What problem does it solve? Applying generic Redis tutorials, vendor quickstarts, or cloud-first guidance to a governed infrastructure build often conflicts with established architecture decisions. This Skill keeps Redis work on HX-9 aligned with HX authority order, native systemd deployment standards, and the official smoke-test validation chain. ## Core Features & Use Cases - Authority-ordered Redis guidance: Reconciles official Redis documentation and the reviewed redis/agent-skills repository against HX control documents, classifying every recommendation as ACCEPT, ADAPT, REFERENCE_ONLY, REJECT_FOR_HX, or OWNER_DECISION_REQUIRED. - HX-9 deployment boundary enforcement: Covers native Ubuntu/systemd installation, shared-host memory sizing with PostgreSQL, persistence, eviction, key/TTL modeling, Search/vector/RAG, Streams, and the Redis MCP companion without allowing containers or cluster topologies by default. - Validation discipline: Enforces the B3 Redis core and B4 Redis MCP smoke-test proof chain, forbidding unexecuted PASS claims. - Use Case: When planning the HX-9 Redis build, an agent loads this Skill to verify the current upstream Redis release, classify upstream clustering or TLS advice against HX decisions, and confirm exactly which smoke tests prove the deployment. ## Quick Start Ask the agent to plan the HX-9 Redis installation and validation steps using the HX Redis Advisor before running any commands.
