Conciseness

The Rules and Anti-patterns sections are dense with non-obvious, project-specific judgment ("A UI Then is scored by Jev against the accessibility tree"), but the Structure section's basic Gherkin skeleton (Feature/Background/Given/When/Then) largely restates syntax Claude already knows and could be trimmed. This matches anchor 4's minor instances of over-explanation rather than anchor 5's every-token-earns-its-place.

Actionability

The body provides complete, copy-adaptable Gherkin templates for both a plain scenario and a Scenario Outline with an Examples table, plus concrete good/bad pairs ("When the customer submits the order" — never "When I click \"#submit-btn\"") and a Fix column in the anti-patterns table. Guidance is fully executable and covers the common cases.

Workflow Clarity

This is not a destructive or batch operation, so no cap applies. The Coverage section defines the process ("Work from the list of use cases and edge cases, not from intuition"), includes an explicit feedback loop ("A case with no scenario is a gap to report, not a case to silently drop"), and ends with a validation checklist ("**Done when** every case maps to at least one scenario, each scenario has exactly one When and an observable Then").

Progressive Disclosure

The skill is self-contained (~50 non-blank lines) with no external references needed, and content is well-organized into clearly navigable sections (Structure, Rules, Anti-patterns, Coverage). Per the simple-skill exception, well-organized sections with no need for external references score 5.

Specificity

"Write BDD scenarios in Gherkin" names the domain plus one concrete action, matching the anchor for 1-2 concrete actions without comprehensive coverage. It does not list several actions, so it falls below anchor 4.

Completeness

"Write BDD scenarios in Gherkin" clearly answers what the skill does, and "Trigger: acceptance criteria, Given/When/Then, feature files, test scenarios" explicitly answers when with four concrete trigger phrases. This matches the anchor 5 example where both what and when are explicit with concrete triggers.

Trigger Term Quality

The triggers "acceptance criteria, Given/When/Then, feature files, test scenarios" are natural phrases a user would say in this domain, but common synonyms like "BDD", "behavior-driven", or "Cucumber" are missing, keeping it below anchor 5's comprehensive coverage.

Distinctiveness Conflict Risk

"Given/When/Then" and "feature files" are unmistakably Gherkin-specific, giving a clear niche, but broader triggers like "test scenarios" and "acceptance criteria" could also fire for general test-writing skills. That minor overlap with closely related skills matches anchor 4 rather than anchor 5's minimal conflict risk.
