🟡list_packages
List every package with breaking-change data available, including tracked versions and how many breaking changes each has. Call this first if you are unsure whether a package is covered.

}🟢get_breaking_changes(package, version)
Get breaking changes for a package upgrade: removed APIs with their replacements and the reason for each, changed defaults, behavior changes, known incompatible dependencies, official source URL, and codemod/automated-fix commands. Omit `version` to get every tracked version. Use this instead of relying on training data, which may predate the release.

}🟢check_upgrade_safety(package, target_version)
Given a package and the version you are upgrading TO, return a concise checklist an agent can act on: the count of breaking changes, the highest-risk removals, whether automated codemods exist, and the recommended upgrade path. Use before performing an upgrade.
