webiny-form-model

Building forms with the FormModel system — field types, renderers, layout, validation, conditional rules, computed fields, and dynamic zones. Use this skill when the developer needs to define form fields with the builder API, choose renderers, build layouts with tabs/rows/separators, add validation (Zod or imperative), use conditional visibility/disable rules, create computed fields, or work with object fields and templates (dynamic zones).

Quality

Content

63%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized, highly actionable API reference: nearly every section delivers executable TypeScript with settings tables and defaults, and navigation via headers is easy. Its weaknesses are token efficiency — duplicated `.context()` and conditional-visibility examples cost roughly 100 lines — and the absence of progressive disclosure, with the entire reference inlined in one large file instead of split into referenced files.

Suggestions

Move the complete field-type and renderer reference tables into a reference file (e.g., references/renderers.md) and keep only the most common examples in SKILL.md, linking to it clearly.

Consolidate the duplicated `.context()` examples — keep them either in "Callback Parameters" or "Field Context", not both sections — and merge "Conditional Rules" with "Conditional Visibility / Disable (callback form)".

Add one complete end-to-end form model example (fields + layout + validation assembled) near the top so the reference snippets have a concrete anchor context.

DimensionReasoningScore

Conciseness

The body is dense reference material with no time wasted on concepts Claude already knows, but it is noticeably redundant: `.context()` examples appear in both the "Callback Parameters" section and again across four sub-sections of "Field Context", and conditional visibility is covered twice ("Conditional Rules" and "Conditional Visibility / Disable (callback form)"). This fits anchor 3 ('mostly efficient but could be tightened') better than anchor 4's 'minor instances'.

3 / 5

Actionability

Nearly all guidance is concrete, executable TypeScript (builder chains, renderer settings, rules objects, form API calls) that is copy-paste ready. Minor gaps keep it from anchor 5: several snippets contain `...` placeholders (dynamic zone templates) and there is no complete end-to-end form model definition showing fields, layout, and validation assembled together.

4 / 5

Workflow Clarity

This is a reference-style skill with no destructive or batch operations, so the validation-cap does not apply; the simple-skill exception for a single unambiguous action partially fits. Sections are logically sequenced (fields → common methods → renderers → layout → validation → conditional rules → callbacks → computed → form API) and the TL;DR states the pattern up front, but no full example ties the sequence together. Anchor 4's 'clear sequence with minor gaps' is the best fit.

4 / 5

Progressive Disclosure

No bundle files exist, and roughly 790 lines of complete API reference (all field types, full renderer table, all rule/operator tables) are inlined in SKILL.md rather than split into one-level-deep reference files. Structure and headers are good — so above anchor 2's 'minimal structure' — but content that clearly belongs in separate files is inline, matching anchor 3.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: it states concrete capabilities in third person and pairs them with an explicit, multi-trigger 'Use this skill when...' clause covering all major feature areas. The only gap is modest synonym coverage (no mention of Webiny or alternative user phrasings).

DimensionReasoningScore

Specificity

The description enumerates concrete, distinct capabilities — "field types, renderers, layout, validation, conditional rules, computed fields, and dynamic zones" — giving comprehensive coverage of the skill's actions rather than generic language. Anchor 4's 'minor gaps in coverage' doesn't apply since every major capability area is named.

5 / 5

Completeness

Both questions are answered explicitly: the first sentence states what the skill does ("Building forms with the FormModel system — field types, renderers, layout, validation...") and the second gives a concrete trigger clause ("Use this skill when the developer needs to define form fields... create computed fields, or work with object fields and templates"). This matches anchor 5 exactly.

5 / 5

Trigger Term Quality

Strong natural-phrase coverage: "define form fields with the builder API", "choose renderers", "build layouts with tabs/rows/separators", "add validation (Zod or imperative)", "conditional visibility/disable rules", "dynamic zones". It falls short of anchor 5's synonym-level coverage — terms like "Webiny", "form builder", or generic "admin form" phrasings are absent.

4 / 5

Distinctiveness Conflict Risk

The description carves out a clear niche (Webiny's FormModel declarative form system) with distinct triggers — renderer selection, dynamic zones, Zod validation, computed fields — that would not naturally fire for unrelated form or document skills. Minimal conflict risk.
