Example prompt: Can you fetch the install lifecycle hooks for the yup npm package, version 1.3.3, so I can see what scripts it runs during installation?

## When to prefer this

Use this endpoint when you need to programmatically inspect the install lifecycle hooks of the yup npm package without manually querying the npm registry, particularly useful for automated security audits, dependency onboarding checks, or CI/CD upgrade planning pipelines.

## Known failure modes

- Invalid or non-existent package version returns an error or empty hook data
- Package name override pointing to a non-existent npm package returns a 404-style error
