+
+## Overview
+
+技能草稿创建管理。用于显式创建新 Skill draft，默认不向普通 Agent 暴露。
+
+## When to Use
+
+- Use when the task requires Skills Authoring Admin guidance.
+
+## Required Tools
+
+- `skill_manage`
+
+## 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 Authoring Admin — 技能草稿创建
 
 创建新的技能草稿。这个能力用于管理员、开发者或受控的技能创作流程，不属于默认初始 Agent 能力。

 - `content` (str): 技能正文（SKILL.md 格式）

-## 使用原则
+#### 使用原则
 
 1. 只有用户明确要求创建或沉淀一个 Skill 时才使用
 2. 创建草稿前确认 skill 名称、触发场景、工具依赖和正文边界
 3. 技能正文使用标准 frontmatter + Markdown 格式
 4. Draft 创建后必须经过 review → publish 流程才能生效
 5. 自学习候选生成草稿不依赖这个 tool；自学习流程走 SkillLearningPipelineService
+
+## 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.
