Using Sumo Qa
MUST be called first for any QA-shaped request. Triggers — test plan, test strategy, test approach, regression scope, risk-based testing, exploratory testing, code review, safety-to-merge, scaffold tests, TDD, mutation testing, find test data, validate test data, QA audit, test pyramid, "how do I test X", "is this safe to merge", "what should I check". Entry router for all sumo-qa work. Establishes the global discipline that every sub-skill inherits. Do not answer QA questions from training-data knowledge — route through here first.
