An agent meta-harness for Claude Code and Codex.

Get started in one command

Run this in your project folder:

npx ruflo@latest init

Then open Claude Code in the same folder and give it a real task, for example:

Use a ruflo swarm to review this repo: find the riskiest module, write tests for it, and summarise what you changed. 

init adds ruflo's agents, hooks, memory and MCP server to the project, and Claude Code picks them up on its next start. Codex and other MCP clients work too: point them at npx -y ruflo@latest mcp start.

First useful task, step by step · User guide · Compare install paths

Other ways to install (Claude Code plugins only, MCP-only clients, terminal UI)

Claude Code plugins only. This route installs core tools, the visual console and runtime mods, with no files added to your project. It needs Claude Code 2.1.287 or later. Run inside Claude Code:

/plugin marketplace add ruvnet/ruflo /plugin install ruflo-core@ruflo /plugin install ruflo-console@ruflo /plugin install ruflo-mods@ruflo /reload-plugins /ruflo 

From a terminal, on Claude Code 2.1.292 or later: claude plugin install ruflo-core@ruflo --marketplace ruvnet/ruflo. Mods run with your account's permissions, so review their code before installing.

Codex or another MCP client, without project setup. Configure the commandnpx with the arguments["-y", "ruflo@latest", "mcp", "start"]. To set up a project interactively, run npx ruflo@latest init wizard.

Plain terminal. The console also runs on its own, without Claude Code: npx ruflo tui. Add --plain to print one frame for scripts. See the terminal UI guide.

Optional: ruOS Desktop

Connect ruOS to ChatGPT or Claude via MCP:

📖 RuFlo Explained — Build an AI Team That Plans, Remembers, Tests, and Improves A 14-chapter guide: from the basic idea to a first useful task, then memory, agent teams, plugins, cost and verification.

Agent = Model + Harness. The model writes; the harness gives it tools, memory, loops, sandboxes, and controls so it can actually work. Ruflo is the harness — the execution layer around Claude Code and Codex that adds 100+ specialized agents, coordinated swarms, self-learning memory, federated comms across machines, and enterprise security guardrails. So agents don't just run, they collaborate.

One npx ruflo init gives Claude Code a nervous system: agents self-organize into swarms, learn from every task, remember across sessions, and — with federation — securely talk to agents on other machines without leaking data. You keep writing code. Ruflo handles the coordination.

_{Conceptual learning loop. Local vector retrieval and contrastive updates can run without an LLM; embeddings and configured learning modules are still required. See the RuVector training integration and trajectory contrastive learning.}

Architecture in text

User → Ruflo (CLI/MCP) → Router → Swarm → Agents → Memory → LLM providers. Memory feeds useful experience back into routing. This is a conceptual flow, not a live execution trace.

New to Ruflo? You don't need to learn 406 MCP tools or 61 CLI commands. After init, just use Claude Code normally — the hooks system automatically routes tasks, learns from successful patterns, and coordinates agents in the background.

An origin you can inspect

Built by Reuven Cohen (rUv), originally as Claude Flow. The first commit, June 2, 2025, describes a code orchestration layer for recursive agent cycles: Claude writes, edits, tests and improves. The June 10 source snapshot adds orchestration, task scheduling, memory and terminal modules.

A harness is the workbench around the model: it organizes tasks, carries context between steps and helps check results. This establishes Ruflo's lineage, not a universal first across every Claude Code tool.See the illustrated explainer, exact commits and earlier ecosystem context.

Grok Build:npx ruflo init --grok writes the project host surface (.grok/, the team bus, and the operator guide) and nothing outside the project; add --dry-run to preview. Setup, the spawn_subagent contract, the optional status row, and what to re-check when Grok updates: the Grok operator guide.

📖 Background — where the name comes from

Claude Flow is now Ruflo — named by rUv, who loves Rust, flow states, and building things that feel inevitable. The "Ru" is the rUv. The "flo" is working until 3am. Underneath, powered by Cognitum.One agentic architecture, running a supercharged Rust-based AI engine, embeddings, memory, and plugin system.

