Boost Your Ai
Add lightweight Java code intelligence inside Claude Code without installing a full JVM-based language server.
Overview
boost-your-ai is a plugin marketplace for the Build phase that adds a JVM-free Java language server (jj-language-server) to Claude Code.
What is this marketplace?
- Single plugin jj-lsp (v0.1.0) with jj-language-server over stdio
- Maps .java files to Java without requiring a JVM on the host
- 10s startup timeout and extensionToLanguage wiring for Claude Code
- Strict mode disabled for easier local installs from the repo
- Maintained by Arnaud Héritier under the boost-your-ai marketplace (v0.0.1)
- 1 plugin in marketplace (jj-lsp v0.1.0)
- Marketplace version 0.0.1
- LSP startup timeout 10000 ms
Community signal: 9 GitHub stars.
What problem does it solve?
Agent-assisted Java edits feel blind when Claude Code has no language server and you do not want to install a full JVM toolchain just for light intelligence.
Who is it for?
Solo builders using Claude Code who occasionally edit Java and want stdio LSP wiring without a heavyweight local JVM setup.
Skip if: Teams that already run IntelliJ or a full JDK language server stack and only need generic agent prompts, not another LSP plugin.
What do I get? / Deliverables
After adding the marketplace, .java files get LSP-backed structure and navigation hooks so agents and you can refactor and explore Java code with less guesswork.
- jj-lsp plugin registered on the boost-your-ai marketplace
- jj-language-server LSP session for .java in Claude Code
- Extension-to-language mapping for Java in the agent editor
Plugins in this marketplace
1 plugin — install individually after you add the marketplace.
Recommended Marketplaces
Journey fit
The marketplace ships an LSP plugin for in-editor Java support while you implement backend or JVM-era code with an AI coding agent. jj-lsp registers jj-language-server on Claude Code—classic agent-tooling that augments the coding environment rather than shipping app features.
How it compares
Claude Code LSP plugin bundle, not a reusable agent skill or MCP integration catalog.
Common Questions / FAQ
Who is Boost Your Ai for?
It is for Claude Code users who work on Java files and want jj-language-server code intelligence without requiring a JVM for the server itself.
When should I use Boost Your Ai?
Use it during Build when you are implementing or refactoring Java and need in-agent navigation and language-aware edits instead of plain-text guessing.
How do I add Boost Your Ai to my agent?
Register the marketplace from the Anthropic Claude Code marketplace flow, install the jj-lsp plugin, ensure jj-language-server is on PATH, then open .java files in Claude Code.
