Core Concepts

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,
      "last_used": "2026-03-07T03:00:00Z",
      "context_keywords": ["keyword1"],
      "pinned": false
    }
  }
}

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:

1. Input Validation: Skill names must be alphanumeric with dashes/underscores only
2. Path Traversal Prevention: Resolves paths and verifies containment within skills directory
3. Symlink Detection: Rejects symlinks to prevent attacks
4. System Skill Protection: Prevents accidental deletion of critical skills
