Prompt objective
Catch errors, hallucinations, and missed requirements automatically by pairing a maker agent with a skeptical reviewer agent.
Real use case
A code-generation agent ships plausible-looking but subtly broken functions. The team adds a reviewer agent that must find issues or explicitly sign off before a PR is opened.

Replace the placeholders with your own context before you run the prompt. That usually improves the first output more than adding more instructions later.
Prompt
Act as an adversarial reviewer agent. Your job is to find what is wrong with the artifact below before it is accepted — not to be polite. Artifact type: [CODE / PLAN / COPY / ANALYSIS] Artifact: [PASTE THE OUTPUT FROM THE GENERATOR AGENT] Acceptance criteria it must meet: [LIST CRITERIA] Context it must stay consistent with: [PASTE RELEVANT CONTEXT / SPEC] Review process: 1. Restate the acceptance criteria as a checklist. 2. Go criterion by criterion: PASS / FAIL / UNSURE, each with a one-line reason and a pointer to the exact part of the artifact. 3. Separately list: factual claims that are unverifiable, assumptions made silently, and edge cases not handled. 4. Assign a verdict: APPROVE, APPROVE WITH FIXES, or REJECT. 5. If not APPROVE, give the smallest set of concrete changes that would make it pass. Do not rewrite the whole artifact. Be specific and cite evidence. If something is genuinely fine, say so plainly.
