codebase-migration-batches SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

codebase-migration-batches from yeaight7/agent-powerups is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add yeaight7/agent-powerups/codebase-migration-batches@git:20260606.f44b3f5

Pins git:20260606.f44b3f5 in mdr.lock. Pin the fingerprint instead.

Use when a wide refactor or migration is too large to ship as one change — API renames across many files, framework or config migrations, or mechanical codemod-backed refactors that need reviewable batches.

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

# Codebase Migration Batches

Use this skill for broad, repetitive refactors that should move in slices.

## When to Use

- API renames across many files
- Framework or config migrations
- Mechanical refactors backed by codemods or search/replace rules
- Any change where "all at once" would be too large to review safely

## Core Rules

- Define the transform precisely before editing files
- Keep one migration theme per batch
- Prefer deterministic codemods over manual repetition
- Maintain a batch ledger so already-migrated files are not touched twice
- Validate each batch before moving to the next
- No auto-commit, auto-push, or auto-PR

## Workflow

1. **Define the migration**
   - What changes
   - What does not change
   - How success is measured

2. **Measure the blast radius**
   - Count affected files
   - Sample representative files
   - Identify edge cases before the first codemod pass

3. **Choose batch size**
   - Small enough to review and debug
   - Large enough to make visible progress

4. **Run the transform**
   - Prefer AST-aware tools when syntax matters
   - Use plain search/replace only for truly mechanical edits

How to install

The exact contents, by fingerprint
mdr add yeaight7/agent-powerups/codebase-migration-batches@sha256:b60190868d47d40a

The line at the top of this page pins the label git:20260606.f44b3f5, 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.
