This repository offers a curated marketplace of Claude Code plugins, extending its capabilities for software engineering workflows. It provides pre-built "Skills" and "Agents" that automate tasks like Git operations, testing, code review, documentation generation, and code manipulation. The primary benefit is streamlining complex development processes, significantly reducing manual effort and improving efficiency within the Claude Code environment.

How It Works

The core concept revolves around Skills (model-invoked capabilities triggered by context) and Agents (specialized Claude instances). A novel "Execution Runtime" is introduced, implementing Anthropic's code execution pattern. This allows Claude to execute Python code locally rather than loading it via context, achieving substantial token savings (90-99%) and enabling faster, stateful, and more secure bulk operations. Skills and Agents can orchestrate tasks, with Agents leveraging Skills for specific actions.

Quick Start & Requirements

Installation is straightforward via the Claude Code plugin manager: /plugin marketplace add mhattingpete/claude-skills-marketplace. This installs the entire plugin suite. Individual plugins can be installed using specific paths (e.g., /plugin marketplace add mhattingpete/claude-skills-marketplace/engineering-workflow-plugin). The Execution Runtime requires a one-command setup using setup.sh. Setup time is estimated at 2 minutes. No specific hardware prerequisites beyond the Claude Code environment are detailed.

Highlighted Details

• Execution Runtime: Offers significant token savings (90-99%), faster execution, stateful workflows, and sandboxed execution for bulk operations (10+ files) or complex multi-step tasks.
• Plugin Categories: Includes dedicated plugins for Engineering Workflow, Visual Documentation, Productivity Skills, and Code Operations, each containing multiple specialized skills.
• Agents: Features the plan-implementer agent, optimized with the Haiku model for efficient execution of planned tasks.
• Key Skills: Notable skills include git-pushing, test-fixing, review-implementing, code-execution, architecture-diagram-creator, codebase-documenter, and code-auditor.

Maintenance & Community

Contributions are welcomed via forking the repository, adding new skills following the provided structure and best practices, and submitting pull requests. Support and questions can be directed through GitHub issues. Community discussions are also mentioned as a resource.

Licensing & Compatibility

The project is licensed under the Apache 2.0 license. This license is generally permissive, allowing for commercial use and integration within closed-source projects.

Limitations & Caveats

The Execution Runtime and several skills are marked as "NEW!", indicating they are under active development and may be subject to change or contain undiscovered issues. The effectiveness of generalized skills may require adaptation for highly specific or niche development workflows. The functionality is entirely dependent on the Claude Code environment.
