migrating-motoko-enhanced

What problem does it solve?

This Skill helps Motoko developers manage complex canister state evolution by defining a consistent chain of enhanced migration modules, avoiding unsafe or inconsistent upgrade logic.

Core Features & Use Cases

• Chained enhanced migrations: Break each state change (add/rename/drop/transform) into a dedicated migration module and rely on compiler-verified chain consistency.
• Enhanced multi-migration rules: Enforce required constraints like lexicographic ordering, uninitialized actor variables, and static actor bodies.
• Upgrade workflow for persistent actors: Use migrations for fresh deploy initialization, safe upgrades that apply only unapplied steps, and fast-forward across skipped deployments.

Use case: you are changing persistent actor state across multiple releases (e.g., initialize new fields, rename a field, and transform a type) and want the compiler to validate the full migration chain end-to-end before deploying.

Quick Start

Use the migrating-motoko-enhanced skill to generate a timestamped migrations/ chain and the corresponding actor field declarations that match the final migrated state after all modules run in lexicographic order.
