claude-universe — Claude Code plugin: what it does, how to install
Adds five analytical layers to Claude Code to evaluate test depth, map code structure, and review PR readiness.
/plugin marketplace add anthropics/claude-plugins-community
/plugin install claude-universe@claude-communityWhat claude-universe does
The plugin organizes 20 commands under five functional pillars: Navigate, Diagnose, Shield, Survey, and Timewarp. Running /orbit triggers a repo sweep across test health and security posture. You can also inspect git diffs directly with /orbit pr. For focused investigations, dedicated agents assess threat models, trace data paths from ingress to persistence, and flag code drift.
Under the hood, five bundled MCP servers compute dependency graphs, churn metrics, and AST patterns without extra manual setup. Deterministic MCP analysis works strictly on JavaScript, TypeScript, and Python. For any other codebase, the tool steps down to manual inspection via Grep and Read without halting execution.
What it helps with
- evaluate PR readiness on git diffs before merging
- generate unit tests with deep assertion coverage
- model STRIDE threats and trace unvalidated inputs
- map architectural blast radius before applying changes
- spot coupling and drift across recent commit history
Example prompts for the agent
- Run a quick health check with /orbit quick
- Review security vulnerabilities in changed files with /security-review
- Trace feature data flow from input to storage using /trace
