A command for setting up a Claude Flow swarm, meaning a configured group of coordinated work patterns. It lets you choose how the group is connected and how tasks are executed.

Use it to select a topology such as mesh, hierarchical, ring, or star; set a maximum number of agents; choose an execution strategy; and optionally enable automatic spawning, memory, or GitHub integration.

It provides a reusable setup for organising work across different project needs, such as research, development, or GitHub tasks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00000	$0.00481
Opus 5	$0.00000	$0.00241
Sonnet 5	$0.00000	$0.00096
Haiku 4.5	$0.00000	$0.00048

Security

Grade A, and why

swarm-init 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 9d 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.

This is a copy

100% identical to swarm-init — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

swarm init

Initialize a Claude Flow swarm with specified topology and configuration.

Usage

npx claude-flow swarm init [options]

Options

--topology, -t <type> - Swarm topology: mesh, hierarchical, ring, star (default: hierarchical)
--max-agents, -m <number> - Maximum number of agents (default: 8)
--strategy, -s <type> - Execution strategy: balanced, parallel, sequential (default: parallel)
--auto-spawn - Automatically spawn agents based on task complexity
--memory - Enable cross-session memory persistence
--github - Enable GitHub integration features

Examples

Basic initialization

npx claude-flow swarm init

Mesh topology for research

npx claude-flow swarm init --topology mesh --max-agents 5 --strategy balanced

Hierarchical for development

npx claude-flow swarm init --topology hierarchical --max-agents 10 --strategy parallel --auto-spawn

GitHub-focused swarm

npx claude-flow swarm init --topology star --github --memory

Topologies

Mesh

All agents connect to all others
Best for: Research, exploration, brainstorming
Communication: High overhead, maximum information sharing

Hierarchical

Tree structure with clear command chain
Best for: Development, structured tasks, large projects
Communication: Efficient, clear responsibilities

Ring

Agents connect in a circle
Best for: Pipeline processing, sequential workflows
Communication: Low overhead, ordered processing

Star

Central coordinator with satellite agents
Best for: Simple tasks, centralized control
Communication: Minimal overhead, clear coordination

Integration with Claude Code

Once initialized, use MCP tools in Claude Code:

mcp__claude-flow__swarm_init { topology: "hierarchical", maxAgents: 8 }

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.

swarm-init is a command published in the GitHub repository ruvnet/ruv-FANN (380 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 481 tokens. A static security scan graded it A with 0 findings. It is 100% identical to swarm-init, differing in 10 lines, and is treated as a copy.
