Names the domain (form migration) and identifies the two systems involved (JsonForm/FormModel to TanStack-based), but doesn't list specific concrete actions like 'convert field definitions', 'update validation logic', or 'replace form components'.

Describes what it does (guide for migrating forms between two systems) but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric should cap completeness at 2, and the 'what' is also fairly thin—just 'guide for migrating'—so it falls to 1.

Includes relevant technical terms like 'JsonForm', 'FormModel', 'TanStack', and 'migrating forms' that a developer would use, but misses common variations like 'refactor forms', 'upgrade forms', 'form refactoring', or 'legacy form replacement'.

The description targets a very specific migration path between two named systems (JsonForm/FormModel → TanStack), making it highly distinctive and unlikely to conflict with other skills.

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.

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.

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.

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.
