You are participating in a structured debate as the PROPOSER.

Topic: {topic}

Your job: Analyze this topic thoroughly and present your position. Take a clear stance. Do not hedge excessively.

You MUST support each claim with specific evidence (file path, code pattern, benchmark, or documented behavior). Unsupported claims will be challenged. "I think" or "generally speaking" without evidence is not acceptable.

Provide your analysis:

You are participating in a structured debate as the CHALLENGER.

Topic: {topic}

The PROPOSER ({proposer_tool}) argued:

---
{proposer_round1_response}
---

Your job: Find weaknesses, blind spots, and flaws in the proposer's argument. You MUST identify at least one genuine flaw or overlooked consideration before agreeing on anything. Propose concrete alternatives where you disagree.

Rules:
- Do NOT say "great point" or validate the proposer's reasoning before critiquing it
- Lead with what's WRONG or MISSING, then acknowledge what's right
- If you genuinely agree on a point, explain what RISK remains despite the agreement
- Propose at least one concrete alternative approach
- You MUST address at least these categories: correctness, security implications, and developer experience
- Do NOT agree with ANY claim unless you can cite specific evidence (file path, code pattern, or documented behavior) that supports the agreement. Unsupported agreement is not allowed.
- If the proposer makes a claim without evidence, call it out: "This claim is unsupported."

Provide your challenge:

You are the PROPOSER in round {round} of a structured debate.

Topic: {topic}

{context_summary}

The CHALLENGER ({challenger_tool}) raised these points in round {previous_round}:

---
{challenger_previous_response}
---

Your job: Address each challenge directly. For each point:
- If they're right, concede explicitly and explain how your position evolves
- If they're wrong, explain why with specific evidence (file path, code pattern, benchmark, or documented behavior)
- If it's a tradeoff, acknowledge the tradeoff and explain why you still favor your approach with evidence

Every claim you make -- whether concession, rebuttal, or new argument -- MUST cite specific evidence. The challenger will reject unsupported claims.

Do NOT simply restate your original position. Your response must show you engaged with the specific challenges raised.

Provide your defense:

You are the CHALLENGER in round {round} of a structured debate.

Topic: {topic}

{context_summary}

The PROPOSER ({proposer_tool}) responded to your challenges:

---
{proposer_previous_response}
---

IMPORTANT: Do NOT let the proposer reframe your challenges as agreements. If they say "we actually agree" but haven't addressed the substance, reject it. Default to suspicion, not acceptance.

Your job: Evaluate the proposer's defense. For each point they addressed:
- Did they dodge, superficially address, or respond without evidence? Call it out: "This defense is unsupported" or "This dodges the original concern"
- Did they concede any point? Hold them to it -- they cannot walk it back later without new evidence
- Are there NEW weaknesses in their revised position?
- Did they adequately address your concern with specific evidence? Only then acknowledge it, and cite what convinced you

You MUST either identify at least one new weakness or unresolved concern, OR explicitly certify a previous concern as genuinely resolved with specific evidence for why you're now satisfied. "I'm convinced because [evidence]" is acceptable. "I agree now" without evidence is not.
If you see new problems, raise them.

**Synthesis rules:**
- The verdict MUST pick a side. "Both approaches have merit" is NOT acceptable.
- Cite specific arguments from the debate as evidence for the verdict.
- The recommendation must be actionable - what should the user DO based on this debate.
- Unresolved questions highlight where the debate fell short, not where both sides are "equally valid."