Open animated demo · Theme Studio guide · Workflow demo

Your agent cockpit. Track workflows, agents, models, tokens and cost beside Claude Code. The 38 second animation shows Orbital and Theme Studio through actual renderer frames, including boot checks, six palettes, customization, saved themes, JSON import and resizing. This compact 3.84 MB SVG retains all 456 frames. Native host and AI provider execution are not demonstrated.

Inspect any run. Open agent logs and results, search, triage failures, replay and compare. Start with npx ruflo init, restart Claude Code, then /ruflo. Full console tour.

Let Claude drive. You set the limits. Enable Settings → Claude control to navigate and run console actions. Choose read, write, manage or full, with ask or auto approval. The current default is read + ask; raising the level is your choice. Actions above your permission level are refused, and network, spending and destructive actions require confirmation even in auto. Review the live action log or press Take back control to stop Claude control. Details.

One task: create a mission with Claude

Watch the recorded console session below. Claude creates a mission, opens the Learning and Security pages, and reports its actions in Overview.

1. Set the boundary. Install the console using the commands below, open /ruflo, then choose Settings → Claude control → write + ask.
2. Give a concrete request. Try: “Create a mission to add a dark mode toggle. Show me the mission and its status.”
3. Approve creation. Claude opens Missions and sets the goal. Confirm the pending create action in the console.
4. Verify the result. Check that Missions contains the goal and Overview records the action. Creating a mission does not mean the feature has been implemented.
5. Keep control.Take back control pauses Claude's console tools. A later call should be refused until you restore control.

What the recording demonstrates: a real Claude Haiku session with write + auto, mission creation, page navigation, a refused swarm stop, and control being taken back. The steps above use ask so you approve creation yourself. The linked workflow animation uses sample data, while the theme demo replays renderer frames. Neither is evidence of completed swarm work or memory recall.

Implementation and recorded test findings · Reproduction script

Install the mods from the ruflo marketplace (Claude Code 2.1.287 or later; mods run with your account's permissions and are not sandboxed, so read the code first):

/plugin marketplace add ruvnet/ruflo /plugin install ruflo-console@ruflo /plugin install ruflo-mods@ruflo /reload-plugins 

ruflo-console is the cockpit above, ruflo-mods routes prompts and enforces policy in-process, ruflo-swarm shows the swarm in a pane, and ruflo-ruos adds the ruOS status segment. Open /plugin to confirm they appear in the active mods line. Inside the console, /ruflo market is the Plugin Catalog: every ruflo plugin, mod and skill with what it ships, and buttons to install, enable, disable and update (each asks first).

Quick Start

There are two different install paths with very different surface areas. Pick based on what you need (#1744):

	Claude Code Plugin	CLI install (npx ruflo init)
What it gives you	Slash commands + a few skills + agent definitions per-plugin	Full Ruflo loop — 98 agents, 60+ commands, 30 skills, MCP server, hooks, daemon
Files in your workspace	Zero	.claude/, .claude-flow/, CLAUDE.md, helpers, settings
MCP server registered	Only if ruflo-core is installed (it ships its own .mcp.json) — most other plugins don't	Yes
Hooks installed	No	Yes
Best for	Try a single plugin's commands without committing to the full install	Production use — everything works as documented

Path A — Claude Code Plugins (lite, slash commands only)

# Add the marketplace /plugin marketplace add ruvnet/ruflo # Install core + any plugins you need /plugin install ruflo-core@ruflo /plugin install ruflo-swarm@ruflo /plugin install ruflo-rag-memory@ruflo /plugin install ruflo-neural-trader@ruflo

This adds slash commands and agent definitions. ruflo-core (installed above) does register its own MCP server on install — its tools are callable as mcp__plugin_ruflo-core_ruflo__* (e.g. mcp__plugin_ruflo-core_ruflo__memory_store), not the bare memory_store/swarm_init/agent_spawn names the CLI-track scaffold uses. Other plugins generally don't ship their own MCP server. For the full loop with the CLI-track tool names, use Path B below.

