Conciseness

Largely lean with no concept padding (it never explains what Gherkin or BDD is), but a few tokens could be trimmed: the As-a/I-want/So-that to Feature-header mapping is basic Gherkin knowledge, and the bottom References section duplicates links already cited inline in the body sections.

Actionability

For an instruction-only skill the guidance is fully actionable: a routing table over four input shapes, numbered procedures, a step-classification taxonomy, named R1-R5 rewrite rules, worked Gherkin examples, a concrete output template, and an anti-patterns table with fixes.

Workflow Clarity

Each input shape has a clearly sequenced procedure with explicit validation checkpoints ("at most one When per scenario; lint; specificity preserved", observability validation of every Then, side-by-side review table) and a flag-and-ask feedback loop for implicit preconditions.

Progressive Disclosure

The body is a well-organized overview that moves full worked examples and rule catalogs into three real, one-level-deep reference files, each clearly signaled inline with a description of its contents (verified: all three referenced files exist and contain no nested references).

Specificity

Lists multiple concrete actions — "Maps criteria to scenarios", "finds Scenario Outlines and Background", "reuses existing steps and flags hidden preconditions" — plus an explicit boundary ("Writes Gherkin only, not step code"), with no coverage gaps for the skill's scope.

Completeness

Explicitly answers both: an explicit "Use whenever..." trigger clause listing concrete input artifacts, and a clear statement of what the skill does, including what it deliberately does not do.

Trigger Term Quality

Natural trigger terms cover all input artifacts ("user stories", "acceptance criteria", "manual test steps", "spec section") and the output ("Gherkin", ".feature files"), but common user phrasings like "BDD", "Cucumber", or "behavior scenarios" are missing, so it falls just short of comprehensive.

Distinctiveness Conflict Risk

Clear niche (requirements text to Gherkin .feature files) with distinct triggers, and the negative boundary "Writes Gherkin only, not step code" explicitly separates it from step-definition and runner skills.
