-# stylekit-style-prompts
+# @anxforever/stylekit-style-prompts-skill
 
-Standalone skill for generating high-quality frontend prompts from StyleKit styles.
+StyleKit 风格提示词 Skill（独立仓库版）。  
+目标：把 StyleKit 的风格能力直接安装到 Codex / Claude 的 skills 目录中。
 
-## Quick start
+## 1) 一键安装（面向使用者）
+
+### 安装到 Codex
+
+```bash
+npx @anxforever/stylekit-style-prompts-skill install --tool codex
+```
+
+### 安装到 Claude
+
+```bash
+npx @anxforever/stylekit-style-prompts-skill install --tool claude
+```
+
+### 自动检测本机工具并安装
+
+```bash
+npx @anxforever/stylekit-style-prompts-skill install --tool auto
+```
+
+### 覆盖安装（已存在时）
+
+```bash
+npx @anxforever/stylekit-style-prompts-skill install --tool codex --force
+```
+
+### 卸载
+
+```bash
+npx @anxforever/stylekit-style-prompts-skill uninstall --tool codex
+npx @anxforever/stylekit-style-prompts-skill uninstall --tool claude
+```
+
+### 环境自检
 
 ```bash
+npx @anxforever/stylekit-style-prompts-skill doctor
+```
+
+## 2) 本地开发验证（维护者）
+
+```bash
+node bin/stylekit-style-prompts-skill.js doctor
+node bin/stylekit-style-prompts-skill.js install --tool codex --target /tmp/stylekit-skill-test --force
+node bin/stylekit-style-prompts-skill.js uninstall --target /tmp/stylekit-skill-test
 python3 scripts/smoke_test.py
 python3 scripts/run_pipeline.py --query "高端科技SaaS财务后台，玻璃质感，强调可读性" --stack nextjs --format json
 ```
 
-## Regression gate
+## 3) 回归门禁
 
 ```bash
 bash scripts/ci_regression_gate.sh --baseline references/benchmark-baseline.json --snapshot-out tmp/benchmark-ci-latest.json
 ```
+
+## 4) 发布到 npm（让所有人可用）
+
+```bash
+npm login
+npm whoami
+npm publish --access public
+```
+
+发布后，任何人都可以通过 `npx @anxforever/stylekit-style-prompts-skill ...` 直接安装。