CLI Install

macOS / Linux / WSL / Git-Bash:

# One-line install (POSIX shells only — see Windows note below) curl -fsSL https://cdn.jsdelivr.net/gh/ruvnet/ruflo@main/scripts/install.sh | bash

All platforms (including native Windows PowerShell / cmd):

# Interactive setup wizard — runs identically on every platform npx ruflo@latest init wizard # Quick non-interactive init# npx ruflo@latest init# Or install globally npm install -g ruflo@latest

💡 Windows users: the curl ... | bash form needs a POSIX shell (Git-Bash, WSL, MSYS). The npx ruflo@latest init wizard line works natively in PowerShell and cmd. If you hit an 'bash' is not recognized error, use the npx line instead — both end up running the same init flow.

MCP Server

# Add Ruflo as an MCP server in Claude Code claude mcp add claude-flow -- npx ruflo@latest mcp start

Learning from experience

Useful trajectories and task feedback can inform future work. Results depend on the configured memory, learning components and quality of feedback. Learning plugin.

Agent Federation — Slack for Agents

Slack gave teams channels. Federation gives agents the same thing — shared workspaces across trust boundaries, where agents on different machines, orgs, or cloud regions can discover each other, prove who they are, and collaborate on tasks.

The difference: some channels are trusted, some aren't. @claude-flow/plugin-agent-federation handles that automatically. Your agents join a federation, get verified via mTLS + ed25519, and start exchanging work — with PII stripped before anything leaves your node and every message auditable. Untrusted agents can still participate at lower privilege: they see discovery info, not your memory. As they prove reliable, trust upgrades. If they misbehave, they get downgraded instantly — no human in the loop required.

You don't configure handshakes or manage certificates. You federation init, federation join, and your agents start talking. The protocol handles identity, the PII pipeline handles data safety, and the audit trail handles compliance.

📘 Full user guide:docs/federation/ — setup, MCP tools, trust levels, circuit breaker, and the (opt-in) WireGuard mesh layer that ties packet-layer reachability to federation trust. ADR-111 deep-dive at docs/federation/phase7-mesh-bringup.md.

Federation capabilities

	Capability	How it works
🔒	Zero-trust federation	Remote agents start untrusted. Identity proven via mTLS + ed25519 challenge-response. No API keys, no shared secrets.
🛡️	PII-gated data flow	14-type detection pipeline scans every outbound message. Per-trust-level policies: BLOCK, REDACT, HASH, or PASS. Adaptive calibration reduces false positives.
📊	Behavioral trust scoring	Formula (0.4×success + 0.2×uptime + 0.2×threat + 0.2×integrity) continuously evaluates peers. Upgrades require history; downgrades are instant.
📋	Compliance built-in	HIPAA, SOC2, GDPR audit trails as compliance modes. Every federation event produces a structured record searchable via HNSW.
🤝	9 MCP tools + 10 CLI commands	Full lifecycle: federation_init, federation_send, federation_trust, federation_audit, and more.

Example: two teams sharing fraud signals without sharing customer data

# Team A: initialize federation and generate keypair npx claude-flow@latest federation init # Team A: join Team B's federation endpoint npx claude-flow@latest federation join wss://team-b.example.com:8443 # Team A: send a task — PII is stripped automatically before it leaves npx claude-flow@latest federation send --to team-b --type task-request \ --message "Analyze transaction patterns for account anomalies"# Team A: check peer trust levels and session health npx claude-flow@latest federation status

See issue #1669 for the complete architecture, trust model, and implementation roadmap.

# Claude Code plugin /plugin install ruflo-federation@ruflo # Or via CLI npx claude-flow@latest plugins install @claude-flow/plugin-agent-federation
