Core Concepts
| 概念 | 说明 |
|---|---|
| Dynamic Skill | 按需安装的 skill，可清理 |
| Pinned Skill | 系统 skill，受保护不可删除 |
| Registry | skill 元数据存储 |
自动保护的系统 Skills：self-improving-agent, pahf, error-log-selfcheck, dynamic-skill-manager
Quick Start
# 同步已安装 skills 到注册表
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py sync
# 列出所有 skills（📌 = pinned）
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py list
# 查看系统 skills
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py pinned
# 查找闲置 skills（N 天未使用）
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py idle 30
# 安全卸载 skill（有输入验证）
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py uninstall <skill-name>
# 记录 skill 使用
python3 ~/.openclaw/workspace/skills/dynamic-skill-manager/scripts/skill_manager.py track <skill> "<context>"

Registry Schema
{
"skills": {
"skill-name": {
"installed_at": "2026-03-07T03:00:00Z",
"source": "clawhub",
"usage_count": 5,

}
Integration Points
- After skill use:
track_usage(skill_name, context_summary) - On user request:
list_skills(),find_idle_skills(days)
Security Features
The uninstall_skill() function includes multiple safety checks:
- Input Validation: Skill names must be alphanumeric with dashes/underscores only
- Path Traversal Prevention: Resolves paths and verifies containment within skills directory
- Symlink Detection: Rejects symlinks to prevent attacks
- System Skill Protection: Prevents accidental deletion of critical skills
