This is a well-structured migration guide that efficiently covers multiple source platforms with concrete before/after code examples and a useful error reference table. The decision tree and platform comparison table are excellent for quick orientation. The main weakness is the migration checklist lacking explicit validation checkpoints and error recovery loops, which is important for migration workflows that can fail in subtle ways.
Suggestions
Add validation checkpoints to the migration checklist, e.g., after step 2 (Convert to ESM): 'Run wrangler dev and verify no import errors before proceeding' and after step 4: 'Verify all storage operations work against R2/KV before continuing'.
Include a feedback loop in the checklist for when CPU limits are exceeded in step 7, such as specific strategies to diagnose and fix (e.g., 'If exceeded, profile with wrangler dev --inspect, then chunk computation or offload to Durable Objects').
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient throughout. It uses tables, decision trees, and code examples without explaining basic concepts Claude already knows. Every section delivers actionable migration-specific information without padding. | 3 / 3 |
Actionability | Provides fully executable before/after code examples for Lambda, Express, and environment variable patterns. The error table gives specific solutions, and the compatibility flags section includes a concrete wrangler.jsonc configuration. | 3 / 3 |
Workflow Clarity | The migration checklist provides a clear sequence of steps, but lacks explicit validation checkpoints and feedback loops. For a migration involving potentially destructive changes, there's no 'validate -> fix -> retry' pattern — just 'Test Locally' and 'Performance Test' as final steps without error recovery guidance. | 2 / 3 |
Progressive Disclosure | The skill provides a clear overview with well-signaled references to detailed migration guides (lambda-migration.md, vercel-migration.md, etc.) via the 'When to Load References' table. The 'See Also' section provides additional navigation. Content is appropriately split between overview and referenced files. | 3 / 3 |
