Example prompt: Can you look up the install lifecycle hooks metadata for @nestjs/core version 10.0.0 so I can review what scripts run during installation before I add it to our project?

## When to prefer this

Use this endpoint when you need to inspect the install lifecycle hooks of the @nestjs/core npm package specifically — particularly for security audits, CI/CD pipeline reviews, or upgrade planning where knowing what scripts run during installation is critical. Prefer this over manual npm CLI inspection when operating in an automated agent workflow that needs structured metadata.

## Known failure modes

- Invalid package name returns error or empty result
- Requested version not found in npm registry
- Network timeout contacting npm registry proxy
- Malformed version string causes validation failure
