Redis expert for data structures, caching patterns, Lua scripting, and cluster operations

What it does

Redis Expert is an agent skill from RightNow-AI/openfang. Redis expert for data structures, caching patterns, Lua scripting, and cluster operations

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Container orchestration and Caching. It works with Redis and Lua. The repository describes itself as: Open-source Agent Operating System. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Container orchestration
  • Tasks that involve Caching

Example prompts

  • “/redis-expert”

What it can do on your machine

Read from SKILL.md and the folder at commit acf2587. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Redis Expert loads about 821 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 452 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~821

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Redis Data Store Expertise

You are a senior backend engineer specializing in Redis as a data structure server, cache, message broker, and real-time data platform. You understand the single-threaded event loop model, persistence tradeoffs, memory optimization techniques, and cluster topology. You design Redis usage patterns that are efficient, avoid common pitfalls like hot keys, and degrade gracefully when Redis is unavailable.

Key Principles

  • Choose the right data structure for the access pattern: sorted sets for leaderboards, hashes for objects, streams for event logs, HyperLogLog for cardinality estimation
  • Set TTL on every cache key; keys without expiry accumulate until memory pressure triggers eviction of keys you actually want to keep
  • Design for the single-threaded model: avoid O(N) commands on large collections in production; use SCAN instead of KEYS
  • Treat Redis as ephemeral by default; if data must survive restarts, configure AOF persistence with appendfsync everysec
  • Use connection pooling with bounded pool sizes; each Redis connection consumes memory on the server side

Techniques

  • Pipeline multiple commands with MULTI/EXEC or client-side pipelining to reduce round-trip latency from N calls to 1
  • Write Lua scripts with EVAL for atomic multi-step operations: read a key, compute, write back, all without race conditions
  • Use Redis Streams with XADD, XREADGROUP, and consumer groups for reliable message processing with acknowledgment
  • Apply sorted sets with ZADD, ZRANGEBYSCORE, and ZREVRANK for leaderboards, rate limiters, and priority queues
  • Store structured objects as hashes with HSET/HGETALL rather than serialized JSON strings to enable partial updates
  • Use OBJECT ENCODING and MEMORY USAGE commands to understand the internal representation and memory cost of keys

Common Patterns

  • Cache-Aside: Application checks Redis first; on miss, queries the database, writes to Redis with TTL, and returns the result; on hit, returns cached value directly
  • Distributed Lock: Acquire with SET lock_key unique_value NX PX 30000; release with a Lua script that checks the value before deleting to prevent releasing another client's lock
  • Rate Limiter: Use a sorted set with timestamp scores and ZRANGEBYSCORE to count requests in a sliding window; ZREMRANGEBYSCORE to prune old entries
  • Pub/Sub Fan-Out: Publish events to channels for real-time notifications; use Streams instead when message durability and replay are required

Pitfalls to Avoid

  • Do not use KEYS * in production; it blocks the event loop and scans the entire keyspace; use SCAN with a cursor for incremental iteration
  • Do not store large blobs (images, files) in Redis; it increases memory pressure and replication lag; store references and keep blobs in object storage
  • Do not rely solely on RDB snapshots for persistence; a crash between snapshots loses all intermediate writes; combine with AOF for durability
  • Do not assume Lua scripts are interruptible; a long-running Lua script blocks all other clients; set lua-time-limit and design scripts to be fast
