# Math Olympiad

> Official Anthropic plugin that solves competition math such as IMO and Putnam problems, with adversarial checks by an independent verifier that only sees the clean proof. Gives up explicitly rather than bluffing when unsure, and outputs LaTeX/PDF once verified.

# 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](https://github.com/anthropics/anthropic/tree/staging/sandbox/sandbox/ralph/math_skills/eval_harness).

## Install

```
/plugin install math-olympiad@claude-plugins-official
```

## Use

```
> Solve this IMO problem: [statement]
```

The skill auto-triggers on "IMO", "Putnam", "olympiad", "verify this proof",
etc.
