This is a highly actionable migration guide with excellent concrete code examples covering every feature mapping from old to new system. Its main weaknesses are length/verbosity (the document is very long with all details inline rather than progressively disclosed) and the lack of explicit validation/verification checkpoints in the migration workflow. The feature mapping table is an effective overview, but the body could benefit from splitting detailed examples into referenced files.
Suggestions
Add explicit validation checkpoints to the migration checklist, such as 'Run the component's test suite to verify behavior is preserved' and 'Manually test the form in the browser before committing'.
Consider splitting the detailed old/new code comparisons into a separate MIGRATION_EXAMPLES.md file, keeping only the feature mapping table and brief summaries in the main SKILL.md.
Trim explanatory prose that describes what old features did (e.g., 'The saveMessage showed a custom toast/alert after successful save') — Claude can infer this from the code examples alone.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is quite long (~400+ lines) with extensive old/new code comparisons that are useful but could be tightened. Some sections include explanatory prose that Claude doesn't need (e.g., explaining what getData did, what saveMessage showed). The mutation typing section is thorough but borders on verbose with multiple anti-pattern examples. However, most content is genuinely migration-specific knowledge Claude wouldn't have. | 2 / 3 |
Actionability | Excellent actionability throughout — every feature mapping includes concrete, executable old-vs-new code examples with real imports, real component names, and copy-paste-ready patterns. The mutation typing section provides clear do/don't examples. The migration checklist at the end is a concrete action list. | 3 / 3 |
Workflow Clarity | The migration checklist at the end provides a clear sequence of steps, and individual feature migrations are well-documented. However, there are no explicit validation checkpoints — no 'verify the form works after this step' or 'run tests to confirm' instructions. For a destructive operation like migrating forms, the absence of verification steps (e.g., 'run the test suite', 'verify search indexing works') is a gap. The FormSearch section does include the extract-form-fields command, which is a validation step, but overall validation is sparse. | 2 / 3 |
Progressive Disclosure | The content is a monolithic document with no references to external files for detailed content. The feature mapping table at the top is a good overview, but the detailed sections that follow are all inline, making this a very long single file. The mutation typing rules reference 'static/AGENTS.md' which is good, but the bulk of content (especially the many old/new code comparisons) could benefit from being split into separate reference files with the SKILL.md serving as an overview. | 2 / 3 |
