redis

90 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

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`).

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'redis' ] || [ -L ~/.agents/skills/'redis' ]; then echo 'A skill folder named redis already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ericrisco/rsc-harness' "$d" && git -C "$d" checkout --quiet 'f3765d35e91690c0c7e511447da6cd0176ab38e0' -- 'skills/redis' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/redis' ~/.agents/skills/'redis' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'redis' ~/.claude/skills/'redis' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
