redis SKILL.md skillA
redis from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when using Redis or any Redis-protocol store (Valkey, ElastiCache, Upstash, Dragonfly, Memorystore) as a cache, queue, rate limiter or distributed lock and it has to be CORRECT rather than merely connected — stampede-proof caching, locks that cannot release someone else's hold, race-free rate limits, and jobs that survive a worker crash. NOT durable SQL queues with SELECT FOR UPDATE SKIP LOCKED (that is `postgresdb`), NOT vector similarity search over embeddings (that is `vector-db`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Redis — cache, lock, rate limiter, queue done correctly Redis is four primitives wearing one server: a **cache**, a **distributed lock**, a **rate limiter**, and a **job queue**. Each has a correctness contract that has nothing to do with whether `SET` returns `OK`. You almost certainly already "have Redis working" — a value goes in, a value comes out. What you do not yet have is a cache that won't stampede your database, a lock that won't release someone else's hold, a rate limiter that survives concurrent requests, and a queue whose jobs aren't silently lost when a worker dies. This skill is engine- and pattern-level, **client-SDK-agnostic**: examples are `redis-cli` and Lua, so they hold across node-redis, ioredis, redis-py, go-redis, and Lettuce. Every pattern applies unchanged to Valkey and any Redis-protocol store, since Valkey is a BSD fork of Redis 7.2 and stays protocol-compatible. ## When to use / When NOT **Use when you are:** - Adding or reviewing a **cache**: TTL strategy, cache-aside vs write-through, key naming, stampede/thundering-herd prevention, negative caching, invalidation. …

How to install
mdr add ericrisco/rsc-harness/redis@sha256:39f62ff40c249b2bThe line at the top of this page pins the label git:20260729.086c7b3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
