Can this help with the Langfuse v2 to v3 transition?

Absolutely. It covers specific breaking changes like the change from default to named imports and the shift in how trace and flush methods operate.

How do I rollback if an upgrade fails?

The skill includes a rollback plan using git and package managers to revert to previous stable versions and lock files.

Does it automate the code changes?

It provides codemod script templates (using ts-morph) and CLI commands that can be used to automate the update of imports and method calls across your project.

Does this skill support both Python and TypeScript?

Yes, it provides specific migration paths, code examples, and testing patterns for both the langfuse-js and langfuse-python SDKs.

Upgrades Langfuse SDKs and migrates codebase patterns to resolve breaking changes across TypeScript and Python environments.

This skill provides a comprehensive framework for managing Langfuse SDK upgrades, ensuring smooth transitions between major versions. It guides developers through version auditing, identifying breaking changes in API signatures—such as the shift from async to sync trace methods—and implementing automated codemods to update codebase imports and function calls. By integrating standardized testing templates and rollback strategies, it minimizes the risk of breaking observability pipelines during critical SDK maintenance tasks.
