A modular, security-first universal developer toolkit for Claude Code — that detects what is really installed and never pretends to support tools that are absent.
Inside Claude Code (desktop, CLI or web), run:
/plugin marketplace add kaazyxx/ultimate-dev-toolkit
/plugin install ultimate-dev-toolkitThen run /udt:doctor to see exactly which tools and skills are live in your environment.
Auto-loading expertise across 70+ languages, every major framework, databases, DevOps, security, data/ML, AI/LLM, game & graphics, web3, embedded and more.
Namespaced, ready-to-run workflows: /git:*, /db:*, /security:*, /qa:*, /ai:*, /k8s:*, and dozens more.
Per-language reviewers, build-resolvers and auditors — security, performance, data-quality, LLM guardrails, resilience and beyond.
Advisory, never-block-by-default guards for destructive commands and secret writes, plus an audit trail and SessionStart auto-update.
sequential-thinking · memory · filesystem · blender — wired in through the plugin manifest.
Never claims a tool is supported unless it is actually detected. Real, functional entries over fake ones.
Full reference lives in the repository: Installation · Skills · Commands · Agents · Security.
