一分钟后开始

1. 打开上方链接（Chrome / Edge）
2. 点击** 📁 选择文件夹** →选择你的项目根目录（包含.claude/的目录）
3. 点击左侧树中的任意.md文件→开始编辑

所有数据都保存在你自己的机器上。没有任何数据上传到服务器（由浏览器文件系统访问API驱动）。

为什么？

用Claude代码构建代理和技能很容易，但打磨它们——调整前置内容、细化描述、比较文件间表格——在通用编辑器中会变得笨拙。这是一个专注于这一任务的小工具。

特色

• 目录树视图，带有颜色编码的代理/技能/编排器，以及脏污和错误标记
• 前置信息表单编辑器 — 分别输入 name / description / type / model
• Markdown 正文编辑器 + 带同步分段滚动的分割预览

Harness Editor

English | 한국어

A single-page HTML tool for visually viewing and editing .claude/agents/*.md and .claude/skills/**/SKILL.md files used by Claude Code.

🌐 Try it now: https://amazingsyp.github.io/harness-editor/harness-editor.html (Chrome / Edge recommended)

Get started in 1 minute

1. Open the link above (Chrome / Edge)
2. Click 📁 Select folder → choose your project root (the directory that contains .claude/)
3. Click any .md file in the left tree → start editing

All data stays on your own machine. Nothing is uploaded to a server (powered by the browser File System Access API).

Why?

Building agents and skills with Claude Code is easy, but polishing them — tweaking the frontmatter, refining descriptions, comparing tables across files — gets awkward in a generic editor. This is a small tool focused on that one job.

Features

• Directory tree view with color-coded agents / skills / orchestrators, plus dirty and error markers
• Frontmatter form editor — separate inputs for name / description / type / model
• Markdown body editor + split preview with synced section scrolling
• WYSIWYG mode — edit tables, headings, and emphasis directly in the right pane
• Multi-file search and bulk replace (regex, target filters)
• Description-quality scoring (length, trigger phrases, follow-up keywords) aligned with the revfactory/harness meta-skill recommendations
• Roundtrip-safe serialization — parse → edit → save preserves meaning exactly
• Dark / light themes, page-close protection

Browser support

Inspiration

This tool is designed to work well with the file format produced by the revfactory/harness meta-skill — but it works with any standard Claude Code agent or skill .md file.
