, improve or extend an existing setup, or configure Claude to work with a specific codebase.

What this skill does

  • Starts with a phase of auditing by executing a script to inventory existing components and scout the codebase.
  • Conducts structured interviews to translate goals into specific component specifications.
  • Generates the required harness components based on the specifications derived from the interviews.
  • Performs mechanical validation of the generated components.
  • Offers end-to-end testing to ensure functionality and compliance with the specifications.
  • Ensures completion and readiness only when validated by the `validate_harness.py` script.

Who it is for

This skill is intended for developers and development teams using AI coding agents such as Claude Code, Cursor, and Codex. It is especially beneficial for those looking to create, optimize, or maintain AI agent harnesses for project-specific applications.

Use cases

  • Creating a structured AI harness for a new software development project.
  • Enhancing and extending an existing .claude/ setup to accommodate evolving project needs.
  • Configuring Claude to effectively interact with and improve a specific codebase.
  • Responding to Korean-speaking developers looking to setup or refine their AI harness, with support for requests like "하네스 만들어줘", "하네스 구성해줘", "클로드 세팅해줘".

Technical details

The skill employs several specialised tools and methodologies, including:

  • Python scripts for auditing and validation processes.
  • Utilization of harness-spec.md for detailed specification documentation.
  • Integration with Claude Code through the use of agent skills and workflows.

Ran it on a client's Google Ads account and it flagged wasted spend we'd been missing for months. Paid for itself on day one.

We finally caught broken conversion tags before launch instead of after. The pre-launch checklist alone is worth the price.

Dropped it into Claude Code and my LCP went from 4.1s to 1.9s in an afternoon. It explains every fix it suggests, so I actually learned something too.
