anthropic-skills

Overview

skills is Anthropic’s open-source repository of reusable agent skills—structured tool definitions, workflows, and example behaviors—for Claude-based systems, implemented primarily in Python with JSON/YAML schemas. It gives developers copy-pastable building blocks for common tasks such as browsing, file operations, and structured planning so they can assemble complex agents without reimplementing boilerplate. It is important because it standardizes best practices for tool design and error handling in Claude-centric agent stacks.
