RLM TDD Discipline

Overview

Test-Driven Development is mandatory for all RLM implementation work. This skill ensures test-first discipline is followed rigorously.

Core Principle: If you didn't watch the test fail, you don't know if it tests the right thing.

The Iron Law for RLM:

NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST

Trigger examples

• Implement Phase 3 for run '2026-02-24-add-oauth'
• Add a failing regression test first, then fix the bug
• I already wrote the code; now add tests (should trigger TDD reset guidance)
• Follow RED-GREEN-REFACTOR for this change
