Conciseness

The body is exactly two lines — a title and "This fixture exists for Skills SDK scenario-quality receipt tests." — with zero padding and no explanation of concepts Claude already knows, matching anchor 5 ('Lean and efficient; every token earns its place'). Nothing can be trimmed, so scores below 5 do not apply.

Actionability

"This fixture exists for Skills SDK scenario-quality receipt tests." only describes the file's purpose — there is no code, command, or instruction of any kind, matching anchor 1 ('Entirely vague or abstract; only describes rather than instructs'). It is below score 2 because even that anchor's high-level hints ('Import pdfplumber and use it to open the PDF') are absent here.

Workflow Clarity

No steps or sequence exist anywhere in the body — nothing to sequence or validate, matching anchor 1 ('Steps missing or incoherent; no sequence'). The simple-skill exception cannot rescue it: a single action scoring 5 requires that action to be unambiguous, and the body specifies no action at all.

Progressive Disclosure

The body has minimal structure (a single H1, no sections) and the bundle contains references/evals.yaml that is never referenced or signaled from the body, matching anchor 3 ('Some structure but could be better organized; references present but not clearly signaled'). It is below score 4 because that anchor requires references to be mostly clearly linked, and below the under-50-line 5 because there are no well-organized sections and an orphaned bundle file.

Specificity

"Fixture skill with promotable eval scenario metadata" names a concrete domain (fixture, eval scenario metadata) but contains no action verbs whatsoever — it states identity, not capability, matching anchor 2 ('Names the domain but actions are minimal or generic'). It is above score 1 because the domain is specific rather than pure abstraction like 'Helps with documents', but below score 3 because unlike 'Processes PDF files and extracts content' it lists no concrete actions at all.

Completeness

The 'what' is vague — "Fixture skill with promotable eval scenario metadata" describes what the artifact is, not what it does — and there is no 'when' or equivalent trigger guidance, matching anchor 2 ('Has a vague what and no when'). It is below score 3 because that anchor requires a clear 'what' (a concrete capability), and the missing 'Use when...' clause caps completeness at 3 regardless.

Trigger Term Quality

There are no natural keywords a user would say when needing this skill; "promotable eval scenario metadata" and "Fixture skill" are internal technical jargon, matching anchor 1 ('No natural keywords; only technical jargon', e.g. 'Handles document object model manipulation'). It cannot be score 2 because even the generic natural phrases of that anchor ('Works with files') are absent.

Distinctiveness Conflict Risk

The niche (Skills SDK scenario-quality fixtures) is somewhat distinct, but with no actions or triggers the description could overlap with other test/fixture/eval skills, matching anchor 3 ('Somewhat specific but could still overlap with similar skills'). It is below score 4 because 'Works with PDF and Word document files' distinguishes via concrete artifacts, whereas nothing here differentiates it at trigger time.
