Conciseness

About 30 lean lines that explain only project-specific facts Claude cannot know ("The trigger re-renders the page through its own new or edit action with the submitted values assigned", "The engine defines the concern") and explicitly refuses to restate the README ("This skill does not restate it"); every token earns its place with no padding or explanation of known Rails/Turbo concepts.

Actionability

Fully executable, copy-paste ready guidance: `bin/rails generate turbo_form:install`, the `resources :products, concerns: :turbo_form` route snippet, and the `simple_form_for @product, dynamic: true` slim example with `dynamic_trigger: true` covering the common dependent-dropdown case plus the mechanics of why the second select fills.

Workflow Clarity

Setup is clearly sequenced ("Check the Gemfile for turbo_form. If it is missing, add it and run `bin/rails generate turbo_form:install`, then draw the `:turbo_form` route concern"), but the legacy-conversion path ("convert it to turbo_form and delete the route, action, view, and spec helper usage it no longer needs") is a multi-step refactor with no verification checkpoint such as running the system specs before deleting the old wiring — a minor validation gap that fits anchor 4 rather than 5.

Progressive Disclosure

Under 50 lines with no bundle files needed; sections (Setup, Shape, legacy turbo_fetch handling) are well organized and the one external reference is clearly signaled at one level deep: "The gem's README is the API documentation. Read it before writing or changing a dynamic form. This skill does not restate it."

Specificity

"Build forms that change as they are filled in — cascading or dependent dropdowns, conditional fields and sections, option lists that depend on another field, STI type switches — with the turbo_form gem" lists multiple concrete capabilities covering the whole dynamic-form domain; it is not score 4 because there are no coverage gaps within its niche.

Completeness

Explicitly answers both: what ("Build forms that change as they are filled in … with the turbo_form gem") and when ("Use when a form must update without a full page reload, when adding or changing a dynamic form, or when touching existing turbo_fetch routes, actions, or turbo-form/turbo-fetch Stimulus wiring") with concrete trigger phrases.

Trigger Term Quality

Natural phrases a user would actually say are all present — "cascading or dependent dropdowns" (a synonym pair), "conditional fields and sections", "dynamic form", "update without a full page reload" — plus tool-specific terms ("turbo_fetch", "turbo-form/turbo-fetch Stimulus wiring"); matches the comprehensive-with-synonyms anchor, not 4, since no common variation is missing.

Distinctiveness Conflict Risk

Clear niche — dynamic forms via the turbo_form gem in RoleModel Rails apps — with distinct tool-specific triggers (turbo_form, turbo_fetch, turbo-form controller), so minimal risk of triggering for the wrong skill; not 4, since it does not overlap with any closely related generic skill.
