Use when adding, changing, reviewing, testing, synchronizing, or read-only ingesting user-visible behavior with BDD, Gherkin, Given/When/Then scenarios, .feature files, acceptance criteria, knowledge catalogs, or bug-fix behavior specs.

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 BDD

Use this Skill for user-visible behavior. In strict tasks, new or changed behavior that a user, administrator, API client, CLI user, integration system, exported file consumer, notification recipient, or permission/error-state observer can see must have a persistent BDD scenario before implementation is completed. In default/lite tasks, apply this Skill when user-visible behavior, project rules, risk, or explicit delivery requirements call for persistent behavior evidence.

BDD does not replace PRD, DDD, TDD, project validation, or task workflows. It turns confirmed acceptance behavior into executable examples. PRD explains intent and scope, DDD stabilizes vocabulary and boundaries, BDD specifies observable behavior, and TDD turns the scenario into red tests and green implementation.

## When To Use

Use this Skill when:

- The user asks for BDD, Gherkin, Given/When/Then, `.feature`, scenarios, acceptance criteria, or behavior specs.
- A task adds or changes UI, API, CLI, exported files, notifications, permissions, errors, status changes, or externally observable integration behavior.
- A user-visible bug is being fixed.

How to install

The exact contents, by fingerprint
mdr add kunolu/640-skills/gherkin-bdd@sha256:d71995edd66b1a02

The line at the top of this page pins the label git:20260920.f9bbb90, 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.
