Use when migrating APIs, libraries, or patterns across a large codebase and a single mega-commit would be too risky to review or merge.
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
## Purpose
Never attempt to migrate an entire codebase in a single step. Mega-commits are impossible to review and dangerous to merge. Migrate in verified, committed slices, tracking the remaining inventory to zero.
## When to Use
- Replacing an API, library, or pattern with many call sites
- A framework or major-version upgrade touches a wide surface area
- A previous big-bang migration attempt stalled or was reverted
## Inputs
- The "Old Way" and "New Way" definitions
- The repo's test command
## Workflow
1. **Define the target pattern.** Clearly establish the "Old Way" and the "New Way".
2. **Build the inventory.** Make the migration measurable:
```bash
git grep -ln "oldApiCall(" -- "src/" # files still on the Old Way
git grep -c "oldApiCall(" -- "src/" | sort -t: -k2 -nr # hotspots first
```
3. **Implement side-by-side.** Create the "New Way" implementation alongside the old one. Do not delete the old one yet.
4. **Migrate one vertical slice.** Pick exactly one feature, route, or component; update it to use the new pattern. Mechanical rewrites can be scripted per slice:
```bash
…Read the whole file at its exact version.
How to install
mdr add yeaight7/agent-powerups/incremental-migration@sha256:b9e6995a9779e5bcThe line at the top of this page pins the label git:20260606.da26913, 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.
