OpenCode Discussion Agent

An OpenCode plugin that enables collaborative discussion between multiple AI agents to explore topics and develop solutions together.

Overview

This plugin provides a discussion framework with:

• Discussion Host (primary agent): Orchestrates the discussion and coordinates analysts
• Analysts (subagents): Multiple specialists analyzing from different angles

The agents collaborate rather than debate - each brings their expertise to collectively deepen understanding and develop better solutions. All discussions are recorded for reference.

Features

• Custom tools for discussion management:
  • discussion-setup: Auto-configure agents and commands (run once after install)
  • discussion-start: Initialize a discussion session
  • discussion-record: Record each analyst's analysis
  • discussion-summary: Generate analysis report
• Flexible analyst roles - customize based on topic needs (technical, economic, risk, legal, etc.)
• Detailed logging with both summary and individual analyst records
• Consensus detection and configurable round limits
• Web search capabilities for real-time information

Quick Start

1. Install Plugin

Add to your opencode.json:

{
  "plugin": ["opencode-debate-agent"]
}

2. Restart OpenCode

Restart your OpenCode session.

3. Run Setup

Input this during AI init:

use discussion-setup to init discussion agents

This will automatically create:

• ~/.config/opencode/agents/discussion-host.md
• ~/.config/opencode/agents/analyst.md
• ~/.config/opencode/commands/discussion.md

4. Restart and Use

Restart OpenCode, then start a discussion:

/discussion 如何优化团队协作流程

Discussion Workflow

1. Host starts the discussion with a topic
2. Host assigns roles to analysts (e.g., Technical Expert, Economic Analyst, Risk Analyst)
3. Each Analyst:
   • Reviews previous discussions
   • Provides analysis from their perspective
   • Responds to other analysts' viewpoints
   • Records their analysis
4. Host summarizes consensus and disagreements
5. Final report generated

Logging Structure

discussion-logs/{topic}/
├── record.log           # Summary of all discussions
├── summarize.log        # Final analysis report
└── analyst-{name}.log  # Individual analyst's detailed records

Customizing Analysts

The host can assign any roles based on the topic. Examples:

| Topic Type | Suggested Analysts | |------------|------------------| | Technical decisions | Technical Lead, User Experience, Security Expert | | Business planning | Market Analyst, Financial Analyst, Operations Expert | | Policy making | Legal Advisor, Ethics Expert, Stakeholder Representative | | Project planning | Project Manager, Risk Analyst, Resource Planner |

Each analyst receives context including:

• Their assigned role and focus areas
• The discussion topic
• Access to previous discussion records
• Web search capabilities for research

Customizing Models

The default configuration does not specify models. You can customize by editing the agent files:
