Math Skill — Development skill for Claude Code

math-skill

A Claude skill for solving math problems rigorously — from quick calculations to full proofs.

What it does

This skill makes Claude a careful, solver-first math assistant. Instead of jumping straight to an answer, it maps the problem, selects the right method, works through each step explicitly, and verifies the result before presenting it. The goal is answers you can actually trust.

It works with typed problems and with photos — snap a handwritten problem, a whiteboard, or a textbook page and Claude will transcribe it carefully before solving.

Solving modes

Mode	What you get
solver (default)	Full problem map, method choice, step-by-step derivation, independent verification
photo-solver	Transcribe from image first, then solve and verify
fast-answer	Concise output, but mapping and verification still happen internally
worked-solution	Full derivation with the key insight made explicit
proof	Exploration separated from the final clean argument
exam	Minimal exposition, essential steps only, answer easy to grade
tutor	Reveals the next move rather than the full solution at once

Educational modes (`lesson`, `worksheet`, `diagnostic`, `review`, `primary-school`) are also available when you want teaching materials rather than a solution.

What kinds of problems it handles

• Equations and systems (linear, polynomial, transcendental)
• Inequalities and optimization
• Proofs and number theory
• Counting, combinatorics, and probability
• Sequences, recurrences, and series
• Calculus — limits, derivatives, integrals
• Geometry and trigonometry
• Word problems and modeling
• Reading math from photos, screenshots, PDFs, and handwritten notes

Verification tools

The skill ships with Python helpers that Claude uses to double-check its own work:

• math_verify.py — checks expression equivalence, derivatives, integrals, equation solutions, limits, and counterexample
