multi-agent-shogun

Command your AI army like a feudal warlord.

Run 10 AI coding agents in parallel — Claude Code, OpenAI Codex, GitHub Copilot, Kimi Code, OpenCode, Cursor, Antigravity — orchestrated through a samurai-inspired hierarchy with zero coordination overhead.

Talk Coding, not Vibe Coding. Speak to your phone, AI executes.

Quick Start

Requirements: tmux, bash 4+, at least one of: Claude Code / Codex / Copilot / Kimi / OpenCode / Antigravity

git clone https://github.com/yohey-w/multi-agent-shogun
cd multi-agent-shogun
bash first_setup.sh                        # one-time setup: config, dependencies, MCP
source ~/.bashrc                           # reload PATH
claude --dangerously-skip-permissions      # first run only: OAuth + accept Bypass Permissions → /exit
bash shutsujin_departure.sh                # launch all agents

For full install steps (incl. Windows) and the first-30-minutes walkthrough, see 🚀 Quick Start and the basic usage section below.

Type a command in the Shogun pane:

"Build a REST API for user authentication"

Shogun delegates → Karo breaks it down → 7 Ashigaru execute in parallel. You watch the dashboard. That's it.

What is this?

multi-agent-shogun is a system that runs multiple AI coding CLI instances simultaneously, orchestrating them like a feudal Japanese army. Supports Claude Code, OpenAI Codex, GitHub Copilot, Kimi Code, OpenCode, Cursor, and Antigravity.

Why use it?

• One command spawns 7 AI workers + 1 strategist executing in parallel
• Zero wait time — give your next order while tasks run in the background
• AI remembers your preferences across sessions (Memory MCP)
• Real-time progress on a dashboard

Why Shogun?

Most multi-agent frameworks burn API tokens on coordination. Shogun doesn't.

What makes this different

Zero coordination overhead — Agents talk through YAML files on disk. The only API calls are for actual work, not orchestration. Run 8 agents and pay only for 8 agents' work.

Full transparency — Every agent runs in a visible tmux pane. Every instruction, report, and decision is a plain YAML file you can read, diff, and version-control. No black boxes.

Battle-tested hierarchy — The Shogun → Karo → Ashigaru chain of command prevents conflicts by design: clear ownership, dedicated files per agent, event-driven communication, no polling.

Why CLI (Not API)?

Most AI coding tools charge per token. Running 8 Opus-grade agents through the API costs $100+/hour. CLI subscriptions flip this:

"Use AI recklessly" — With flat-rate CLI subscriptions, deploy 8 agents without hesitation. The cost is the same whether they work 1 hour or 24 hours. No more choosing between "good enough" and "thorough" — just run more agents.

Multi-CLI Support

Shogun isn't locked to one vendor. The system supports 7 CLI tools, each with unique strengths:

OpenCode sessions load the agent-specific .opencode/agents/<agent_id>.md definition via --agent and keep automation resets on /new; model changes require a relaunch. Automation uses the repository-provided config/opencode-tui.json via OPENCODE_TUI_CONFIG, which disables app_exit and pins session_interrupt/input_clear to known bindings. Role boundaries are embedded in the generated agent frontmatter: Shogun can read queue/reports/* for oversight but cannot write them, Karo is limited to coordination files plus report aggregation, Ashigaru only touch their own task/report pair, and Gunshi reads ashigaru reports but only writes gunshi_report.yaml.

Antigravity sessions launch with agy --dangerously-skip-permissions. Shogun treats type: antigravity, type: agy, and legacy type: gemini as Antigravity. Authentication and default model selection stay in the host user's Antigravity CLI setup; settings.yaml may optionally pass a concrete model, but auto uses the host default or last-used model.

A unified instruction build system generates CLI-specific instruction files from shared templates:

instructions/
├── common/              # Shared rules (all CLIs)
├── cli_specific/        # CLI-specific tool descriptions

│   ├── copilot_tools.md # GitHub Copilot CLI tools & features
│   ├── opencode_tools.md # OpenCode tools, agent frontmatter, and permission model
│   └── cursor_tools.md  # Cursor Agent tools, skills, and session rules
└── roles/               # Role definitions (shogun, karo, ashigaru)
    ↓ build
CLAUDE.md / AGENTS.md / .github/copilot-instructions.md / .opencode/agents/*.md / .cursor/rules/*.md
  ← Generated per CLI

One source of truth, zero sync drift. Change a rule once, all CLIs get it.

Bottom-Up Skill Discovery

This is the feature no other framework has.

As Ashigaru execute tasks, they automatically identify reusable patterns and propose them as skill candidates. The Karo aggregates these proposals in dashboard.md, and you — the Lord — decide what gets promoted to a permanent skill.
