Gherkin/BDD expert for writing, reviewing, and refactoring Cucumber feature files and step definitions.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Gherkin Expert Skill

Expert guidance for writing, reviewing, and refactoring Gherkin feature files
and Cucumber step definitions following BDD best practices.

## Capabilities

- **Author** well-structured `.feature` files with proper Given/When/Then flow
- **Review** existing feature files for anti-patterns and readability issues
- **Refactor** imperative scenarios into declarative specifications
- **Design** step definitions with appropriate parameterization
- **Organize** feature files with tags, backgrounds, and scenario outlines

## Usage

Activate explicitly with `/gherkin` or automatically when working with `.feature`
files, BDD scenarios, or acceptance criteria.

## Style Guide

### Preferred: Declarative

```gherkin
Scenario: Registered user logs in
  Given a registered user "alice"
  When the user logs in with valid credentials
  Then the user should see the dashboard
```

### Avoid: Imperative

```gherkin
Scenario: Login
  Given I am on the login page
  When I type "alice" into the username field
  And I type "password123" into the password field
  And I click the "Login" button
  Then I should see the text "Dashboard"
```

## Anti-Pattern Checklist
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add rysweet/amplihack-rs/gherkin-expert@sha256:b42f37dd6efd0883

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
