Use when spawning subagents for complex research, code review, architecture decisions, or risk assessment. Triggers on: 'adversarial team', 'devil's advocate analysis', 'multi-perspective review', 'challenge this decision', 'stress test this plan', 'red team this'." source: ai-berkshire/xbtlin (MIT) — pattern adapted from investment-team.md four-master debate model tier: TIER 2 — CORRECTNESS
Adversarial Team Pattern
Multi-agent analysis using opposing mandates — not consensus. Agents challenge each other rather than reinforce each other.
Core principle: consensus from multiple agents = one agent with extra compute. Value comes from productive disagreement.
When to use
- High-stakes decisions (architecture, security, major refactor)
- Analysis where confirmation bias is a real risk
- Any time you'd normally just "get a second opinion" (make it an adversarial second opinion)
- Code review of critical paths
- Research where you want to surface what could go wrong, not just what looks right
Do NOT use for: simple lookups, single-file changes, mechanical tasks with a clear right answer.
Team structure
Spawn these roles in a single message (parallel, run_in_background: true):
ROLE A — AdvocateMandate: Build the strongest case FOR the proposal.Find evidence that supports it. Assume it will work.Deliver: 3–5 concrete supporting arguments with evidence.ROLE B — ChallengerMandate: Find everything wrong with the proposal.Assume it will fail. Find the weakest points.Deliver: 3–5 specific failure modes or risks with evidence.ROLE C — Constraint FinderMandate: Find what's missing, what's not accounted for,what the other two missed. Be the skeptic of both sides.Deliver: unknowns, edge cases, unstated assumptions.ROLE D — Synthesizer (run AFTER A, B, C complete)Mandate: Read all three reports. Produce a forced conclusion.Cannot say "it depends". Must pick a side or a modified path.Deliver: verdict + confidence % + 1 concrete next action.
Execution template
Analyze [TOPIC] using adversarial team pattern.Agent A (Advocate): Make the strongest case FOR [TOPIC].Find 3–5 concrete supporting arguments with evidence.Do not hedge. Assume success.Agent B (Challenger): Find everything wrong with [TOPIC].Find 3–5 specific failure modes or risks.Assume failure. Do not soften findings.Agent C (Constraint Finder): Find what A and B both missed.Surface unknowns, unstated assumptions, edge cases.Be skeptical of both the advocate and challenger.After all three complete, Agent D (Synthesizer) reads all reportsand produces a forced conclusion: verdict + confidence % + next action.No "it depends" in the conclusion.
Output Contract
Advocate findings: [3–5 supporting arguments]Challenger findings: [3–5 failure modes]Missing/unknowns: [what neither side saw]VERDICT: [clear position — not neutral]CONFIDENCE: [0–100%]REASONING: [which argument won and why]NEXT ACTION: [one concrete step]
In-Skill Verification
Before Synthesizer produces verdict:
- Check: did Advocate cite at least 1 concrete piece of evidence (not just assertion)?
- Check: did Challenger identify at least 1 specific failure mode (not generic risk)?
- If either check fails → Synthesizer notes "incomplete input" in output with confidence ≤ 50%
Anti-patterns
❌ All agents instructed to "analyze objectively" — that's consensus, not adversarial❌ Synthesizer allowed to conclude "both sides have merit, consider your context"❌ Challenger role that softens findings ("on the other hand, it could work if...")❌ Running agents sequentially where later agents read earlier agents' output (anchoring bias)❌ Skipping Synthesizer — raw debate without forced conclusion wastes the pattern
Confidence calibration
| Situation | Max confidence | |
|---|---|---|
| All 3 roles agree | 90% | |
| Advocate + Synthesizer agree, Challenger has weak evidence | 75% | |
| Split between roles, Synthesizer forced to pick | 60% | |
| Missing data flagged by Constraint Finder | 50% | |
| Insufficient evidence from any role | 35% |
