## What it does

The skill reads your ETF request and picks the matching workflow. Right now the index holds one route, `workflows/etf-overlap-report.md`, which covers holdings comparison, overlap, concentration and exposure breakdowns.

It starts by pinning down the tickers, the comparison universe, the as-of date and the output you want. Then it opens only that workflow and the local resources it needs. Holdings, fund metadata, prices and coverage notices come from LLMQuant Data: issuer, category, expense ratio, market price, NAV, weighted holdings with sectors and countries, plus price and fund-flow history.

When coverage for a ticker is unsupported, the skill names the ticker and the identifiers it needs instead of guessing. No LLMQuant Data or compatible data MCP? You supply issuer holdings files or tables. Approximating holdings from memory is off the table. Every report carries `as_of_date`, source, stale flags and missing fields, so check the date before you act on the weights.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-etfs -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-etfs -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-etfs -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install LLMQuant/skills llmquant-etfs
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-etfs -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/LLMQuant/skills --path skills/llmquant-etfs
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add LLMQuant/skills --skill llmquant-etfs -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/LLMQuant/skills/tree/HEAD/skills/llmquant-etfs/SKILL.md

## When to use it
- compare holdings across two ETFs and surface overlap
- measure top-name concentration in a fund
- break an ETF down by sector and country exposure
- pull an issuer and category snapshot for a ticker
- track fund-flow and price history

## Example prompts
- compare SPY and IVV holdings, show overlap and concentration
- break QQQ down by sector as of quarter end
- give me an issuer and expense ratio snapshot for VTI

# LLMQuant ETFs

This category routes ETF analysis tasks to holdings and exposure workflows.

## Routing Rules

1. Identify the ETF tickers, comparison universe, as-of date, and required output.
2. Select the closest workflow below.
3. Open only the selected workflow and required local resources.
4. Use LLMQuant Data for holdings, fund metadata, prices, and coverage notices.
5. Report holdings `as_of_date`, source, stale flags, unsupported tickers, and missing fields.

## Workflow Index

| User intent | Workflow |
|---|---|
| Compare ETF holdings, overlap, concentration, and exposure. | [`workflows/etf-overlap-report.md`](workflows/etf-overlap-report.md) |

## LLMQuant Data Contract

Prefer LLMQuant Data when available. The workflows may need these data capabilities:
- Look up ETF identity, issuer, category, expense ratio, market price, NAV, and coverage status.
- Retrieve ETF holdings with weights, identifiers, sectors, countries, source, and holdings as-of date.
- Compare ETF holdings overlap, top-name concentration, and exposure breakdowns.
- Retrieve price history, fund-flow history, and sector exposure history when available.

Fallback:
- If holdings coverage is unsupported, report the unsupported ticker and the ETF identifiers needed.
- If LLMQuant Data or a compatible data MCP is unavailable, ask the user for issuer holdings files or holdings tables.
- Do not approximate holdings from memory.
