Top ClawHub Skills for Developers
ClawHub is the central registry for OpenClaw skills — a community marketplace where developers discover and share capabilities for AI agents. This guide covers the top ClawHub skills worth installing, including persistent storage, automated deployment, testing, and more.
What is ClawHub?
ClawHub is the package registry for OpenClaw — think npm for AI agent capabilities. You install a "skill" with a single command and the agent gains the ability to interact with external APIs, databases, or file systems. No custom integration code.
The marketplace has hundreds of verified skills covering storage, deployment, testing, communication, and more. This guide covers the ones worth installing first.

Storage and File Persistence Skills
Without persistent storage, agents lose everything when a session ends or a container restarts. These skills give agents somewhere to actually keep files.
1. Fast.io (File Storage & RAG)
Fast.io gives agents a persistent file system that outlasts the session. Each agent gets its own cloud account with 50GB free and a full set of MCP tools for file operations. Files survive container restarts, are organized into workspaces, and can be shared with human collaborators.
Intelligence Mode auto-indexes uploaded documents for semantic search — no separate vector database needed. Agents can also pull files directly from Google Drive, Dropbox, or Box via URL import.
Best For: Agents that need to store and retrieve project files, share deliverables with humans, or read large documentation sets.
Install Command: clawhub install dbalve/fast-io

2. S3
A reference skill for working with S3-compatible object storage. Covers security, lifecycle policies, and access patterns across AWS S3, Cloudflare R2, Backblaze B2, and MinIO.
Key Features:
- Presigned URL generation with configurable expiration
- Lifecycle rules for tiered storage and auto-deletion
- Multipart upload guidance for large files
- CORS configuration for browser-based uploads
- Cost optimization strategies for request volume and egress
Best For: Teams working with any S3-compatible storage provider.

3. Filesystem Management
Advanced filesystem operations for agents that need to search, filter, and organize files on disk. Goes beyond basic read/write with filtering by type, size, and date.
Key Features:
- Recursive directory scanning with depth control
- Pattern matching via glob and regex for file search
- Full-text content search with context display
- Batch file copying with dry-run preview
- Tree visualization and space analysis
Best For: Local development, log analysis, and system administration tasks.

Add Persistent Storage to Your ClawHub Agent
Install the Fast.io skill to give your AI agent 50GB of free, persistent cloud storage and built-in RAG.
Communication & Web Skills
These skills let agents send emails, browse web pages, and post to Slack — the basic external communication operations that most agent workflows eventually need.
4. AgentMail
AgentMail gives your AI agent its own functional email address. Agents can send notifications, read incoming support tickets, and draft replies for human approval.
Key Features:
- Send/Receive capabilities
- Attachment handling
- Label organization
Best For: Customer support bots and notification systems.
Install Command: clawhub install agentmail/core
ClawHub Page: clawhub.ai/adboio/agentmail
5. AgentBrowser
AgentBrowser is a headless browser skill for navigating websites, filling out forms, taking screenshots, and extracting data. It handles dynamic JavaScript content that simple curl requests miss.
Key Features:
- Full DOM interaction
- Screenshot capture
- Session management
Best For: QA testing and web scraping workflows.
Install Command: clawhub install agent-browser/web

6. Slack
The Slack skill connects your agent to Slack workspaces, allowing it to post updates, reply to threads, and manage channels. It supports rich text formatting and interactive block kit elements.
Best For: Team notifications and ChatOps.

DevOps & Deployment Skills
Browser automation, Docker operations, GitHub management, and Google Workspace access — useful for agents that do more than write code.
7. Playwright
Browser automation through Playwright and its MCP integration. Agents can navigate pages, click elements, fill forms, capture screenshots and PDFs, and extract structured data from rendered pages. Includes test framework integration via @playwright/test, selector code generation, trace capture, and CI/CD patterns.
Best For: End-to-end testing, web scraping, and UI automation workflows.

8. Docker Essentials
A reference skill for Docker CLI operations. Covers container management, image building, Docker Compose orchestration, networking, volumes, and system cleanup. Includes practical workflows for development containers, database setups, and multi-stage builds.
Best For: Local development environments and containerized deployments.

9. GitHub
Enables agents to interact with GitHub through the gh CLI. Agents can manage pull requests, check CI status, view workflow run logs, query the GitHub API, and filter results with --jq. Requires the gh CLI to be installed and authenticated.
Best For: PR reviews, CI monitoring, and issue management from within agent workflows.

10. Gog (Google Workspace)
A CLI for Google Workspace that gives agents access to Gmail, Calendar, Drive, Contacts, Sheets, and Docs through terminal commands. Agents can search emails, read and update spreadsheets, create calendar events, and export documents. Requires OAuth setup with Google credentials.
Best For: Agents coordinating tasks across Google Workspace applications.

Coding & Testing Skills
SQL, structured coding workflows, security auditing, and multi-API access. Useful once your agent setup moves past basic code generation.
11. Code
A structured coding workflow that walks agents through planning, implementation, verification, and testing phases. It saves user coding preferences locally and includes bundled guides for each stage. Security-first design with no automatic code execution and explicit user approval between stages.
Best For: Developers who want structured, step-by-step guidance during coding sessions.

12. SQL Toolkit
A command-line reference for querying, designing schemas, running migrations, and optimizing SQLite, PostgreSQL, and MySQL databases. Covers joins, aggregations, window functions, CTEs, EXPLAIN analysis, and index strategies. Includes a zero-setup SQLite path for quick prototyping.
Best For: Backend optimization, schema design, and database debugging.

13. API Gateway
A unified interface to connect with over 100 third-party APIs through managed OAuth. Agents can call native endpoints for Google Workspace, Slack, Notion, HubSpot, Salesforce, Stripe, Airtable, and more without managing individual credentials.
Best For: Agents that interact with multiple SaaS APIs without custom auth code.

Five Skills Worth Installing First
If you're starting fresh, these five cover the gaps that come up most often:
- Fast.io — Persistent storage plus RAG. Free with 50GB.
- AgentMail — Email in and out. Free tier available.
- AgentBrowser — Headless browser. Usage-based.
- Playwright — E2E testing and browser automation. Free.
- Docker Essentials — Container management reference. Free.
Storage comes first because agents that can't save files can't build anything lasting. Email and browser come next because most workflows eventually need to reach out to something external.
Frequently Asked Questions
How do I install skills from ClawHub?
