A curated list of practical "Claude Skills," this repository provides customizable workflows to enhance productivity across Claude.ai, Claude Code, and the Claude API. It offers users a readily available set of tools to teach Claude how to perform specific, repeatable tasks, thereby standardizing and extending its capabilities for diverse applications without requiring deep technical expertise for each skill.

How It Works

Claude Skills are modular workflows packaged with instructions and metadata. Each skill is a self-contained folder, typically including a SKILL.md file detailing its purpose, usage, and instructions for Claude. This structure allows skills to be easily integrated and executed consistently across all Claude platforms, enabling Claude to interact with external tools and perform complex actions programmatically.

Quick Start & Requirements

• Claude.ai: Access skills via the skill icon (🧩) in the chat interface; add from the marketplace or upload custom skills.
• Claude Code: Place skill folders into ~/.config/claude-code/skills/. Start Claude Code via the claude command.
• API: Integrate skills programmatically using the anthropic Python library by specifying skill IDs in the messages.create call.
• Prerequisites: Access to Claude platforms and the anthropic Python SDK for API usage.

Highlighted Details

• Playwright Browser Automation: Enables model-invoked automation for testing and validating web applications.
• CSV Data Summarizer: Automatically analyzes CSV files, generating insights and visualizations without explicit user prompts.
• Slack GIF Creator: Produces animated GIFs optimized for Slack, including validators for size constraints.
• File Organizer: Intelligently organizes files and folders by understanding context, identifying duplicates, and suggesting structures.
• Threat Hunting with Sigma Rules: Leverages Sigma detection rules for threat hunting and security event analysis.

Maintenance & Community

Community resources include the official Anthropic Skills Repository for examples, a Claude Community for discussions, and a Skills Marketplace for discovery and sharing. Links to official documentation, user guides, and API details are provided.

Licensing & Compatibility

The repository is licensed under the Apache License 2.0. However, individual skills within the repository may carry different licenses, requiring users to check each skill's specific folder for licensing information. Apache 2.0 is generally permissive for commercial use.

Limitations & Caveats

The repository itself does not list specific limitations or alpha statuses. The primary caveat is that the quality, functionality, and licensing of individual skills can vary, necessitating user review before integration.
