npm-supply-chain-check
Detect known malicious npm package versions and install-time supply-chain indicators in repositories, lockfiles, and node_modules. Use when a user mentions an npm compromise, Shai-Hulud, the Keyv/cacheable incident, suspicious preinstall scripts, credential-stealing packages, or asks whether a JavaScript project was exposed to a package supply-chain attack. Do not use as a general CVE or license audit.

# NPM Supply Chain Check
Run an evidence-bounded, read-only scan. Distinguish a dependency reference from
proof that malicious code executed, and never read or print secret values.
## Workflow
### 1. Fix the scan boundary
Resolve the exact repository or directory first. Default to the current
repository only. Do not silently expand a repo scan to the user's home directory,
all worktrees, global package caches, or CI systems.
### 2. Check intelligence freshness
