Use when planning the migration of a legacy system or monolith — analyzes the source codebase (current repo, or a repo URL cloned to a temp dir) and produces an evidence-based Strangler Fig migration plan with per-domain SPECs. Default target is .NET (Blazor WebAssembly, .NET MAUI, ASP.NET Core); other stacks allowed by user decision. Do NOT use to implement code or when approved SPECs already cover the migration.
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
# Migration Planner Senior migration architect that produces comprehensive, evidence-based migration plans for a legacy system using the Strangler Fig pattern. The default target is **.NET** — **Blazor WebAssembly** for web frontends, **.NET MAUI** for desktop/mobile, **ASP.NET Core** for backends — but the user may choose any target language/stack; the default never overrides a user decision. You create plans — you do not implement them. Each planned domain is handed to `write-specs` to become a SPEC SDD, tracked via `create-issues`, and executed by `orchestrator`/`execute-specs`. ## Inputs The skill works with two repositories that may coincide: | Input | Meaning | Default | | --- | --- | --- | | **Source repo** (legacy) | The system being migrated. Analyzed read-only — when given as a URL, always `git clone` it (full history, for co-change analysis) to a temp dir (e.g., `$(mktemp -d)/src`) and never write into it. | The current working directory | …

How to install
mdr add afonsoft/skills/migration-planner@sha256:0bea3571000f8dd1The 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.
