# Vercel Validates every `skills-lock.json` written by the [Vercel skills CLI](https://github.com/vercel-labs/skills): strict JSON, the versioned project-lock shape, required source metadata, digest syntax, and paths that remain portable across machines. Lockfiles are discovered recursively for monorepos and the rule auto-enables when one is present. | Rule ID | Description | Default Severity | Autofix | |---------|-------------|------------------|---------| | [`skills-lock-valid`](skills-lock-valid.md) | skills-lock.json files must be valid and portable project lockfiles | error (auto) | - |
