Conciseness

The body is lean overall with no 'what is BDD' padding, but the async guidance is repeated three times ('Check that step definitions return or await promises. Steps that don't wait for async operations will complete before actions finish' followed by 'Pattern: Ensure `async` functions use `await` for all asynchronous calls'), and the troubleshooting section repeats the exact dry-run command already shown. These are minor, trimmable instances of over-explanation rather than pervasive padding.

Actionability

Five copy-paste-ready bash commands each include expected results, and anti-patterns give concrete BAD/GOOD Gherkin examples. Minor gaps keep it below fully executable: no step-definition code sample despite 'implementing step definitions' being a core workflow step, and the 'Evaluate this skill quality' command references a script path ('skills/agentic-harness/skill-quality-auditor/scripts/evaluate.sh') that does not exist in this bundle.

Workflow Clarity

The 'Deterministic Workflow' is a clear 5-step sequence with explicit validation checkpoints and feedback loops — 'If scenarios fail due to incorrect business logic, loop back to step 2' and 'loop back to step 3 to fix implementation' — plus error recovery via 'npx cucumber-js --dry-run'. This matches the top anchor: explicit validation steps, feedback loops for error recovery.

Progressive Disclosure

The body is a well-organized overview with a one-level-deep References section, and all five cited reference files exist in the bundle. Minor organization gaps: 'principles-living-documentation.md' and 'principles-ubiquitous-language.md' are present but never referenced from the body (orphaned), and one command points to a nonexistent script.

Specificity

The description lists multiple concrete actions — 'Write and maintain Behavior-Driven Development tests with Gherkin and Cucumber', 'defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues' — covering authoring and diagnosis comprehensively with no coverage gaps.

Completeness

It explicitly answers both 'what' ('Write and maintain Behavior-Driven Development tests with Gherkin and Cucumber') and 'when' ('Use when defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues') with concrete trigger phrases.

Trigger Term Quality

The keyword list — 'bdd, gherkin, cucumber, given when then, feature files, step definitions, acceptance criteria, three amigos, example mapping' — comprehensively covers the natural terms and synonyms users would say, including the colloquial 'given when then' phrasing.

Distinctiveness Conflict Risk

The BDD/Gherkin/Cucumber niche is clearly defined with tool-specific triggers (cucumber, gherkin, three amigos, example mapping), making conflicts with general testing or TDD skills unlikely.
