Claude Skills Marketplace
A marketplace of Claude Code plugins for engineering workflows: feature planning, tests, review, git automation and a code execution runtime
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- The runtime executes code
- Git automation changes repository history and branches
Install
Manual install
/plugin marketplace add mhattingpete/claude-skills-marketplaceYou can add a single plugin, e.g. /plugin marketplace add mhattingpete/claude-skills-marketplace/engineering-workflow-plugin.
This is third-party code. Review the repository files before installing.
What it does
Claude Skills Marketplace is a set of Claude Code plugins for development work. It includes an engineering-workflow plugin with skills for feature planning, ensemble problem solving, test fixing, review implementation and git automation, a code-operations plugin (execution, refactor, transfer, file operations) and visual-documentation and productivity plugins. It also ships a code execution runtime with an importable API library and a FastMCP server, installed in one command. Plugins install through its own marketplace and are invoked from Claude Code.
Who it is for. For developers who want ready-made Claude Code workflows for planning, tests and review.
Good fit when
- You need skills for feature planning and review implementation
- You need git automation and test fixing through an agent
- You need a code execution runtime for codebase operations
Not a fit when
- You need one narrow skill rather than a set of plugins
- Your agent is not Claude Code and does not support these plugins
Example request
Plan a feature from this description and prepare an implementation plan with acceptance criteriaLimitations
The plugins target Claude Code. The code execution runtime runs code and needs a separate install via setup.sh. The git automation skills change history and branches, so the result should be checked.
How to disable. Uninstall the plugins via /plugin uninstall and remove the added marketplace; remove the execution runtime separately.
Security check
- The runtime executes code
- Git automation changes repository history and branches
README in short
The README describes Claude Skills Marketplace as a set of Claude Code plugins for engineering workflows. Its structure holds the marketplace manifest, an engineering-workflow plugin with feature-planning, ensemble-solving, test-fixing, review and git-automation skills, a code-operations plugin and documentation and productivity plugins. It separately provides a code execution runtime with an API library and a FastMCP server installed in one command. Plugins are added via /plugin marketplace add, whole or by individual path.
FAQ
Can I install just one plugin?
Yes. You can add the marketplace of a specific plugin such as engineering-workflow-plugin and install only that.
What is the code execution runtime?
A separate component with an API library and a FastMCP server that runs code, installed via setup.sh.
