A browser-based editor for changing the styles and content of real HTML pages visually, then saving those changes as structured data for an agent to apply to source code.

Use it to edit HTML page appearance and content, record the edits, and apply them back to the project files.

It gives developers a direct way to adjust a page visually when describing every design change in text is slow or unclear.

page-editor — Skill for Claude Code and Codex by HK-hub

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add HK-hub/AgentSkills --skill page-editor

Clone the repo

git clone --depth 1 https://github.com/HK-hub/AgentSkills

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00154	$0.05241
Opus 5	$0.00077	$0.02620
Sonnet 5	$0.00031	$0.01048
Haiku 4.5	$0.00015	$0.00524

Measured 9d ago against content hash 8db33ae7d296, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

page-editor scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 27 executable files (assets/page-editor/bin/page-editor.js, assets/page-editor/public/editor/js/color-picker-engine.js, assets/page-editor/public/editor/js/color-picker-panel.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 377 lines — stays where its author put it; the contents beside it link to each section on GitHub.

页面可视化编辑器

基于浏览器的 HTML 页面可视编辑器。用户在浏览器中完成样式/内容编辑，保存后输出结构化 JSON，供 Agent 回写到源码。

⚠️ 项目隔离（重要）

本工具支持两种使用方式，强烈推荐方式 1：

方式 1：作为项目 Skill 使用（✅ 推荐）

将 page-editor/ 目录复制到你的项目 .codebuddy/skills/ 目录下：

cp -r {skill-base-dir} {your-project}/.codebuddy/skills/page-editor/

优势：

✅ 完全项目隔离，多个项目互不影响
✅ 端口文件 .page-editor.port 和输出文件 page-edits.json 存储在项目目录
✅ 可以为不同项目定制 Skill 配置
✅ 版本管理更清晰（每个项目独立管理 Skill 版本）

方式 2：作为全局 Skill 使用（⚠️ 需注意）

如果作为全局 Skill 使用（安装在 ~/.codebuddy/skills/），需注意：

端口文件隔离：v2.3.4+ 已支持项目隔离，.page-editor.port 会存储在目标文件所在目录
输出文件：page-edits.json 默认输出到当前工作目录，建议通过 --output 参数显式指定项目目录
多个项目同时编辑：确保每个项目使用不同的 --port，避免端口冲突

示例（全局 Skill 多项目使用）：

# 项目 A
cd /path/to/project-a
node ~/.codebuddy/skills/page-editor/assets/page-editor/bin/page-editor.js --file ./index.html --output ./page-edits.json &

# 项目 B（使用不同端口）
cd /path/to/project-b
node ~/.codebuddy/skills/page-editor/assets/page-editor/bin/page-editor.js --file ./index.html --port 7789 --output ./page-edits.json &

修改记录存储位置

文件	存储位置	说明
`.page-editor.port`	目标文件所在目录（v2.3.4+）或 CWD	记录编辑器服务端口号
`page-edits.json`	`--output` 参数指定（默认 `./page-edits.json`）	保存时的改动记录
浏览器 localStorage	用户浏览器	编辑状态临时存储（仅当前会话）

快速开始（双进程模型）

本工具采用 双进程架构，必须严格按以下顺序启动：

# ===== 第 0 步：安装依赖（仅需首次，后续跳过）=====
SKILL_DIR="{skill-base-dir}/assets/page-editor"
if [ ! -d "$SKILL_DIR/node_modules" ]; then
  cd "$SKILL_DIR" && npm install --prefer-offline --no-audit --no-fund
fi

# ===== 第 1 步：启动服务进程（后台常驻，只启动一次！）=====
# 日志写入临时文件以便排障；服务就绪后会自动打开浏览器（延迟 4s，页面显示加载遮罩直到 JS 就绪）
LOGFILE="/tmp/page-editor-$(date +%s).log"
nohup node {skill-base-dir}/assets/page-editor/bin/page-editor.js --file <目标HTML路径> > "$LOGFILE" 2>&1 &
SERVICE_PID=$!

# ===== 第 1.5 步：等待服务就绪（重要！不要跳过）=====
for i in $(seq 1 30); do
  if [ -f ".page-editor.port" ]; then break; fi
  sleep 0.5
done
if [ ! -f ".page-editor.port" ]; then
  echo "⚠️ 服务未能在 15 秒内启动，请检查日志: cat $LOGFILE"
fi

# ===== 第 2 步：启动监听进程（前台阻塞，10 分钟超时）=====
# 阻塞等待用户保存或关闭编辑器。10 分钟内无操作会超时退出。
node {skill-base-dir}/assets/page-editor/bin/page-editor.js --monitor

What ships with it

40 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
