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

# Scenario Testing Plugin

## Overview

This plugin enforces end-to-end testing with real dependencies instead of mocks. It validates that features actually work by exercising real systems with real data.

## Skill Included

### scenario-testing

**Trigger keywords**: test, mock, validate, feature complete, integration test, end-to-end, e2e, testing

**When to use**:
- Writing tests for new features
- Validating that code actually works
- When tempted to use mocks
- Before declaring work complete
- After fixing bugs

**What it does**:
1. Enforces "NO FEATURE IS VALIDATED UNTIL A SCENARIO PASSES WITH REAL DEPENDENCIES"
2. Requires scenarios in `.scratch/` directory (gitignored)
3. Prohibits mocks - must use real dependencies (sandbox/test mode acceptable)
4. Ensures scenarios run independently (no ordering dependencies)
5. Extracts recurring patterns to `scenarios.jsonl` (committed)

**Definition of done**:
- Scenario in `.scratch/` passes with zero mocks
- Real dependencies exercised
- `.scratch/` remains gitignored
- Patterns extracted to `scenarios.jsonl`

## Core Principle

**The Iron Law**: "NO FEATURE IS VALIDATED UNTIL A SCENARIO PASSES WITH REAL DEPENDENCIES"

How to install

The exact contents, by fingerprint
mdr add 2389-research/scenario-testing/CLAUDE.md@sha256:620ac08eae41e3e9

The line at the top of this page pins the label git:20251205.389da2d, 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.
