Engineering rules for building an interactive (online) gaming platform that can pass a GLI-19 technical certification — server-authoritative game outcomes with no game logic on the client, one authoritative system clock, the records a gaming system must maintain (per-game play record, per-theme aggregates with…
Command
Review a change for GLI-19 violations it introduces.
Command
Assess a service against the GLI-19 code-shaped requirements.

Security-engineering rules for an interactive gaming platform under the GLI Gaming Security Framework (GLI-GSF-1) — the deep security-controls layer beneath GLI-19's technical-security appendix, owning the infrastructure and network security territory (DNS, firewalls, remote access, hardening, segmentation, IDS/IPS…
Command
Review a change for GLI-GSF security-control violations it introduces.
Command
Audit a service or its infra against the GLI-GSF security controls.

pytest async-first testing best practices — test layer structure, fixture design, async testing with pytest-asyncio, test data with factoryboy + faker, HTTP mocking with respx, time mocking with freezegun, property-based testing with hypothesis, DB transaction-rollback isolation, flush() pattern for chained fixtures.
Skill Claude CodeCodex
This skill captures production-tested defaults for pytest with async support, factory-driven test data, real-DB integration testing, and CI-friendly configuration. It assumes the test target is a Python backend (FastAPI, SQLAlchemy, async services). UI / Selenium / Playwright e2e patterns are out of scope.
