Claude Agent Skills

Claude Agent Skills

Repository for Anthropic Claude Skills examples demonstrating how to use Claude's Skills API with both **default skills** (document generation) and **custom skills** (extensible functionality).

Overview

This project provides two categories of examples:

Default Anthropic Skills (Document Generation)

Python examples for using Anthropic's built-in Skills API to programmatically generate various document types:

• 📊 Excel (xlsx) - Spreadsheets, data tables, charts
• 📽️ PowerPoint (pptx) - Presentations, slides
• 📄 PDF - Documents, forms, reports
• 📝 Word (docx) - Documents, letters, proposals

Custom Skills Framework

A flexible framework for creating and running your own custom skills:

• 🔧 Extensible Architecture - Create custom skills with simple markdown instructions
• 🤖 Intelligent Selection - Claude automatically chooses the right skill for the task
• 🔍 Git Analyzer - Example custom skill for analyzing Git repositories
• 🛠️ Tool Integration - Uses bash tool execution for maximum flexibility

Prerequisites

Required

1. **Anthropic API Key** (required for all examples)

   • Visit console.anthropic.com
   • Create an account or log in
   • Navigate to "API Keys" section
   • Generate a new API key
   • Ensure your account has access to Skills beta features
   • Note: This is separate from Claude Code/Cline subscriptions

2. **Python 3.7+**

Important Note About Claude Code Pro

Having a Claude Code Pro subscription does **NOT** provide access to the Anthropic Skills API. These are separate services:

• Claude Code Pro = VS Code extension subscription (interactive development)
• Anthropic API Key = Programmatic API access (separate service, separate billing)

You need an Anthropic API key to run the code in this repository, regardless of your Claude Code subscription.
