Structured workflow for upgrading Next.js applications across major versions. Use when migrating a Next.js project from one major version to another (e.g., 13 to 14, 14 to 15, 15 to 16). Covers codemod automation, breaking change detection, incremental migration paths, and post-upgrade validation.
Uses 1M context window to ingest an entire codebase and output a file-by-file migration plan. Supports JS to TS, React class to hooks, framework migrations, and more. Generates migration-plan.md with file inventory, dependency graph, migration order, file-by-file changes, estimated effort, and risk assessment.
Technology stack evaluation and comparison with TCO analysis, security assessment, and ecosystem health scoring. Use when comparing frameworks, evaluating technology stacks, calculating total cost of ownership, assessing migration paths, or analyzing ecosystem viability.
Generate migration deliverables for bringing relevant Megatron changes into MindSpeed after branch alignment and impact mapping are complete. Use when Codex already has a confirmed MindSpeed-to-Megatron branch pairing and needs to produce a migration report, candidate patch, or guarded workspace edits instead of redoing upstream analysis from scratch.
Use when the user asks to write SQL queries, optimize database performance, generate migrations, explore database schemas, or work with ORMs like Prisma, Drizzle, TypeORM, or SQLAlchemy.
Create and manage database migrations safely with rollback support. Use when modifying database schema, adding indexes, or managing database changes.
Manage technical debt by producing a Tech Debt Management Pack (debt register, scoring/prioritization, refactor vs rewrite decision memo, incremental paydown plan, migration/rollback plan, metrics, and stakeholder cadence). Use for tech debt, refactoring, legacy modernization, and migrations.
Use when comparing technology stacks, evaluating frameworks/providers, or assessing TCO, security, and ecosystem health for migration decisions.
Run database migrations in Medusa
Use when implementing data persistence in iOS apps with SwiftData or CoreData, encountering migration errors, performance issues with fetches, or choosing between persistence frameworks
Breaking changes documentation, migration guides, deprecation process, and versioning. Use when introducing breaking API changes, creating migration guides, deprecating features, updating changelogs, managing major version releases, or documenting version transitions. Triggered by keywords like breaking changes, migration guide, deprecation notice, version upgrade, changelog update, breaking API modification.
Use this skill when designing SDKs, writing onboarding flows, creating changelogs, or authoring migration guides. Triggers on developer experience (DX), API ergonomics, SDK design, getting-started guides, quickstart documentation, breaking change communication, version migration, upgrade paths, developer portals, and developer advocacy. Covers the full DX lifecycle from first impression to long-term retention.
