## What it does

This skill handles retirement math and tax location strategies. The logic relies on academic research. It uses Modern Portfolio Theory and dynamic withdrawal frameworks like Guyton-Klinger. The assistant models sequence of returns risk and estimates safe withdrawal rates based on the CAPE ratio.

Computations rely on Bash commands and search via WebFetch. Running Monte Carlo simulations requires external packages. You need to install `numpy`, `scipy`, and `pandas` via pip. Core formulas are kept in markdown files under `references/`.

It will not pick individual stocks. The skill does not replace a CPA or a licensed fiduciary advisor. It cannot prepare tax filings and guarantees no investment returns.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add curiositech/some_claude_skills --skill personal-finance-coach -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add curiositech/some_claude_skills --skill personal-finance-coach -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add curiositech/some_claude_skills --skill personal-finance-coach -a cursor
```

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

### GitHub Copilot

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/curiositech/some_claude_skills --path .claude/skills/personal-finance-coach
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add curiositech/some_claude_skills --skill personal-finance-coach -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/curiositech/some_claude_skills/tree/HEAD/.claude/skills/personal-finance-coach/SKILL.md

## When to use it
- calculate safe withdrawal rates based on the CAPE ratio
- model a Roth conversion ladder for early retirement
- allocate assets between taxable and tax-advantaged accounts
- evaluate retirement plans against sequence of returns risk

## Example prompts
- Calculate my Coast FIRE target based on annual expenses
- Show me an asset location plan across taxable and tax-deferred accounts
- Estimate my safe withdrawal rate using the current CAPE ratio
