Jwx V4
Add this marketplace so your agent follows lestrrat-go/jwx v4 patterns when parsing, signing, and validating JWTs and JWK material in Go services.
Overview
jwx-v4 is a plugin marketplace for the Build phase that adds jwx-dev-v4 agent guidance for Go apps using lestrrat-go/jwx v4 for JWT, JWS, JWE, and JWK tasks.
What is this marketplace?
- One-plugin jwx-v4 marketplace aimed at github.com/lestrrat-go/jwx v4
- Agent guidance for parse, sign, and verify JWTs with correct algorithm choices
- Coverage of JWS, JWE, and JWK workflows common in Go APIs
- Explicit focus on avoiding common jwx v4 footguns during implementation
- Fits Claude plugin flows for backend auth hardening alongside your repo
- 1 plugin in marketplace (jwx-dev-v4)
Community signal: 2.4k GitHub stars.
What problem does it solve?
Agents implementing Go auth often mishandle jwx v4 algorithms, key types, or verification steps and ship subtle token bugs.
Who is it for?
Indie Go API builders who want Claude-guided jwx v4 usage while implementing login, service JWTs, or JWK rotation.
Skip if: Frontend-only projects or teams standardized on a non-Go JWT stack with no jwx dependency.
What do I get? / Deliverables
After registration, your agent can apply v4-aligned patterns for signing, parsing, and key handling with fewer crypto footguns in your API.
- jwx-dev-v4 plugin available to agent sessions for token and key workflows
- Implementation-aligned answers for parse, sign, and algorithm selection in Go

Journey fit
Build is the primary journey phase because the plugin is a development guide for implementing auth crypto in Go backends, not a launch or growth tool. Backend subphase matches API services that issue sessions, verify tokens, and integrate JWS, JWE, and JWK without library footguns.
How it compares
Go JWT library dev plugin marketplace, not a hosted auth SaaS or generic brainstorming skill.
Common Questions / FAQ
Who is Jwx V4 for?
It is for Go backend developers and solo founders who use Claude agents while building services with github.com/lestrrat-go/jwx version 4.
When should I use Jwx V4?
Use it while implementing or refactoring JWT signing, verification, JWE, or JWK loading in Go before you ship auth-critical paths.
How do I add Jwx V4 to my agent?
Add the Jwx V4 marketplace in Claude Code and enable the jwx-dev-v4 plugin so agent sessions pick up the bundled development guide from ./agents/plugin.
