modbender Agent Debate Skill
Spawn multiple sub-agents to debate approaches and converge on the best solution.
Overview
Uses parallel sub-agents with file-based coordination to simulate adversarial debate. Each agent investigates independently, writes findings, then a synthesis agent reviews all positions and picks the winner.
Pattern: Competing Hypotheses
Best for: architecture decisions, debugging, strategy, trade analysis
How It Works
- Lead defines the question and spawns 2-4 debate agents
- Each agent writes their position to
plans/debate-{id}/agent-{n}.md - A synthesis agent reads all positions and produces a verdict
- Lead reviews and acts on the verdict
File Structure
plans/debate-{topic}/
├── question.md # The question being debated
├── agent-1.md # Agent 1's position
├── agent-2.md # Agent 2's position
├── agent-3.md # Agent 3's position (optional)
├── rebuttal-1.md # Agent 1's rebuttal (round 2)
├── rebuttal-2.md # Agent 2's rebuttal (round 2)
├── synthesis.md # Final synthesis and verdict
└── decision.md # Lead's final decision
Usage
Single Round (Fast)
3 agents, one round, synthesis. ~5 minutes.
1. Write question to plans/debate-{topic}/question.md
2. Spawn 3 agents simultaneously:
- Agent A: "Argue FOR approach X. Read plans/debate-{topic}/question.md. Write your position with evidence to plans/debate-{topic}/agent-1.md"
- Agent B: "Argue FOR approach Y. Read plans/debate-{topic}/question.md. Write your position with evidence to plans/debate-{topic}/agent-2.md"
- Agent C: "Argue FOR approach Z. Read plans/debate-{topic}/question.md. Write your position with evidence to plans/debate-{topic}/agent-3.md"
3. Wait for all to complete
4. Spawn synthesis agent:
"Read all positions in plans/debate-{topic}/. Score each on: feasibility (1-10), risk (1-10), speed (1-10), quality (1-10). Write verdict to plans/debate-{topic}/synthesis.md"
Two Round (Thorough)
3 agents, position + rebuttal, synthesis. ~10 minutes.
Round 1: Same as single round (positions)
Round 2: Each agent reads others' positions and writes rebuttals
- "Read all agent-*.md files. Write a rebuttal challenging the other positions. Save to rebuttal-{n}.md"
Round 3: Synthesis reads everything and decides
Red Team (Adversarial)
1 builder + 1 attacker. Best for security/robustness.
1. Builder: "Design/implement X. Write to plans/debate-{topic}/proposal.md"
2. Attacker: "Read proposal.md. Find every flaw, vulnerability, and edge case. Write to plans/debate-{topic}/attack.md"
3. Builder: "Read attack.md. Address each issue. Write to plans/debate-{topic}/defense.md"
4. Synthesis: "Score the final defense. Is it production-ready?"
Model Assignment
- Debate agents: Opus 4.6 (needs deep reasoning)
- Synthesis agent: Opus 4.6 (needs to weigh nuanced arguments)
- Simple positions: Sonnet 4.5 (if cost matters and topic is straightforward)
When To Use
✅ Architecture decisions with multiple valid approaches ✅ Debugging with unclear root cause ✅ Trading strategy evaluation ✅ Security review (red team pattern) ✅ Hackathon approach selection
❌ Simple implementation tasks ❌ Tasks with one obvious answer ❌ Sequential work with dependencies
Example Prompts
Architecture Debate
Question: "Should Nudge use Turso (SQLite) or Supabase (Postgres) for production?"
Agent 1: Argue for Turso — edge computing, simplicity, cost
Agent 2: Argue for Supabase — ecosystem, realtime, auth
Agent 3: Devil's advocate — what about a hybrid approach?
Trading Strategy
Question: "Is ETH undervalued at current levels given macro conditions?"
Agent 1: Bull case — on-chain metrics, upcoming catalysts
Agent 2: Bear case — macro headwinds, technical levels
Agent 3: Neutral — range-bound thesis with key levels to watch
Debug Investigation
Question: "App crashes on iOS 17 but not 18. What's the root cause?"
Agent 1: Investigate API deprecation changes
Agent 2: Investigate SwiftUI rendering pipeline differences
Agent 3: Investigate memory management changes
Integration with Swarm
The debate pattern works across the swarm:
- Sprint can debate hackathon approaches
- Quant can run bull/bear/neutral analysis
- Architect can evaluate design patterns
- Any agent can spawn a debate when facing a non-obvious decision
Future: Native Agent Teams
When OpenClaw supports Claude Code's agent teams natively:
- Agents will message each other directly (no file coordination)
- Shared task list replaces file-based progress tracking
- Lead can delegate without implementing
- This skill becomes a lightweight wrapper around native teams
