• Reliability: Active maintenance and verified real ClawHub pages.
• Ease of use: Simple install commands and minimal config.
• Integration: Works with common tools like VS Code, GitHub, Docker, and databases.
• Community: Skills with published pages on ClawHub with clear documentation.

Most skills are free and open-source. Installation is straightforward via ClawHub CLI or package managers.

Helpful references: Fast.io Workspaces, Fast.io Collaboration, and Fast.io AI.

The Code skill provides a disciplined coding workflow covering planning, implementation, verification, and testing for clean software development. Instead of generating code in one unstructured shot, the agent follows a documented process: break down the task, execute in steps, then verify correctness before completing.

Key strengths:

• Structured planning and execution flow for consistent output quality.
• Stores your coding preferences in ~/code/memory.md upon request.
• Includes reference files for task breakdown, execution, and verification steps.
• Works entirely within your ~/code/ directory and project files.

Limitations:

• Never executes code automatically; the agent plans and writes, you run.
• Instruction-only skill; no binaries to install.

Best For: Engineers who want consistent, methodical code generation with a clear audit trail of decisions.

Install Command: Download from ClawHub (instruction-only, no binary install required).

The GitHub skill uses the gh CLI to manage pull requests, check CI status, inspect failed workflow steps, and run advanced API queries. Your agent can open PRs, read issue threads, check run outputs, and query repository data with --json and --jq filters, all from a chat session.

Key strengths:

• Full PR lifecycle: create, review, merge, and check CI status.
• Advanced API queries with JSON output and jq filtering for precise data extraction.
• Inspect failed CI steps to diagnose build failures without leaving the conversation.

Limitations:

• Requires gh CLI pre-installed and authenticated via gh auth login or GITHUB_TOKEN.
• Instruction-only skill; no separate binary.

Best For: Teams doing frequent PRs and CI pipeline work who want their agent to handle GitHub operations natively.

Install Command: Instruction-only; run gh auth login or set GITHUB_TOKEN.

Playwright provides browser automation via MCP. Your agent can navigate websites, click elements, fill forms, take screenshots, export PDFs, and extract structured data from JavaScript-rendered pages, without writing separate test scripts.

Key strengths:

• Real browser automation for pages that require JavaScript rendering.
• Screenshot and PDF capture for visual regression testing.
• Multi-step form completion and UI debugging from a chat session.
• Structured data extraction from rendered pages.

Limitations:

• Runs headless by default; headed mode requires display configuration.
• Browser instances consume memory during long automation sessions.

Best For: Frontend engineers who want agentic end-to-end testing and scraping without writing Playwright scripts manually.

Install Command: npx @playwright/mcp --headless

Add Persistent Storage to Your OpenClaw Dev Workflow

Pair OpenClaw skills with Fast.io workspaces for persistent file storage and collaboration. Free agent tier: 50GB storage, 5,000 credits/month, no credit card required.

Storage for Agents

The SQL Toolkit lets agents query, design, migrate, and optimize SQL databases. It supports SQLite, PostgreSQL, and MySQL. Your agent can write complex joins, aggregations, window functions, and CTEs, as well as build migration scripts and run EXPLAIN analysis. SQLite works with zero setup, making it ideal for rapid local development.

Key strengths:

• Handles design, querying, migration, optimization, backup, and restore across the same skill.
• Complex query writing including window functions, CTEs, and multi-table joins.
• Query optimization with indexes and EXPLAIN analysis.
• SQLite for no-setup local data exploration.

Limitations:

• Requires sqlite3, psql, or mysql CLI tools to be installed.
• Instruction-only skill; agents write queries but you execute them.

Best For: Backend engineers who need their agent to work fluently across multiple database environments.

Install Command: Download from ClawHub (requires sqlite3, psql, or mysql CLI).

Docker Essentials covers container operations from basic lifecycle commands through multi-stage image builds and Docker Compose orchestration for multi-container applications, including networking, volume management, and system cleanup.

Key strengths:

• Container lifecycle management: run, stop, restart, inspect, and debug.
• Multi-stage build patterns for keeping production image sizes small.
• Docker Compose for orchestrating frontend, backend, and database containers locally.
• Common workflow examples included for development and database setups.

Limitations:

• Requires Docker CLI to be installed on the system.
• Instruction-only skill; agents generate commands, you run them.

Best For: Developers containerizing full stack applications for consistent local and production environments.

Install Command: Download from ClawHub (requires Docker CLI installed).

Filesystem Management provides advanced file operations: smart listing with recursive traversal and pattern filtering, powerful content search, batch copy and move with dry-run mode, and directory tree visualization with statistics.

Key strengths:

• Content search across large directory trees for finding specific code or config patterns.
• Batch operations with dry-run mode to safely preview changes before execution.
• Directory analysis with statistics for auditing project structure.
• Pattern matching and recursive traversal for precise file targeting.

Limitations:

• Operates on local filesystem only.
• Requires execution permissions on the target directories.

Best For: Engineers working on large codebases who need fast, safe batch file operations from natural language.

Install Command: clawhub install filesystem

Fast.io provides 19 MCP tools for agent workspaces: file storage, sharing, document analysis, task management, approval workflows, and RAG-based document querying. Agents share files, index codebases for search, and hand off work to human reviewers through the same workspace, without switching tools or losing context between sessions.

Key strengths:

• 19 built-in MCP tools for comprehensive file and workspace management.
• Zero-config RAG: agents query uploaded files and codebases using natural language.
• Free agent tier: 50GB storage, 5,000 credits/month, no credit card required.
• Human-agent collaboration with ownership transfer and approval workflows.

Limitations:

• Requires a Fast.io account for the agent to connect.
• File-focused; pairs best with other skills that handle code execution or API calls.

Best For: Multi-agent projects where shared codebases and persistent file context are essential.

Install Command: clawhub install dbalve/fast-io

Start with 2-3 skills that match your immediate workflow. For most software engineers, the Code skill and GitHub skill together cover the majority of daily agent tasks. Add Playwright for frontend work or SQL Toolkit for backend database work as needed.

Test each skill in a sandbox OpenClaw instance first. Combine skills for complete workflows: use the Code skill for structured implementation, GitHub for PR submission, and Fast.io for sharing context between sessions or agents.

For file-heavy projects, pair Fast.io with Filesystem Management: use Filesystem Management for local operations and Fast.io for persistent cloud storage and cross-agent sharing.
