What it does

Centrifugo is an agent skill from pedronauck/skills. Centrifugo real-time messaging server expert for WebSocket PUB/SUB, channel management, JWT authentication, event proxying, and horizontal scaling with Redis/NATS. Use when: centrifugo, centrifugal, real-time messaging, websocket pubsub, channel subscriptions, real-time notifications, live updates, presence, history recovery, server-sent events integration, real-time transport layer. Do not use for: general WebSocket programming without Centrifugo, Socket.IO, Pusher SDK, or other real-time frameworks.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/authentication.md`, `references/channels.md` and `references/client-sdk.md`).

It sits in Backend & APIs, covering Realtime and WebSockets, Authentication and Event-driven systems. It works with Redis. The repository describes itself as: My personal favorite skills.

What it can do on your machine

Read from SKILL.md and the folder at commit 0422940. 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
Shell commands in SKILL.md call:
- curl
- docker
- npm
- bun
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, docker and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- API_KEY
- HMAC_SECRET
- JWT_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Centrifugo loads about 3.1k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 964 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~129
When it runs · the whole SKILL.md, loaded when a task matches: ~3.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~13k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 964 words (~3,091 tokens).

“Centrifugo is a self-hosted, language-agnostic real-time messaging server. It handles persistent connections (WebSocket, SSE, HTTP-streaming, WebTransport, GRPC) and broadcasts messages via a channel-based PUB/SUB model. The application backend publishes to channels via Server API; Centrifugo delivers to online subscribers instantly.”
