Sample input
Scan my Next.js project and create a migration plan to move from the Pages Router to the App Router. Identify which components will be the most difficult to convert.
Sample output
I've analyzed 24 files. Phase 1: Setup 'app' directory and root layout. Phase 2: Migrate 12 stateless components (Low effort). Phase 3: Refactor 4 'getServerSideProps' pages to Server Components (Medium effort). Phase 4: Convert 'useRouter' hooks in 3 client components (High effort).

About This Skill
Professional Framework Modernization
Modernizing a codebase is one of the most high-risk tasks a developer faces. This skill transforms your AI agent into a Senior Tooling Engineer capable of planning and executing complex framework migrations with surgical precision. It replaces generic "best effort" rewrites with a structured, multi-phase engineering process.
What it does
The skill provides a rigorous four-phase framework for any major code transition:
- Readiness Assessment: Scans your dependency tree and source code to identify breaking changes and deprecated APIs before a single line is changed.
- Phased Planning: Breaks the migration into logical, testable increments (e.g., config changes vs. core API swaps) to prevent "big bang" failures.
- Intelligent Transformation: Applies specific code patterns for migrations like Next.js Pages to App Router, React Class components to Hooks, or Python version upgrades.
- Verification: Enforces automated checks including type-checking, linting, and regression testing to ensure the new version is production-ready.
Why use this skill?
Standard LLMs often hallucinate deprecated parameters or mix versions during a migration. This skill forces the agent to consult official migration paths, map dependencies correctly, and write rollback instructions, ensuring you never get stuck in a half-migrated state with a broken build.
Use Cases
- Convert legacy React class components to modern functional components with hooks.
- Transition Express.js APIs to Fastify for improved performance and validation.
- Modernize Python codebases using latest PEP 585 and 604 type hint syntax.
- Map and resolve breaking changes during major Next.js or Angular version bumps.
- Generate step-by-step rollback procedures for high-risk architectural shifts.
Known Limitations
- Requires project access to scan dependencies and files. - Manual verification needed for complex state logic and runtime side effects. - Cannot resolve 3rd-party library version conflicts automatically.
