gan-style-harness

gan-style-harness extends your AI assistant with the ability to head-to-head comparison of coding agents (Claude Code, Aider, Codex, etc.) on custom tasks with pass rate, cost, time, and consistency metrics. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using gan-style-harness as its underlying capability.

gan-style-harness integrates with Claude through the Model Context Protocol (MCP) standard. The skill is version-controlled and shareable — if you work with a team, you can commit the skill to your project repo and everyone gets the same capability without any extra setup.

gan-style-harness installs like any other MCP skill: drop the folder into `~/.claude/skills/gan-style-harness/` for global access, or `.claude/skills/gan-style-harness/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/gan-style-harness`, or let the AI decide when it's the right tool for your request.

gan-style-harness is a community-contributed AI productivity skill available through DiscoverAISkills. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
