The awesome collection of Claude Skills with official and community-built resources.
Awesome Claude Skills
Claude Skills are folders with instructions, scripts, and resources that teach Claude specific tasks. Skills can include executable code and are loaded only when needed, allowing you to maintain hundreds without performance impact. Multiple skills can run together for complex tasks like document creation, code testing, and data analysis.
Note: Claude Skills have now become the Agent Skills standard adopted by multiple AI coding assistants. This means skills listed here can also be used with Codex, Gemini CLI, and other compatible tools. See the table below for paths and documentation.
What a Basic Skill Looks Like?
---
name: api-tester
description: Test REST APIs and validate responses
---
# API Tester
Test HTTP endpoints and validate response structures.
## When to Use This Skill
Use this skill when you need to test API endpoints and verify response data.
## Instructions
When testing an API:
1. Send a request to the specified endpoint
2. Check the response status code
3. Validate the response body structure
4. Report any errors or unexpected results
## Response Validation
- Verify required fields exist
- Check data types match expected values
- Confirm nested objects have correct structure
See the official repo and creation guide for more details.
