cdx — Claude Developer Experience

Setup wizard and code review tools for Claude Code projects. Eliminates repetitive project bootstrapping by auto-detecting tech stacks, configuring LSP plugins, generating simplifier agents, and setting up duplication detection.

Install

claude plugin install cdx@deviantony-plugins

Commands

/cdx:setup

Interactive wizard that walks you through:

1. Tech stack detection — scans for go.mod, package.json, Cargo.toml, pyproject.toml, etc.
2. Git initialization — sets up git repo and .gitignore if needed
3. LSP plugin installation — installs Claude Code LSP plugins for your detected languages
4. Simplifier agent generation — creates tailored code simplification agents in .claude/agents/
5. jscpd setup — configures duplication detection for your tech stack

/cdx:review

Code review workflow that:

1. Identifies recently changed files (committed, staged, and unstaged)
2. Runs your project's simplifier agent(s) against changed files
3. Runs jscpd duplication detection
4. Presents combined results with actionable next steps

Supported Languages

Go, Python, TypeScript, JavaScript, Rust, Java, Ruby, C#, PHP, Swift, Kotlin, C/C++, Lua, Elixir
