Generates Cucumber BDD tests with Gherkin feature files and step definitions in Java, JavaScript, or Ruby.

  • User mentions Cucumber

What it does

Cucumber Skill is an agent skill from sickn33/agentic-awesome-skills. Generates Cucumber BDD tests with Gherkin feature files and step definitions in Java, JavaScript, or Ruby. Use when user mentions "Cucumber", "Gherkin", "Feature/Scenario", "Given/When/Then", "BDD".

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Java, JavaScript and Ruby. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • User mentions Cucumber
  • Feature/Scenario
  • Given/When/Then

Example prompts

  • “Cucumber”
  • “Gherkin”
  • “Feature/Scenario”
  • “/cucumber-skill”

Requirements

  • Node.js
  • A credential in LT_ACCESS_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit ec02547. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • mvn
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • hub.lambdatest.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • LT_ACCESS_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cucumber Skill loads about 1.8k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 259 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Core Patterns

Feature File (Gherkin)
gherkin
Feature: User Login
  As a registered user
  I want to log into the application
  So that I can access my dashboard

  Background:
    Given I am on the login page

  Scenario: Successful login
    When I enter "user@test.com" in the email field
    And I enter "password123" in the password field
    And I click the login button
    Then I should be redirected to the dashboard
    And I should see "Welcome" on the page

  Scenario: Invalid credentials
    When I enter "wrong@test.com" in the email field
    And I enter "wrongpass" in the password field
    And I click the login button
    Then I should see an error message "Invalid credentials"

  Scenario Outline: Login with various users
    When I enter "<email>" in the email field
    And I enter "<password>" in the password field
    And I click the login button
    Then I should see "<result>"

    Examples:
      | email           | password    | result     |
      | admin@test.com  | admin123    | Dashboard  |
      | user@test.com   | password    | Dashboard  |
      | bad@test.com    | wrong       | Error      |
Step Definitions — Java
java
import io.cucumber.java.en.*;
import static org.junit.jupiter.api.Assertions.*;

public class LoginSteps {
    private LoginPage loginPage;
    private DashboardPage dashboardPage;

    @Given("I am on the login page")
    public void iAmOnTheLoginPage() {
        loginPage = new LoginPage(driver);
        loginPage.navigate();
    }

    @When("I enter {string} in the email field")
    public void iEnterEmail(String email) {
        loginPage.enterEmail(email);
    }

    @When("I enter {string} in the password field")
    public void iEnterPassword(String password) {
        loginPage.enterPassword(password);
    }

    @When("I click the login button")
    public void iClickLogin() {
        dashboardPage = loginPage.clickLogin();
    }

    @Then("I should be redirected to the dashboard")
    public void iShouldBeOnDashboard() {
        assertTrue(driver.getCurrentUrl().contains("/dashboard"));
    }

    @Then("I should see {string} on the page")
    public void iShouldSeeText(String text) {
        assertTrue(dashboardPage.getPageSource().contains(text));
    }
}
Step Definitions — JavaScript
javascript
const { Given, When, Then } = require('@cucumber/cucumber');
const { expect } = require('chai');

Given('I am on the login page', async function() {
  await this.page.goto('/login');
});

When('I enter {string} in the email field', async function(email) {
  await this.page.fill('#email', email);
});

When('I click the login button', async function() {
  await this.page.click('button[type="submit"]');
});

Then('I should see {string} on the page', async function(text) {
  const content = await this.page.textContent('body');
  expect(content).to.include(text);
});

Limitations

  • Use this skill only when the task clearly matches its upstream source and local project context.
  • Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
  • Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
