About Claude Skills Marketplace
Claude Skills Marketplace is a curated collection of plugins (Skills and Agents) that extend Claude Code's capabilities for software engineering workflows. Skills are automatically triggered by Claude based on context, covering Git automation, code review, test fixing, feature planning, visual documentation (diagrams, flowcharts, timelines), productivity (code auditing, project bootstrapping), code operations (execution, refactoring, file analysis), and an execution runtime environment. The marketplace is open source and hosted on GitHub, allowing developers to install and customize plugins to streamline their development processes.
Key Features
Git automation skill for committing, pushing, and managing branches
Code review and test fixing skills integrated into workflow
Feature planning agent that helps design and implement new functionality

FAQ
What are Skills in Claude Skills Marketplace?
Skills are model-invoked capabilities that extend Claude Code's functionality. Unlike slash commands that require explicit user activation, Skills are automatically triggered by Claude based on context and the Skill's description. Each Skill consists of a SKILL.md file with YAML frontmatter, detailed instructions, and optional supporting files.
What are Agents in the marketplace?
Agents are specialized Claude instances that can be invoked by Claude to handle specific types of work. They run independently with their own context and can use different models optimized for their task.
How do I install a plugin from the marketplace?
The marketplace is hosted as a GitHub repository. You can clone or download the repository and follow the instructions in each plugin's README file for installation. Plugins are organized in directories such as engineering-workflow-plugin, visual-documentation-plugin, etc.
Is Claude Skills Marketplace free?
Yes, the marketplace itself is open source and free to use. However, using the plugins requires access to Claude Code, which is a separate paid service from Anthropic.
