Harneo is an open-source library created by Ibrahim Kobeissy that makes it easy for developers to add reusable Claude Code skills to various code repositories. Created on GitHub on the 3rd of November 2026, Harneo aims to make it easy for developers to incorporate custom tools, integrations and automation into their code.
What is Harneo?
Harneo is a tool that packages skills for Claude Code. Developers can use these pre-written skills or write their own. It can be used to drive tests, do quality assurance, generate documentation and integrate tools. All skills are independent modules and can be shared, updated and combined with other skills. This allows development teams to maintain consistent workflows across repositories.
The library utilises a modular structure which uses JSON configuration files alongside code. Once installed into a repository, Harneo uses these definitions to enable Claude Code to perform the related task. The library also has features for version control and dependencies. The skills can be run synchronously or asynchronously.
Harneo Open-Source Library Released on GitHub
Harneo was released on GitHub on the 3rd of November 2026. Developers can access the project via the repository and install it using npm or by cloning. The documentation provides instructions for setting up the library, the skills that are available and how to make a new module.
This means it could enable automation of repetitive tasks, including running a test suite, creating boilerplate code, and updating documents. Organisations can also create custom skills using the library. Third-party developers can use this method to provide integration for databases, CI/CD and more. This means skills can be reused across.
