pantheon-ai/bdd-testing

Write and maintain Behavior-Driven Development tests with Gherkin and Cucumber. Use when defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues. Keywords: bdd, gherkin, cucumber, given when then, feature files, step definitions, acceptance criteria, three amigos, example mapping.

Content

92%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is concise, highly actionable, and has an excellent validated workflow with error-recovery loops. The main weakness is progressive disclosure: the skill points to five reference files that are not bundled, leaving dead links.

Suggestions

Create the five referenced files under references/ (gherkin-syntax.md, principles-core-philosophy.md, principles-three-amigos.md, principles-example-mapping.md, cucumber-setup.md) so the disclosure actually resolves, or remove the References section.

Remove the duplication between the Deterministic Workflow 'Error recovery' bullets and the 'Troubleshoot common Cucumber failures' section (dry-run for missing steps and async-timing guidance appear in both).

If references/ is not intended to ship, inline the minimal essential Gherkin syntax primer so the skill is self-contained.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it does not explain what BDD/Gherkin is and gives direct commands with expected results. A score below 3 would require more padding than is present, though the dry-run and async-timing guidance is lightly duplicated across the workflow and troubleshoot sections.

3 / 3

Actionability

Quick Commands are fully executable and copy-paste ready ('npx cucumber-js features', 'npx cucumber-js --dry-run features', '--tags', '--format json:...'), with concrete GOOD/BAD Gherkin examples and stated expected results.

3 / 3

Workflow Clarity

The Deterministic Workflow is a clear numbered sequence with explicit 'Validation checkpoint' feedback loops (loop back to step 2/3) and 'Error recovery' steps, matching the top anchor for validation + error recovery.

3 / 3

Progressive Disclosure

The References section is well-signaled and one-level-deep, but the five referenced files (principles-core-philosophy.md, gherkin-syntax.md, etc.) do not exist — no references/ directory is present — so the navigation promise is broken and the disclosed detail is unreachable.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, complete, and well-triggered with an explicit 'Use when' clause and a strong keyword list. It uses an imperative voice consistent with the rubric's good examples, so no voice penalty applies.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues' — matching the anchor for several specific concrete actions.

3 / 3

Completeness

Clearly answers both 'what' (Write and maintain BDD tests with Gherkin and Cucumber) and 'when' via an explicit 'Use when...' clause, satisfying the top anchor for both.

3 / 3

Trigger Term Quality

An explicit 'Keywords:' block gives good natural-term coverage users would say: bdd, gherkin, cucumber, given when then, feature files, step definitions, acceptance criteria, three amigos, example mapping.

3 / 3

Distinctiveness Conflict Risk

A clear BDD/Cucumber/Gherkin niche with distinct, domain-specific triggers makes it unlikely to fire for the wrong skill.
