Drives a major-version framework bump as a sequence of small, reversible, CI-gated PRs using official codemods and changelog diffing while keeping the app green. Use when bumping React, Rails, Spring Boot, Angular, or any framework across a major version with breaking API/config changes; do NOT use for language or runtime version jumps (Python 2 to 3, Node majors, Java LTS) - use language-version-migrator instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Framework Upgrader Treat a major-version framework upgrade as a sequence of small, mergeable, reversible PRs against a green main, driven by the framework's official migration path. A single long-lived upgrade branch is the failure mode. ## Workflow 1. **Diff the changelog into a concrete edit list.** Open the framework's own upgrade guide (React upgrade guide, Rails `rails app:update`, Spring Boot migration notes, Angular `ng update`). Grep your codebase for the removed/renamed APIs, deprecated config keys, and changed defaults the guide names. Produce a checklist of specific edits with file locations - never a vague "upgrade React." Split each item into required-now vs. deferrable-deprecation. 2. **Get green on the current major first.** Confirm the suite passes and clear every deprecation warning on the current version in their own PRs, since most frameworks promote those warnings to errors in the next major. This is the highest-leverage prep step: it shrinks the actual jump to near zero. Never skip an intermediate major - walk one major at a time (4→5→6, not 4→6), because guides and codemods assume single-step jumps. …

How to install
mdr add skillmedev/skills/framework-upgrader@sha256:130ebccc9cfbbdfeThe line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
