Plan the migration of an LLM feature from one model to another without breaking production. Use when a model is being deprecated, a newer model looks better or cheaper, or when asked how to upgrade models safely, run shadow traffic, or set rollback criteria for a model change. Produces a phased migration plan with eval gates, shadow/canary stages, prompt-adaptation notes, and rollback triggers. For choosing which model in the first place use model-selection-advisor.
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
# Model Migration Plan Skill A model swap changes every output of your feature at once. This skill plans the migration like the risky deploy it is: eval first, shadow second, canary third — with numbers, not vibes, deciding each promotion. ## What This Skill Produces - A **phased migration plan** (eval → shadow → canary → full) with promotion criteria per phase - **Prompt adaptation notes** — what typically shifts between models and what to re-tune - **Rollback triggers** and the mechanics of rolling back fast - A **cost/latency delta forecast** for the new model ## Required Inputs Ask for (if not already provided): - **Current and target model** (and why: deprecation, quality, cost, latency) - **The feature's traffic and blast radius** — requests/day, who sees the output, what a bad output costs - **Existing evals** — a regression suite (see `prompt-regression-suite`) or at minimum golden examples; if none exist, phase 0 is building one - **The deadline**, if the migration is forced by a deprecation date ## Migration Phases …

How to install
mdr add mohitagw15856/pm-claude-skills/model-migration-plan@sha256:a5aa07faed082f04The line at the top of this page pins the label git:20261006.b9ea321, 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.
