Recommendation-systems-engineering team — the RECSYS layer that turns interaction data into ranked recommendations. agents (recsys-architect, recsys-implementation-engineer) covering approach selection (popularity baseline, collaborative filtering, content-based, hybrid, two-tower/embedding retrieval, sequential), the candidate-generation → ranking → re-ranking pipeline, cold-start (new user/new item), offline evaluation (recall@k, nDCG, MAP, coverage/diversity) AND online A/B, feature stores with train/serve parity, low-latency serving, and feedback-loop/position bias. skills, Mermaid-backed knowledge docs, templates. Seams: training infra → ml-engineering; keyword/semantic search → search-relevance-engineering; A/B + stats → experimentation-growth-engineering + applied-statistics. House line: baseline before a neural net; offline wins must survive an online A/B. Requires ravenclaude-core@>=0.7.0.

Serverless engineering team — agents for building on serverless the provider-neutral way. serverless-architect owns the design side: event-driven decomposition, FaaS-vs-containers-vs-managed-services and when serverless is the WRONG choice, sync/async, orchestration-vs-choreography, event contracts, the dual-write/outbox problem, and serverless-friendly storage. serverless-runtime-and-ops-engineer owns the runtime side: cold starts, concurrency & throttling, idempotency & exactly-once-effect, DLQs & poison messages, retries, per-invocation cost & the scale crossover, tracing in ephemeral runtimes, and local emulation. skills, a knowledge bank (a Mermaid decision tree + a dated 2026 patterns reference), templates. Provider-neutral PATTERNS only — distinct from aws-cloud/gcp-cloud/azure-cloud (provider IaC/specifics), data-streaming-engineering (Kafka/Kinesis), devops-cicd (deploy pipeline), backend-engineering (the serverful alternative), observability-sre (SLOs). Requires ravenclaude-core@>=0.7.0.
