The problem
Framework and library upgrades are postponed because the migration work is tedious.
How the agent works
The agent bumps a dependency, reads the changelog/migration guide, fixes compile and test failures, and opens a PR describing the changes.
Setup steps
- Upgrade one major dependency at a time
- Give the agent the migration guide link
- Let it run build and tests repeatedly
- Review the diff carefully
- Deploy behind normal release process
Tools that can do this
- Claude Code
- Codex
- Devin
- Renovate + coding agent
