Agent Skills
Give your coding agent practical guidance for building, testing, securing, upgrading, and operating Java applications with Mu Server. The skills are open, portable instruction sets that an agent loads when they are relevant to your task.
Quick install
From the project where you use Mu Server, run:
npx skills add 3redronin/mu-server-skills
The installer lets you choose the skills to add and the coding agent to use. It installs into the current
project by default, so the setup can be shared with the project. Add --global to make the skills
available across your projects instead.
Install for a specific tool
Use the matching agent name to go directly to the installer for your tool:
| Tool | Command |
|---|---|
| Codex | npx skills add 3redronin/mu-server-skills --agent codex |
| Claude Code | npx skills add 3redronin/mu-server-skills --agent claude-code |
| Cursor | npx skills add 3redronin/mu-server-skills --agent cursor |
| GitHub Copilot | npx skills add 3redronin/mu-server-skills --agent github-copilot |
| Gemini CLI | npx skills add 3redronin/mu-server-skills --agent gemini-cli |
| OpenCode | npx skills add 3redronin/mu-server-skills --agent opencode |
The skills installer supports many more coding agents. You can also give an agent with its own skills installer the Mu Server skills repository URL directly.
Choose the skills
List the available skills without installing anything:
npx skills add 3redronin/mu-server-skills --listInstall one skill, for example the getting-started guide:
npx skills add 3redronin/mu-server-skills \
--skill mu-server-get-startedOr install every skill globally:
npx skills add 3redronin/mu-server-skills \
--skill '*' --globalWhat the skills cover
The collection includes guidance for getting started, handlers, Jakarta REST, static resources, uploads, WebSockets, asynchronous streaming, Swagger, browser security, testing, production operation, ACME certificates, Murp reverse proxies, and version upgrades.
After installing, ask your agent naturally—for example, “Create a Maven application with Mu Server and a
/hello route,” or “Review this Mu Server service for production readiness.” The agent can select the
relevant skills automatically.
