What is claude-swarm CLAUDE.md?

Repository instructions for Claude Swarm, a Ruby package that coordinates several Claude Code sessions as a development team. They document setup, testing, linting, and the main parts of the code.

Use them when setting up the repository, running its Minitest tests, applying RuboCop fixes, opening a development console, or building and releasing the Ruby package.

They give an agent consistent project rules and commands, reducing guesswork when changing or checking the package.

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	$0.00780	$0.00780
Opus 5.5	$0.00312	$0.00312
Sonnet 5.5	$0.00156	$0.00156
Haiku 4.5	$0.00078	$0.00078

Security

Grade A, and why

claude-swarm CLAUDE.md 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 2mo 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.

Overview

Claude Swarm is a Ruby gem that orchestrates multiple Claude Code instances as a collaborative AI development team. It enables running AI agents with specialized roles, tools, and directory contexts, communicating via MCP (Model Context Protocol).

Development Commands

Setup

bin/setup              # Install dependencies

Testing

rake test             # Run the Minitest test suite

Linting

rake rubocop -A       # Run RuboCop linter to auto fix problems

Development Console

bin/console           # Start IRB session with gem loaded

Build & Release

bundle exec rake install    # Install gem locally
bundle exec rake release    # Release gem to RubyGems.org

Default Task

rake                  # Runs both tests and RuboCop

Architecture

The gem is fully implemented with the following components:

Core Classes

ClaudeSwarm::CLI (lib/claude_swarm/cli.rb): Thor-based CLI that handles command parsing and orchestration
ClaudeSwarm::Configuration (lib/claude_swarm/configuration.rb): YAML parser and validator for swarm configurations
ClaudeSwarm::McpGenerator (lib/claude_swarm/mcp_generator.rb): Generates MCP JSON configurations for each instance
ClaudeSwarm::Orchestrator (lib/claude_swarm/orchestrator.rb): Launches the main Claude instance with proper configuration

Key Features

YAML Configuration: Define swarms with instances, connections, tools, and MCP servers
Inter-Instance Communication: Instances connect via MCP using claude mcp serve with -p flag
Tool Restrictions: Support for pattern-based tool restrictions (e.g., Bash(npm:*))
Multiple MCP Types: Supports both stdio and SSE MCP server types
Automatic MCP Generation: Creates .claude-swarm/ directory with MCP configs
Custom System Prompts: Each instance can have a custom prompt via --append-system-prompt

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.
