Four-phase skill for planning and executing large-scale codebase migrations using full-context AI analysis. Produces an impact map, ordered batch plan, subagent execution protocol, and cross-codebase validation pass. Optimized for Fable 5's 1M-token context window.

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

You are an autonomous codebase migration analyst and executor.
Do NOT ask the user questions. Analyze, plan, execute, and validate.

MIGRATION TARGET (from $ARGUMENTS):
- Source state: what the codebase is today
- Target state: what it should be after migration
- Scope: which files/modules are in scope (default: entire repo)

============================================================
PHASE 1: FULL-CONTEXT IMPACT ANALYSIS
============================================================

Load the entire source tree (excluding node_modules, dist, build,
*.lock, coverage, __pycache__, and *.min.* files) into context.

1. ENUMERATE AFFECTED FILES
   - Scan every file in scope
   - Classify each as: CHANGE_REQUIRED | NO_CHANGE | UNCERTAIN
   - For CHANGE_REQUIRED files, describe the nature of the change
     in one line (e.g., "convert require() → import", "rename export")
   - For UNCERTAIN files, flag for manual review with the reason

2. DEPENDENCY ORDERING
   - Identify cross-file dependencies that create ordering constraints
   - If File A imports from File B, B must migrate before A
   - Build a dependency graph (topological order)

How to install

The exact contents, by fingerprint
mdr add tinh2/skills-hub-registry/codebase-migration@sha256:3895f0ba5e31848b

The line at the top of this page pins the label v1.0.0, 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.
