SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Build, maintain, evaluate, and enforce the agent harness — skills, agents, hooks, CLAUDE.md, AGENTS.md, and enforcement infrastructure. Use when: "create a skill", "update skill", "improve the harness", "sync skills", "eval skill", "lint skill", "tune the harness", "add skill", "remove skill", "convert agent to skill", "audit skills", "skill health", "unused skills", "lint this skill", "eval this skill", "evaluate this skill", "validate this skill", "check this skill".

Core Features & Use Cases

  • Centralized governance for design, audit, and deployment of skills and harness components.
  • Clear routing of modes, references, and hooks to ensure consistent behavior across projects.
  • Cross-harness compatibility and scalable workflows for Claude Code, Codex, and Pi.

Quick Start

Run the setup to initialize the harness scaffolding and begin experimenting with skills and agents.

Frequently Asked Questions about harness

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit and lint agent skills across multiple projects?

To audit and lint agent skills across multiple projects, you enforce cross-harness discipline for hooks, CLAUDE.md, and AGENTS.md. This coordinates governance workflows to ensure consistent behavior and safe distribution across Claude Code, Codex, and Pi environments.

What is an agent harness and when do I need to enforce its governance?

An agent harness encompasses your skills, agents, hooks, and configuration files like CLAUDE.md. You need to enforce harness governance when building, evaluating, or syncing these components to maintain quality gates and ensure safe lifecycle distribution across projects.

How do I convert an agent into a reusable skill?

To convert an agent into a reusable skill, you route its modes, references, and hooks through centralized harness governance. This encodes design principles and lifecycle enforcement to ensure the resulting skill scales safely across different project environments.

Does cross-harness skill governance work with both Claude Code and Codex?

Cross-harness skill governance works with Claude Code, Codex, and Pi. It provides centralized routing of modes, references, and hooks to ensure scalable workflows and compatible behavior across these distinct platforms.

How do I check for unused or unhealthy skills in my agent harness?

You check for unused or unhealthy skills by running a harness audit to evaluate skill health and lifecycle state. This validates your skills against design principles and quality gates to identify components safe for removal or update.

What are the limitations of manually syncing skills without harness governance?

Manually syncing skills without harness governance risks inconsistent behavior and breaking quality gates across projects. Without centralized enforcement of lifecycle hooks and design principles, safe distribution across environments like Claude Code and Codex cannot be guaranteed.
