## What it does

The skill serves as a navigation map for mathematical computations and theorem checks. It categorizes tasks across distinct layers, from symbolic algebra in SymPy and constraint verification in Z3 to tutoring hints and formal proofs in Lean 4.

Inside, the guide documents CLI syntax with `uv run python` for repository scripts like `sympy_compute.py`, `z3_solve.py`, and `math_scratchpad.py`. For numerical workloads, it lists NumPy with 160 functions, SciPy with 289 functions, and mpmath with 153 arbitrary-precision functions. Plotting is handled through `math_plot.py` with 2D, 3D, and LaTeX rendering support.

The frontmatter sets `user-invocable: false`. You do not call it directly as a command. The assistant retrieves this guide automatically whenever triggered by phrases like "math help" or questions about which tool to pick.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill math-help -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/math-help/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/math-help/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill math-help -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/math-help/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill math-help -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/math-help/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 math-help
```

2. **Manually: put the files in place**
- File: `.github/skills/math-help/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill math-help -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/math-help
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/math-help/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill math-help -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/math-help/SKILL.md

## When to use it
- choose the right math tool for symbolic, numerical, or formal tasks
- find ready CLI commands for limits, differentiation, and integrals in SymPy
- verify satisfiability and solve constraint proofs with Z3
- validate step-by-step mathematical reasoning via `math_scratchpad.py`

## Example prompts
- math help: how do I solve an equation with sympy_compute.py?
- which tool should I use to check a chain of reasoning steps?
- how do I run numerical minimization with scipy_compute.py?

# Math Cognitive Stack Guide

Cognitive prosthetics for exact mathematical computation. This guide helps you choose the right tool for your math task.

## Quick Reference

| I want to... | Use this | Example |
|--------------|----------|---------|
| Solve equations | sympy_compute.py solve | `solve "x**2 - 4 = 0" --var x` |
| Integrate/differentiate | sympy_compute.py | `integrate "sin(x)" --var x` |
| Compute limits | sympy_compute.py limit | `limit "sin(x)/x" --var x --to 0` |
| Matrix operations | sympy_compute.py / numpy_compute.py | `det "[[1,2],[3,4]]"` |
| Verify a reasoning step | math_scratchpad.py verify | `verify "x = 2 implies x^2 = 4"` |
| Check a proof chain | math_scratchpad.py chain | `chain --steps '[...]'` |
| Get progressive hints | math_tutor.py hint | `hint "Solve x^2 - 4 = 0" --level 2` |
| Generate practice problems | math_tutor.py generate | `generate --topic algebra --difficulty 2` |
| Prove a theorem (constraints) | z3_solve.py prove | `prove "x + y == y + x" --vars x y` |
| Check satisfiability | z3_solve.py sat | `sat "x > 0, x < 10, x*x == 49"` |
| Optimize with constraints | z3_solve.py optimize | `optimize "x + y" --constraints "..."` |
| Plot 2D/3D functions | math_plot.py | `plot2d "sin(x)" --range -10 10` |
| Arbitrary precision | mpmath_compute.py | `pi --dps 100` |

## The Five Layers

### Layer 1: SymPy (Symbolic Algebra)

**When:** Exact algebraic computation - solving, calculus, simplification, matrix algebra.

**Key Commands:**
```bash
# Solve equation
uv run python -m runtime.harness scripts/sympy_compute.py \
    solve "x**2 - 5*x + 6 = 0" --var x --domain real

# Integrate
uv run python -m runtime.harness scripts/sympy_compute.py \
    integrate "sin(x)" --var x

# Definite integral
uv run python -m runtime.harness scripts/sympy_compute.py \
    integrate "x**2" --var x --bounds 0 1

# Differentiate (2nd order)
uv run python -m runtime.harness scripts/sympy_compute.py \
    diff "x**3" --var x --order 2

# Simplify (trig strategy)
uv run python -m runtime.harness scripts/sympy_compute.py \
    simplify "sin(x)**2 + cos(x)**2" --strategy trig

# Limit
uv run python -m runtime.harness scripts/sympy_compute.py \
    limit "sin(x)/x" --var x --to 0

# Matrix eigenvalues
uv run python -m runtime.harness scripts/sympy_compute.py \
    eigenvalues "[[1,2],[3,4]]"
```

**Best For:** Closed-form solutions, calculus, exact algebra.

### Layer 2: Z3 (Constraint Solving & Theorem Proving)

**When:** Proving theorems, checking satisfiability, constraint optimization.
