SKILL.md
NATS Mastery (Senior → Principal)
Operate
- Start from messaging semantics: ephemeral pub/sub, request/reply, durable streams, or control-plane signaling.
- Treat subject design, consumer semantics, retention, and topology as first-class architecture concerns.
- Prefer simple subject hierarchies and explicit delivery semantics.
- Design for debuggability and operator clarity before chasing messaging cleverness.
Default Standards
- Subject naming should encode bounded, meaningful routing intent.
- JetStream retention and ack behavior must match business semantics.
- Consumers must be idempotent where durability and replay matter.
- Multi-tenant usage needs policy before it needs scale.
- Observability should reveal lag, redelivery, and cluster health clearly.
