7 GitHub Repositories to Improve Your Claude Code Workflow

Claude Code can work with a project out of the box, but you can extend its workflows with reusable skills, plugins, and other community-built tools. The challenge is finding resources that are genuinely useful for your work—and reviewing them before you install anything.

These seven repositories are good places to explore. They serve different purposes, from official skill examples to curated directories and development workflows.

1. anthropics/skills

Anthropic’s public skills repository is a useful starting point for understanding how skills are structured. It includes examples for tasks such as document creation and technical workflows, along with a template for creating your own.

Best for: Learning how skills are organized and building a custom skill.

2. obra/superpowers

Superpowers provides a structured development workflow built from composable skills. It emphasizes steps such as understanding the task, planning, testing, and reviewing work rather than jumping straight into code generation.

Best for: Developers who want a more guided, process-oriented coding workflow.

3. hesreallyhim/awesome-claude-code

This curated list collects tools and resources for Claude Code, including skills, plugins, integrations, and developer utilities. It can be a useful discovery page when you know what kind of capability you want but don’t yet know which project to try.

Best for: Browsing a broad selection of Claude Code resources.

4. ComposioHQ/awesome-claude-skills

This repository catalogs Claude skills and plugins across a range of use cases. Explore it when you’re looking for a specialized workflow or want ideas for how skills can support work beyond coding.

Best for: Finding skills by task or area of work.

5. alirezarezvani/claude-skills

This collection offers skills and plugins across areas such as engineering, product, marketing, and business. Its domain-based organization can make it easier to look for a bundle related to a particular kind of work.

Best for: Exploring a large, multi-purpose skills collection.

6. jqueryscript/awesome-claude-code

Another directory of Claude Code tools and resources, organized into categories such as agents, skills, plugins, integrations, and developer utilities. Comparing curated lists can surface projects that don’t appear in your usual searches.

Best for: Discovering additional tools and integrations.

7. obra/superpowers-marketplace

This marketplace collects Claude Code plugins for workflows, skills, and productivity. It can help users explore related extensions from one place, including plugins associated with the Superpowers workflow.

Best for: Finding plugins that can be installed through a marketplace workflow.

Review a repository before installing

A GitHub repository can change over time, so check its current documentation before following installation instructions. Review what permissions a plugin or skill needs, what scripts it runs, and whether it sends data to external services. Start with one extension in a low-risk project, then evaluate whether it improves your workflow.

The most useful setup is rarely the one with the most plugins. Choose tools that solve a real problem—such as repetitive setup, code review, or test planning—and keep the rest of your workflow simple.
