Conciseness

Nearly all content is project-specific API knowledge Claude cannot know (useScrapsForm, defaultFormOptions semantics, FieldErrors contract, auto-save triggers per field type), so tokens mostly earn their place. It sits at score 4 rather than 5 because of noticeable duplication: form-reset-after-save guidance appears twice as full sections ('Resetting After Save' and 'Form Reset After Save'), defaultFormOptions importance is explained three times, and the confirm-prop section gives five overlapping examples that could be trimmed. It is well above the score-3 anchor since padding is the exception, not the rule.

Actionability

Fully executable, copy-paste-ready TSX examples cover the common cases end to end: complete useScrapsForm usage, all nine field types (input, number, select single/multiple, switch, textarea, range, radio, custom BaseField), layouts, Zod schema patterns including the nullable-refine z.input/z.output flow, server error mapping with setFieldErrors, AutoSaveForm with mutationOptions, and confirm dialogs. Paired ❌/✅ do-and-don't pairs make the correct path unambiguous.

Workflow Clarity

The 'Quick Reference Checklist' provides an explicit ordered sequence for both form creation and auto-save fields, and the surrounding sections supply the validation checkpoints it references: schema validation via validators:{onDynamic}, error recovery via narrowing to RequestError and setFieldErrors, conditional field-level validators, and reset-after-save. The feedback loops (validate → show field errors, mutate → setFieldErrors, save → form.reset) match the score-5 anchor including its checklist criterion.

Progressive Disclosure

No bundle files (references/, scripts/, assets/) exist, and this ~1,100-line SKILL.md inlines everything: a full field-component catalog, layout reference, auto-save behavior tables, and an extensive do's-and-don'ts section — material that belongs in one-level-deep reference files per the rubric rationale. Internal section structure and the closing File References table are good, which keeps it above the score-2 'minimal structure' anchor, but it matches score 3's 'content that should be separate is inline'. The one delegation attempt — a relative link to '../../../static/app/components/core/form/fields.mdx#checkbox-group' — points outside the skill bundle to a path that cannot be verified and is unlikely to resolve from the skill's directory.

Specificity

The description names its domain ("Sentry's new form system") and enumerates several concrete capabilities: "creating forms", "form fields", "display-only form content", "validation", and "auto-save functionality". It matches the 'lists several specific actions; minor gaps' anchor rather than 5 because the 'what' is carried by a single verb phrase ('Guide for creating forms') and could enumerate more actions (layouts, error handling, field grouping); it is well above the 1–2 concrete actions of the score-3 anchor.

Completeness

It explicitly answers both questions: the 'what' is "Guide for creating forms using Sentry's new form system" and the 'when' is an explicit "Use when implementing forms, form fields, display-only form content, validation, or auto-save functionality" with concrete trigger phrases. This matches the score-5 anchor's structure (clear what + explicit Use-when with concrete triggers) and clearly exceeds score 4, where the 'when' is present but vague.

Trigger Term Quality

Natural trigger terms are present and would be said by users: "forms", "form fields", "validation", "auto-save", "display-only form content". It falls short of the score-5 comprehensive anchor because common synonyms are missing — e.g., 'input fields', 'form validation', 'settings forms', or named technologies like 'React'/'Zod' that a user might mention.

Distinctiveness Conflict Risk

"Sentry's new form system" carves out a clear niche with distinct, form-scoped triggers, so it is unlikely to fire for unrelated skills. It stops short of score 5 because broad terms like "validation" and "auto-save functionality" could overlap with a generic validation or persistence skill outside the form context; it is more distinct than the score-3 'somewhat specific but could still overlap' anchor.
