Skill Installer

Install OpenClaw skills from clawhub.ai ZIP files with automatic detection, validation, and Gateway updates.

Features

• Automatic Detection: Finds OpenClaw installation location automatically
• File Search: Search for ZIP files in current directory when filename is not specified
• Duplicate Check: Verifies if a skill is already installed before proceeding
• Interactive Selection: Prompts user to choose when multiple matching files are found
• Validation: Validates skill structure (SKILL.md, _meta.json)
• Gateway Update: Automatically restarts Gateway to make new skills available
• Progress Feedback: Detailed status messages throughout the installation process

Usage

Basic Installation

# Install from a specific ZIP file
python3 scripts/skill_install.py my-skill.zip

# Search for ZIP files in current directory
python3 scripts/skill_install.py

# List all installed skills
python3 scripts/skill_install.py --list

# Show help
python3 scripts/skill_install.py --help

Workflow

1. File Detection:
• If filename is provided: Use that file directly
• If no filename: Search for *.zip files in current directory
• If multiple files found: Display list and ask user to choose

1. Validation:
• Check if OpenClaw is installed
• Validate ZIP file structure
• Verify SKILL.md and _meta.json exist

1. Duplicate Check:
• Extract skill name from SKILL.md
• Check if skill already exists in skills directory
• Prompt for confirmation if duplicate found

1. Installation:
• Extract ZIP file to skills directory
• Verify extracted files
• Restart OpenClaw Gateway

1. Completion:
• Display success message
• Show skill path
• Confirm Gateway restart

File Structure

The script expects skills to have the following structure:

skill-name.zip
├── SKILL.md          # Required: Skill metadata and documentation
├── _meta.json        # Required: Additional metadata
├── scripts/          # Optional: Python/Node scripts
│   └── *.py/*.mjs
├── references/       # Optional: Reference documentation
└── README.md         # Optional: Extended documentation

Requirements

• Python 3.6 or higher
• OpenClaw installed (via npm or nvm)
• Sufficient permissions to write to OpenClaw skills directory

Error Handling

Common Errors

Error: ❌ 未找到 OpenClaw 安装位置

• Solution: Install OpenClaw first using npm install -g openclaw

Error: ❌ ZIP 文件不存在

• Solution: Check the filename and path

Error: ❌ ZIP 文件不包含 SKILL.md

• Solution: Ensure the ZIP file is a valid skill from clawhub.ai

Error: ⚠️ Skill 已存在

• Solution: Confirm if you want to overwrite or use a different skill

Error: ❌ Gateway 重启失败

• Solution: Manually restart Gateway using openclaw daemon restart

Advanced Usage

Custom OpenClaw Path

If the script cannot find OpenClaw automatically, you can modify the OPENCLAW_PATH variable in the script:

OPENCLAW_PATH = "/custom/path/to/openclaw"

Skip Gateway Restart

To restart Gateway manually, comment out the restart call:

# restart_gateway(openclaw_root)

Troubleshooting

Permission Denied

If you encounter permission errors:

# Fix permissions
chmod 755 ~/.nvm/versions/node/*/lib/node_modules/openclaw/skills

Skill Not Appearing in OpenClaw

After installation, if the skill doesn't appear:

1. Restart Gateway manually:

```bash

openclaw daemon restart

```

1. Check OpenClaw logs:

```bash

openclaw logs --follow

```

1. Verify skill structure:

```bash

ls -la ~/.nvm/versions/node/*/lib/node_modules/openclaw/skills/your-skill/

```
