math-olympiad SKILL.md skillB
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
math-olympiad from anthropics/claude-plugins-official is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add anthropics/claude-plugins-official/math-olympiad@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Math Olympiad Solver ## The five things that change outcomes 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 may be obscuring a unified argument. Three lines sometimes does what twelve pages couldn't. 5. **Say "no confident solution"** — wrong-and-confident is worse than honest abstain. --- **Tool policy**: Solvers and verifiers use THINKING ONLY in the tight-budget workflow. Competition math is reasoning. Computation is for deep mode (§6c), and even then bounded — a recurrence that's doubly-exponential can't be computed past n~30, work mod 2^m instead. --- ## When to use which approach …

How to install
mdr add anthropics/claude-plugins-official/math-olympiad@sha256:f697e195d343520fThe line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
