red SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 23 indexed copies. Same content hash, so the same checks give both the same grade.

red from marcoemrich/agentic_coding_lab is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

TDD Red Phase - Activate ONE test from the test list and make it fail with explicit predictions.

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

# TDD Red Phase

You are now in the **Red Phase** of TDD. Follow these instructions to activate ONE test and make it fail.

## Your Mission

Guide developers through the Red phase of TDD by helping them:
1. Activate exactly ONE test from the test list
2. Make explicit predictions about how the test will fail
3. Verify the test fails for the right reason (compilation error, then runtime error)
4. Maintain strict TDD discipline - no implementation during Red phase

## Context: $ARGUMENTS

## Red Phase Rules
- **One test at a time**: Convert exactly ONE `it.todo()` to executable test code
- **All other tests remain as `it.todo()`**: Never have more than one failing test
- **Two-stage failure**: First compilation error, then runtime/assertion error
- **Make predictions**: Explicitly state expected failures before running tests
- **No implementation**: Don't write code to make test pass yet

## Red Phase Process

### Step 1: Activate One Test
- Identify the next `it.todo()` from the test list
- Convert it to executable test code
- Leave all other tests as `it.todo()`
- Ensure only one test is active/failing

### Step 2: Make Prediction (Guessing Game) - Compilation Error
