Can I add my own custom rules?

Yes, write a new skill in markdown and encode the key points as additional checks inside the linter.

Will this work inside Xcode?

The skills load in any Claude Code session, but you must run the linter from a terminal because Xcode has no native hook support.

What is Joannis/claude-skills?

Joannis/claude-skills provides a set of expert Swift server skills stored as markdown files plus a dedicated swift-server-lint binary. The skills capture recurring best practices while the linter turns those practices into hard checks that run without relying on the model context.

A feedback loop encourages developers to review generated code, document improvements, add them as skills, and finally encode them as lint rules. Post-build hooks then block further progress until issues are resolved, keeping generated Swift server code consistent over time.

The project targets Swift developers who use Claude Code for server-side work and want to reduce repeated mistakes without constant manual prompting.

What you can build with Joannis/claude-skills

Maintain consistent server patterns

Store recurring Swift server decisions in skills so Claude follows the same conventions across multiple sessions and projects.

Catch issues after builds

Run the linter automatically via hooks so any deviation from documented rules is flagged before code is committed.

Onboard new team members

Share the skills directory so both humans and Claude start from the same set of Swift server guidelines.
