math-olympiad

Competition math solver with adversarial verification.

The problem

Self-verification gets fooled. A verifier that sees the reasoning is biased toward agreement. arXiv:2503.21934 ("Proof or Bluff") showed 85.7% self-verified IMO success drops to <5% under human grading.

The approach

• Context-isolated verification: verifier sees only the clean proof, never the reasoning trace
• Pattern-armed adversarial checks: not "is this correct?" but "does this accidentally prove RH?" / "extract the general lemma, find a 2×2 counterexample"
• Calibrated abstention: says "no confident solution" rather than bluff
• Presentation pass: produces clean LaTeX/PDF after verification passes

Validation

17/18 IMO+Putnam 2025 problems solved, 0 false positives, 2 novel proofs found. See the skill's eval data in the anthropic monorepo.
