What problem does it solve?

This Skill helps you prevent the most dangerous test failure: passing CI while production still breaks, by explicitly designing where each test tier must guard against specific production gaps.

Core Features & Use Cases

• Production Gap Inventory: Identifies dev/CI vs production differences across DB dialects, OS/container behavior, dependency installation, environment variables, timezone/locale, mocks vs real dependencies, serialization, and packaging.
• Failure Mode Enumeration & Tier Allocation: Converts gaps into concrete failure modes and maps each to the correct tier (unit/integration/e2e/smoke/packaging) to eliminate proxy confidence.
• PR Smoke Suite + Adversarial Regression Backlog: Produces a minimum parity smoke set for PR gating and a structured backlog of adversarial regression tests derived from past incidents.
• Packaging / Dependency Integrity Checklist: Ensures built artifacts (installs/imports/containers) truly match what production will run, not just what source tests execute.
