debate

debate v2

Get a second (and third, and fourth) opinion on your implementation plan before you write a line of code. debate sends your plan to multiple AI reviewers in parallel, synthesizes their feedback, has them argue out contradictions, and produces a consensus verdict.

v2 is a ground-up rewrite. Everything now runs through acpx — a single unified CLI that talks to any coding agent. No more managing individual CLIs, session files, or API keys per provider. One config, any combination of models.

Quick Start

# 1. Install the plugin
/plugin marketplace add STRML/cc-debate
/plugin install debate@cc-debate

# 2. Install acpx
npm install -g acpx@latest

# 3. Configure your review panel (interactive)
/debate:acpx-setup

# 4. Run a review
/debate:all

Restart Claude Code after installing the plugin.

  VERDICT: APPROVED — unanimous after 2 rounds

What you need

Required:

• acpx — npm install -g acpx@latest
• jq — brew install jq / apt install jq
• The agent CLIs for whatever reviewers you want (see Supported Agents below)

Optional:

• opencode — only needed for OpenRouter model access (DeepSeek, Mercury, Kimi, etc.) or LiteLLM proxy access (local models, self-hosted, etc.)

Supported Agents

These are the reviewer backends you can use. Mix and match — pick 2-4 for a useful review panel.

Built-in acpx agents

These have native Agent Client Protocol support. Install the CLI, and acpx handles the rest.

Agent name	Model	Install
codex	OpenAI Codex	npm install -g @openai/codex + OPENAI_API_KEY
gemini	Google Gemini 2.x/3.x	npm install -g @google/gemini-cli + gemini auth + GEMINI_API_KEY ¹
claude	Claude (Opus/Sonnet)	Already installed — you're running it now
kimi	Kimi (Moonshot AI)	See Kimi CLI docs
kiro	Kiro (AWS)	See Kiro docs
qwen	Qwen Code	See Qwen Code docs
cursor	Cursor	Install Cursor IDE
copilot	GitHub Copilot	gh extension install github/gh-copilot
opencode	OpenCode (default model)	npm install -g opencode-ai
kilocode	Kilocode	npx @kilocode/cli
droid	Factory Droid	See acpx docs
iflow	iFlow	See acpx docs
pi	Pi Coding Agent	See acpx docs
openclaw	OpenClaw	See acpx docs

¹ Gemini note: The Gemini CLI's stored OAuth works for direct CLI use but not for acpx's non-interactive subprocess mode. You need a separate API key. Get one free at aistudio.google.com/apikey, then add it to ~/.claude/settings.json:

"env": { "GEMINI_API_KEY": "AIza..." }

Antigravity CLI transition (June 18, 2026): Google is migrating Google One and free-tier Gemini CLI users to the new Antigravity CLI. The GEMINI_API_KEY path used by this plugin is unaffected — AI Studio API keys bill against AI Studio quota, not Google One OAuth tiers, so the gemini reviewer continues to work. Paid Gemini Code Assist Standard/Enterprise users also keep the gemini CLI as-is. A dedicated antigravity reviewer will be added once acpx ships native ACP support for it.

Claude note: Using claude as a reviewer means Claude reviewing its own plan — useful for a fresh-context skeptical read, but not truly independent. For independent perspectives, use non-Claude agents. invoke-acpx.sh automatically handles the nested-session guard (CLAUDECODE) required to run Claude as a subprocess.
