Conciseness

The ~24-line body is lean: it never explains what infographics or AntV are, and every line is either a workflow step, a hard constraint, or a pointer to `references/prompt.md`. Not a 4 because there is no over-explanation to trim — every token earns its place.

Actionability

Concrete, executable instruction sequence: read `references/prompt.md` (a real file), extract 'title, desc, items, hierarchy, metrics', select from named template classes '(sequence/list/compare/hierarchy/chart)', and obey explicit hard constraints ('single `infographic` markdown code block', 'two-space indentation', 'key value', 'arrays use `-`'). Not a 5 because no inline example of the DSL syntax appears in the body — the actual format is fully delegated to the reference, leaving a small gap if the reference is skimmed.

Workflow Clarity

Clear numbered 1–5 sequence ending in a 'Preserve hard constraints in every output' checklist that functions as an implicit checkpoint. Not a 5 because there is no explicit validation/verify step (e.g., 're-check the output against the constraints before responding'), only the constraint list itself; not a 3 because the sequence is complete and unambiguous with checkpoints present as an explicit constraint checklist.

Progressive Disclosure

A short overview body pointing to a single one-level-deep reference, `references/prompt.md`, which exists and contains the promised syntax rules, templates, and constraints; the reference is clearly signaled in both Overview and Workflow. Guideline for well-organized short skills with a single real reference is met; no nesting, no buried references, nothing inlined that belongs elsewhere.

Specificity

Names the domain ('AntV Infographic syntax outputs') and several concrete actions: 'template selection, data structuring, theme', and producing '`infographic <template>` plain syntax'. Not a 5 because it stops short of comprehensively enumerating what generation entails (e.g., no mention of formatting/layout rules or output constraints) — minor gaps in coverage remain.

Completeness

Explicitly answers both: what — 'Generate AntV Infographic syntax outputs' with the parenthetical '(template selection, data structuring, theme)'; when — 'Use when asked to turn user content into the Infographic DSL ... or to output `infographic <template>` plain syntax', with concrete trigger phrases. Matches the anchor-5 pattern of what + explicit when with concrete triggers.

Trigger Term Quality

Good natural trigger phrases: 'turn user content into the Infographic DSL', 'infographic <template>', 'template selection, data structuring, theme'. Not a 5 because synonyms and common variations users might say (e.g., 'visual summary', 'data poster', 'AntV G2/Infographic variants') are missing; not a 3 because coverage of the domain's natural terms is solid rather than merely partial.

Distinctiveness Conflict Risk

'AntV Infographic syntax/DSL' is a clear niche with distinct, specific triggers unlikely to fire for unrelated skills. Not a 4 because the only conceivable overlap is with other AntV/chart syntax skills, which the '`infographic <template>`' trigger phrase already disambiguates.
