Integrations & protocols

Auth flow testing: 6 skills (auth0-tests, keycloak-tests, mfa-flow-test-author, oauth-flow-test-author, okta-tests, session-management-test-author) and 1 agent (token-storage-security-critic). Anchored on OAuth 2.0 / RFC 7636 PKCE / RFC 9700 / OWASP ASVS V3.

Feature-flag platform testing + experimentation harness testing: SDK-specific tests for LaunchDarkly plus the OpenFeature umbrella (Unleash, Flagsmith, GrowthBook); the feature-flag test matrix reference; the experiment-sdk-testing umbrella (Statsig, Optimizely, Split.io, Amplitude Experiment, VWO); AB-test validity checklist; experiment-results interpreter (peeking + guardrail references); stale-flag detector with the removal runbook; flag-coverage-gap detector; sample-ratio-mismatch (SRM) detector. Distinct from qa-test-environment/feature-flag-test-harness (generic flag-aware test harness) and qa-shift-right/feature-flag-experiment-validator (validates production experiment results); this plugin scopes to platform-SDK testing, flag-lifecycle hygiene, and experimentation-harness integrity.

GraphQL server testing: introspection attack-surface reference, persisted-query strategy, per-framework testing (Apollo Server, GraphQL Yoga, Hasura, Mercurius, Pothos), and an N+1 query detector. Distinct from qa-contract-testing/graphql-schema-regression (contract drift detection); this plugin covers server/runtime + framework-specific patterns.

gRPC testing tooling: buf-CLI lint and breaking-build, ghz load testing, grpcurl CLI, grpc-mock servers, protobuf versioning strategy reference, gRPC streaming test patterns, and status-code mapping reference. Distinct from qa-realtime-protocols/grpc-streaming-tests (wire-level streaming semantics) and qa-contract-testing/protobuf-compat-checking (schema-level breaking detection); this plugin scopes to tooling, load, linting, and framework-level testing.

Notifications + messaging testing across email/SMS/push/webhooks: 7 skills (email-flow-test-author, in-app-notification-test-author, mailhog-testing, mailpit-testing, push-notification-test-author, sms-test-author, webhook-delivery-tester) and 1 agent (notification-delivery-critic).

Payment platform sandbox testing: Stripe test cards + webhooks, Adyen test mode, PayPal sandbox, Braintree test cards; 3DS test flow + PCI DSS scope + payment flow states references; refund + chargeback + webhook-replay builders. Distinct from qa-compliance/pci-dss-control-test-author (compliance / scope verification); this plugin is platform-specific sandbox testing + payment flow state matrices.

Real-time protocol testing: 7 skills (grpc-streaming-tests, mqtt-tests, server-sent-events-tests, sse-load-tests, stomp-amqp-tests, webhook-replay-tests, websocket-tests) and 1 agent (realtime-protocol-reviewer). Anchored on RFC 6455, WHATWG SSE, gRPC streaming, MQTT v5, and the Standard Webhooks signature scheme.
