Loads tasks/subtasks from PM team output and executes through implementation → devops → SRE → unit testing → fuzz testing → property testing → integration testing (write) → chaos testing (write) → review → validation gates (Gates 0-9), with state persistence and metrics collection. Gates 6-7 (integration/chaos) write and update test code per unit but only execute tests at end of cycle (deferred execution). Multi-tenant dual-mode is implemented during Gate 0 and verified at Gate 0.5G (no separate post-cycle step).
development163

development163
ring:dev-multi-tenant
Multi-tenant development cycle orchestrator following Ring Standards. Auto-detects the service stack (PostgreSQL, MongoDB, Redis, RabbitMQ, S3) and whether the service has targetServices declared, then executes a gate-based implementation using tenantId from JWT for database-per-tenant isolation via lib-commons v4 tenant-manager sub-packages (postgres.Manager, mongo.Manager). Uses event-driven tenant discovery (Redis Pub/Sub via EventListener, TenantCache, TenantLoader) instead of polling-based discovery. TenantMiddleware with WithPG/WithMB variadic options handles both single-module and multi-module services. For services with targetServices: includes mandatory M2M credential retrieval from AWS Secrets Manager via lib-commons v4 secretsmanager package (per-tenant authentication with target service APIs). MUST update lib-commons v4 first; lib-auth v2 depends on it. Both are required dependencies. Each gate dispatches ring:backend-engineer-golang with context and section references. The agent loads multi-tenant.md via WebFetch and has all code examples.

development163
ring:dev-service-discovery
Scans the current Go project and identifies the Service → Module → Resource hierarchy for tenant-manager registration. Detects service name and type, modules (via WithModule or component structure), resources per module (PostgreSQL, MongoDB, RabbitMQ), and database names for each resource. Redis is excluded (managed via key prefixing). Produces a visual HTML report for human decision-making. Additionally detects MongoDB index definitions (both in-code EnsureIndexes and scripts/mongodb/*.js files), generates index creation scripts for any gaps, and uploads them to S3 for use during dedicated tenant database provisioning. Also detects database names per module, cross-references them across modules to find shared databases, and flags them for single-provision in tenant-manager.
