OpenClaw Integration Guide

This document explains how to configure OpenClaw CLI to connect to a SkillHub private registry for publishing, searching, and downloading skills.

Overview

SkillHub provides a ClawHub-compatible API layer, allowing OpenClaw CLI to seamlessly integrate with private registries. With simple configuration, you can:

• 🔍 Search for private skills within your organization
• 📥 Download and install skill packages
• 📤 Publish new skills to the private registry
• ⭐ Star and rate skills

Quick Start

1. Configure Registry URL

Set the SkillHub registry address in your OpenClaw configuration:

# Via environment variable
export CLAWHUB_REGISTRY_URL=https://skillhub.your-company.com

2. Authentication (Optional)

For global namespace (@global) PUBLIC skills, no login is required to download. Authentication is required for:

• Team namespace skills (regardless of visibility)
• NAMESPACE_ONLY or PRIVATE skills
• Write operations like publishing, starring, etc.

# Using API Token
export CLAWHUB_API_TOKEN=YOUR_API_TOKEN

Obtaining an API Token

1. Log in to SkillHub Web UI
2. Navigate to Settings → API Tokens
3. Click Create New Token
4. Set token name and permissions
5. Copy the generated token

3. Search Skills

# Search for skills
npx clawhub search email

# View skill details
npx clawhub info my-skill

4. Install Skills

# Install latest published version
npx clawhub install my-skill

# Install specific version
npx clawhub install my-skill@1.2.0

# Install skill from team namespace
npx clawhub install my-namespace--my-skill

5. Publish Skills

# Publish a skill (requires appropriate permissions)
npx clawhub publish ./my-skill

API Endpoints

SkillHub compatibility layer provides the following endpoints:

Endpoint	Method	Description	Auth Required
/api/v1/whoami	GET	Get current user info	Yes
/api/v1/search	GET	Search skills	Optional
/api/v1/resolve	GET	Resolve skill version	Optional
/api/v1/download/{slug}	GET	Download skill (redirect)	Optional*
/api/v1/download	GET	Download skill (query params)	Optional*
/api/v1/skills/{slug}	GET	Get skill details	Optional
/api/v1/skills/{slug}/star	POST	Star a skill	Yes
/api/v1/skills/{slug}/unstar	DELETE	Unstar a skill	Yes
/api/v1/publish	POST	Publish a skill	Yes

Notes:

• The compatibility layer may still expose the term "latest" externally, but it must strictly mean "latest published version"
• Internally, compat responses should map from the unified lifecycle projection's publishedVersion rather than inferring an ad hoc "current version"

* Download endpoint authentication requirements:

• Global namespace (@global) PUBLIC skills: No authentication required
• All team namespace skills: Authentication required
• NAMESPACE_ONLY and PRIVATE skills: Authentication required

Skill Visibility Levels

SkillHub supports three visibility levels with the following download permission rules:

PUBLIC

• ✅ Anyone can search and view
• ✅ Global namespace (@global): No login required to download
• 🔒 Team namespaces: Authentication required to download
• 📍 Suitable for organization-wide, publicly shareable skills

NAMESPACE_ONLY

• ✅ Namespace members can search and view
• 🔒 Login required and must be namespace member to download
• 📍 Suitable for team-internal skills

PRIVATE

• ✅ Only owner can view
• 🔒 Login required and must be owner to download
• 📍 Suitable for skills under personal development

Important Notes:

• Global namespace (@global) PUBLIC skills support anonymous downloads for wide distribution within the organization
• All team namespace skills (including PUBLIC) require authentication to ensure team boundary security

Canonical Slug Mapping

SkillHub internally uses @{namespace}/{skill} format, but the compatibility layer automatically converts to ClawHub-style canonical slugs:

SkillHub Internal	Canonical Slug	Description
@global/my-skill	my-skill	Global namespace skill
@my-team/my-skill	my-team--my-skill	Team namespace skill

OpenClaw CLI uses canonical slug format, and SkillHub handles the conversion automatically.

Configuration Examples

ClawHub CLI Environment Variables

ClawHub CLI is configured via environment variables:

# Registry configuration
export CLAWHUB_REGISTRY_URL=https://skillhub.your-company.com
export CLAWHUB_API_TOKEN=sk_your_api_token_here

Environment Variables

# Registry configuration
export CLAWHUB_REGISTRY_URL=https://skillhub.your-company.com
export CLAWHUB_API_TOKEN=sk_your_api_token_here

# Optional: Skip SSL verification (development only)
export CLAWHUB_SKIP_SSL_VERIFY=false

FAQ

Q: How do I switch back to public ClawHub?

# Unset custom registry
unset CLAWHUB_REGISTRY_URL

# ClawHub CLI will use the default public registry

Q: Getting 403 Forbidden when downloading?

Possible causes:

1. Skill belongs to a team namespace, authentication required
2. Skill is NAMESPACE_ONLY or PRIVATE, authentication required
3. You're not a member of the namespace
4. API Token has expired

Solution:

# Set new token
export CLAWHUB_API_TOKEN=YOUR_NEW_TOKEN

# Test connection
curl https://skillhub.your-company.com/api/v1/whoami \
  -H "Authorization: Bearer $CLAWHUB_API_TOKEN"

Tip: Global namespace (@global) PUBLIC skills can be downloaded anonymously without authentication.

Q: How do I see all skills I have access to?

# Search all skills (filtered by permissions)
npx clawhub search ""

Q: Permission denied when publishing?

• Publishing to global namespace (@global) requires SUPER_ADMIN permission
• Publishing to team namespace requires OWNER or ADMIN role in that namespace
• Contact your administrator for appropriate permissions

Q: Which OpenClaw versions are supported?

SkillHub compatibility layer is designed to work with tools using ClawHub CLI. ClawHub CLI is distributed via npm:

# Install ClawHub CLI
npm install -g clawhub

# Or use npx directly
npx clawhub install my-skill

If you encounter compatibility issues, please file an issue.

Security Recommendations

1. Use HTTPS: Always use HTTPS in production
2. Token Management:
   • Rotate API tokens regularly
   • Never hardcode tokens in code
   • Use environment variables or secret management tools
3. Least Privilege: Assign minimum required permissions to tokens
4. Audit Logs: Regularly review SkillHub audit logs

Troubleshooting

Enable Debug Logging

# View detailed request logs
DEBUG=clawhub:* npx clawhub search my-skill

# Or use verbose mode
npx clawhub --verbose install my-skill

Test Connection

# Test registry connection
curl https://skillhub.your-company.com/api/v1/whoami \
  -H "Authorization: Bearer YOUR_TOKEN"

# Test search
curl "https://skillhub.your-company.com/api/v1/search?q=test"
