Check for Breaking Changes Before Upgrading
Pull current documentation to understand what changed in a new library version before upgrading.
Quick answer: Use the Library Docs tool through ToolRouter to check for breaking changes before upgrading directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolUpgrading a major dependency without checking the changelog is how production breakages happen. The API may have changed, a method may have been renamed, or a default behaviour may have been altered in a way that only surfaces at runtime. Reading through changelogs and migration guides manually takes time that most engineers skip under deadline pressure.
The resolve_library and get_docs skills fetch current documentation for any package, including changelogs, migration guides, and version-specific API references. You can ask about what changed between two versions, what the migration path looks like, and which parts of your existing code are affected.
Engineers planning major version upgrades, teams maintaining large dependency trees, and tech leads reviewing upgrade risk before a sprint all use this to make informed upgrade decisions without reading through GitHub release pages manually.

Claude fetches current documentation and helps you assess upgrade risk. Tell it what version you are on and what version you are targeting — it retrieves the relevant migration notes, identifies the breaking changes that affect your usage pattern, and explains the migration steps in plain language.
How to check for breaking changes before upgrading
Once connected (see setup above), use the Library Docs tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Ask: "Get the docs for [package], specifically what changed in version [X]"
- Claude retrieves the changelog and migration guide
- Describe your current usage: "I use the X method with Y parameter — does this still work?"
- Claude assesses the impact on your specific code and outlines migration steps
Example prompt
Try this with the Library Docs tool
Get the documentation for React Router v7 and tell me what broke compared to v6. I use useNavigate, useParams, and nested routes extensively.
Tips
- Describe your current usage pattern so Claude can assess impact accurately rather than listing all changes
- Ask Claude to rank the breaking changes by severity for your specific use case
- Request a migration checklist you can use to track progress through the upgrade
