<p align="center">Claude Code plugin that <strong>hard-blocks</strong> dependency additions, bumps, and downgrades until a fresh, source-cited version check is recorded.</p>

> If Claude tries to add `"lodash": "^4.17.21"` without looking up the latest version first, the tool call is rejected with exit 2. Claude must run `WebSearch`, then `/vs-record`, then retry. Five ecosystems supported in v0.1.

**Keywords:** Claude Code, Anthropic, AI coding guardrails, LLM supply-chain security, dependency management, hallucinated package versions, npm, PyPI, Cargo, NuGet, PreToolUse hook.
