Conciseness

The body is dense specification where nearly every token earns its place: the activation boundary bullets ('A first turn or new project does not by itself require a form'), the full field spec, and the convergence condition are all non-obvious information Claude cannot infer. Minor trimming opportunities exist — the `default` bullet spans a second, awkwardly-joined paragraph ('Prefill each non-visual question suitable for a recommendation; omit `default` only when...') that could be consolidated, and 'A reference file remains unanswered until supplied' is cryptic. Not score 5 because of these small over-explanations; not score 3 since the padding is minor, not whole unnecessary explanations.

Actionability

The emission shape includes a complete, copy-paste-ready `<question-form>` JSON example covering the common control types (checkbox with maxSelections, radio with object options, select with grouped language values, file), and the question-object section exhaustively specifies every field: 'id', 'label', the enumerated 17 `type` values, `default` value semantics per control type, `options` formats, `allowCustom`, `customLabel`, and `required`. Concrete rules like 'Choose `radio` vs `select` by option count' and 'Keep each `label` under ~40 characters' make the guidance fully executable.

Workflow Clarity

The protocol has a clear implicit sequence: Activation boundary (when to emit) → Emission shape (how to emit) → Convergence (completion condition: 'completes when the next user message contains an answer for every required question', with the follow-up rule 'do not ask the same questions again unless later input invalidates an answer'). This is an instruction-only skill with no destructive or batch operations, so no validation cap applies. Score 5 would require explicit feedback-loop handling for edge cases such as invalid or partially-answered submissions, which is only implied.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/ directories), so the skill is a single self-contained document with well-organized sections (Activation boundary, Emission shape, Question object shape, Convergence) and no nested or buried references. The ~130-line body is cohesive spec rather than content that clearly belongs in separate files. Score 5 is reserved for well-organized skills under 50 lines or with clearly split one-level-deep references; at this length the question-object field spec could arguably live in a reference file, keeping it at 4.

Specificity

The description names the domain — "Structured clarification form" — but offers only a minimal, generic action; it describes an artifact ("a form") rather than concrete actions Claude performs. This matches the anchor 'Names the domain but actions are minimal or generic' ("Processes PDF files"), not score 3, which requires 1-2 concrete actions, and not score 1, since the domain is at least named specifically.

Completeness

The 'what' is fairly clear (a structured clarification form for unresolved material requirements), but there is no 'Use when...' clause or any trigger guidance — the 'when' is entirely absent. Per the judging guideline, a missing 'Use when...' clause caps completeness at 3; score 4 would require at least a weakly explicit 'when'.

Trigger Term Quality

Keywords are mostly technical jargon: "unresolved material requirements" is spec-speak users would not naturally say; "clarification" is the only semi-natural term. This sits between 'no natural keywords; only technical jargon' (1) and 'some relevant keywords but missing common variations' (3) — it has one or two generic keywords but misses natural phrases like 'ask questions', 'gather requirements', 'brief', or 'clarify'.

Distinctiveness Conflict Risk

"Structured clarification form" carves out a somewhat specific niche (question forms during discovery), but the generic terms 'clarification' and 'requirements' could overlap with other discovery, planning, or requirements-gathering skills. It is more specific than 'Works with document files' (3) but lacks the distinct trigger phrases needed for 4-5.
