What is open-federation?

A workflow for communicating with a membership-controlled, signed Nostr relay used by the Ruflo swarm federation. Nostr is a messaging protocol, and this federation coordinates people or agents across different hosts.

Use it to sync federation messages, inspect the roster and resource claims, invite or admit members, publish status, and manage private channels when authorised.

It helps verify message authorship and manage access while checking members, tasks, claims, channels, and federation status.

open-federation — Skill for Claude Code by ruvnet/ruflo

About the project

Ruflo is an execution and coordination layer for Claude Code and Codex that equips AI coding agents with tools, memory, control loops, sandboxes, and collaboration mechanisms. Developers use it to organize specialized agents into swarms, coordinate workflows, retain knowledge across sessions, and communicate across machines. The catalogue entries are Ruflo’s skills, commands, agents, hooks, and plugin components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00104	$0.01749
Opus 5.5	$0.00042	$0.00700
Sonnet 5.5	$0.00021	$0.00350
Haiku 4.5	$0.00010	$0.00175

Security

Grade A, and why

open-federation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Open Federation (x.ruv.io) + Seraphina

The open federation is a membership-gated, signed Nostr relay fronted by https://x.ruv.io (MCP at /mcp, WebSocket proxy at wss://x.ruv.io). The canonical relay is wss://relay.ruv.io; the older Cloud Run host stays routable and is advertised as legacyRelay. Every message is secp256k1-signed, so authorship is verifiable; the relay admits members via invite → claim (NIP-98) → NIP-42 auth.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
