Conciseness

The body is efficient: a complete copy-paste Quick Start, terse Key Concepts entries with minimal prose, and no explanation of what Adaptive Cards or C# are. It misses the 5 anchor because the 'When to Use This Skill' section re-lists the frontmatter's trigger cases ('Adding toggle switches or dropdown menus', etc.) and the opening sentence restates the description — minor redundancy that could be trimmed. It is clearly above the 3 anchor, which requires 'some unnecessary explanation' beyond this light duplication.

Actionability

Fully executable guidance: a complete, copy-paste-ready C# ContentPage/FormContent pair including the TemplateJson, submit handler, and registration snippet, followed by concrete deploy-and-test steps ('run Reload, navigate to your form and submit it') and small executable DataJson/mixed-content examples. The 'for common cases, fully executable' anchor fits; the 4 anchor's 'minor gaps' would require missing key details, and none are evident.

Workflow Clarity

A clear three-step sequence — create the page, register it in CommandsProvider, deploy/test with the explicit 'run Reload' checkpoint — covering the common case end to end. Not the 5 anchor because there is no error-recovery feedback loop (e.g., what to do if the form fails to render or submit) and no explicit validation of the JSON or payload beyond the null check in the code; not a 3 because the test step is a concrete checkpoint, not merely 'implicit'.

Progressive Disclosure

The 145-line SKILL.md is an overview, and the bulk material (536 lines of template JSON and handler code for common form types) is split into references/form-patterns.md, clearly signaled as 'See [form-patterns.md](references/form-patterns.md) for template JSON for common form types'. The reference is one level deep, verified to exist, and the body sections are well organized — matching the clear-overview/one-level-deep anchor rather than the 4 anchor, which expects organization gaps.

Specificity

Names the domain ('form-based UI for your Command Palette extension using Adaptive Cards') and enumerates concrete deliverables ('toggle switches, text inputs, dropdown menus, ... configuration dialogs, or interactive content pages'), matching the 'several specific actions; minor gaps' anchor. It falls just below the 5 anchor because the only stated capabilities are creating form UI and 'Supports the Adaptive Cards Designer' — submission handling, data binding, and other capabilities shown in the body are absent, and the enumerated items are use cases rather than distinct actions.

Completeness

Explicitly answers both: what — 'Create form-based UI for your Command Palette extension using Adaptive Cards'; when — 'Use when asked to add forms, user input fields, toggle switches, text inputs, dropdown menus, data entry, surveys, configuration dialogs, or interactive content pages'. This matches the 5 anchor's structure ('what' plus a 'Use when' clause with concrete trigger phrases), not the 4 anchor where 'when could be more explicit or specific'.

Trigger Term Quality

The 'Use when' clause covers natural terms comprehensively with synonyms: 'forms, user input fields, toggle switches, text inputs, dropdown menus, data entry, surveys, configuration dialogs, or interactive content pages' — a user asking for any of these would naturally phrase it this way. It clearly matches the comprehensive-synonyms anchor; the 4 anchor ('a few natural terms missing') understates this coverage.

Distinctiveness Conflict Risk

'Command Palette extension' and 'Adaptive Cards' pin it to a clear niche with distinct triggers, and the enumerated trigger terms are form-specific rather than generic. Minimal conflict risk with other skills; the generic-sounding 'interactive content pages' is the only mild overlap term, keeping it at 5 rather than suggesting any real ambiguity.
