-# Skills Admin — 技能查看
+# Skills Admin
+
+## Overview
+
+技能（Skill）列表查看和内容加载。用于浏览已发布技能、读取技能正文和支持文件。
+
+## When to Use
+
+- Use when the task requires Skills Admin guidance.
+
+## Required Tools
+
+- `skills_list`
+- `skill_view`
+
+## Workflow
+
+- Identify whether the user's request matches the skill's trigger conditions.
+- Read the relevant source guidance below and apply only the steps that fit the current task.
+- Use the required tools deliberately and keep tool output tied to the user's goal.
+
+### Source Guidance
+
+### Skills Admin — 技能查看
 
 查看已发布的技能列表并加载技能详情。
 
-## 工具说明
+#### 工具说明
 
-### skills_list
+##### skills_list
 列出系统中所有可用技能及其描述。
 - 返回技能名称、描述和版本
 - 用于浏览当前可用的技能
 
-### skill_view
+##### skill_view
 加载某个技能的完整正文或支持文件。
 - `name` (str): 技能名称
 - `file_path` (str | None): 可选的支持文件路径
 - 不传文件路径时返回 SKILL.md 主内容
 - 支持按需加载 references/、templates/ 等目录
 
-## 使用原则
+#### 使用原则
 
 1. 需要参考某个技能的详细内容时，先 `skills_list` 找到名称，再用 `skill_view` 加载
 2. 用户问“你有哪些技能”时，优先使用 `skills_list` 获取当前可见技能
 3. 用户问某个技能如何工作时，用 `skill_view` 读取正文或支持文件
 4. 这个默认技能不创建草稿；技能创作能力属于单独的 authoring/admin skill
+
+## Validation
+
+- Verify the requested outcome with the most direct available check.
+- Report any skipped step, unavailable dependency, or remaining uncertainty explicitly.
+
+## Boundaries
+
+- Do not broaden the task beyond the user's request.
+- Do not use tools that are not listed or clearly available in the current runtime.
+
+## Anti-Patterns
+
+- Do not summarize the skill instead of applying it.
+- Do not claim completion without validation evidence.
