feature is a cursor rule for Cursor from m3au/playwright-bdd-cursor-template. It costs 0 tokens per session (369 once invoked), scanned A, original, MIT.

A set of standards for Gherkin feature files, the plain-text files used to describe behavior in behavior-driven development, or BDD.

In plain words
What is it for?
Use it when writing Feature, Scenario, Given, When, and Then steps, including data-driven scenarios and reusable actions.
Why use it?
It keeps scenarios consistent, readable, and connected to automated step definitions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Feature File Standards

Structure

  • Start with Feature: followed by a descriptive title
  • Include user story format: "As a... I want... So that..."
  • Use Scenario: for individual test cases
  • Use Scenario Outline: with Examples: for data-driven tests
  • Use @skip tag for disabled scenarios (prefer commenting them out if long-term disabled)

Step Definitions

  • A: start steps with "I" (e.g., "I navigate", "I click", "I see")
  • N: use "should" in step text (e.g., "I should see", use "I see" instead)
  • N: use "and" or "or" in the middle of a step description (e.g., "I see popup closed and connector selected")
  • Use Given for setup/preconditions (e.g., "Given I navigate to the page")
  • Use When for user actions (e.g., "When I click on button")
  • Use Then for assertions/outcomes (e.g., "Then I see the result")
  • Use And keyword only to continue steps of the same type, never in step text
  • Keep steps concise and action-oriented
  • Each step should verify or perform ONE thing only
  • Reference step definitions implemented in POMs via decorators

Best Practices

  • One scenario per specific behavior
  • Steps should be reusable across scenarios
  • Use descriptive step text that clearly states intent
  • Avoid implementation details in step text
  • Keep scenarios independent and testable in isolation
  • Use tags (@skip, etc.) for test organization

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
