math-olympiad

anthropics/claude-plugins-official/plugins/math-olympiad/skills/math-olympiad/SKILL.md

1. Strip thinking before verifying — a verifier that sees the reasoning is biased toward agreement. Fresh context, cleaned proof only. 2. "Does this prove RH?" — if your theorem's specialization to ζ is a famous open problem, you have a gap. Most reliable red flag. 3. Short proof → extract the general lemma — try 2×2 counterexamples. If general form is false, find what's special about THIS instance. 4. Same gap twice → step back — the case split…

siege

anthropics/claude-plugins-official/plugins/math-proof/skills/siege/SKILL.md

Work on one hard mathematics problem in rounds: each round a judge writes a few self-contained questions, independent workers answer them, and the judge keeps a ledger of what is proved, refuted and open, until the judge concludes or the rounds run out, and then a proof.md says plainly what is and is not proved. A run takes hours and dozens of worker runs. Usage: /math-proof:siege [NAME=value settings] <the problem, stated in full, or the path of a file holding it>.
