## Description

Work on one hard mathematics problem in this session yourself, with no sub-agents: reason in stages, record each settled step in a notes file so that nothing written is lost if a response is cut off, and end with a self-contained proof.md. Usage: /math-proof:solo <the problem, stated in full, or the path of a file holding it>.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# math-proof: solo

You solve the problem yourself, in this session. There are no sub-agents and no rounds: just you, a notes
file and, at the end, proof.md.
