jwx
Complete implementation of JWx (Javascript Object Signing and Encryption/JOSE) technologies for Go. #golang #jwt #jws #jwk #jwe
The jwx Claude Code plugin is a developer assistant skill that provides guidance for using the lestrrat-go/jwx Go library, a comprehensive implementation of JOSE (JavaScript Object Signing and Encryption) standards. The plugin helps developers navigate JWT, JWS, JWE, and JWK operations by recommending algorithms, demonstrating parsing and signing patterns, and highlighting common pitfalls. It is scoped specifically to version 4 of the jwx library and designed for developers integrating JOSE technologies into their Go applications, not for contributors working on the library itself.

What is the jwx-dev-v4 Claude Code plugin?+
It is an AI assistant skill bundled with the lestrrat-go/jwx library that helps developers use the library's JOSE (JWT/JWS/JWE/JWK) functionality. The plugin provides interactive guidance on algorithm selection, signing/verification patterns, and common security pitfalls when working with version 4 of the jwx Go module.
How do I install the jwx-dev-v4 plugin in Claude Code?+
Use the command '/plugin marketplace add lestrrat-go/jwx' to add the repository, then '/plugin install jwx-dev-v4' to activate the skill. The plugin will then be available to assist with jwx library development tasks.
Which AI clients support this plugin?+
This plugin is specifically designed for Claude Code, which is Claude's AI-powered development environment. It is not compatible with other AI clients or assistants.
Do I need API keys or prerequisites to use this plugin?+
You need access to Claude Code and the jwx v4 Go library installed in your project (via 'go get github.com/lestrrat-go/jwx/v4'). On Go 1.26, you must also set GOEXPERIMENT=jsonv2; Go 1.27+ includes this by default.
Is the jwx-dev-v4 plugin free to use?+
Yes, the plugin is open source and bundled with the MIT-licensed jwx library. However, you need Claude Code access, which may have its own pricing or availability requirements.
Can this plugin help with contributing to the jwx library itself?+
No, the jwx-dev-v4 skill is scoped exclusively for developers using the library in their applications. It is not intended to assist with internal library development or contributions to the jwx codebase.
