# lbo-model

Fills in an LBO model template in Excel with live formulas, checks the math and keeps formatting consistent. Handy when deal materials are due.

## What it does

The skill starts from a template rather than a blank workbook. Attach one and it copies that structure, then populates it with your assumptions. Attach nothing and it asks whether you have your own, offering a standard layout with sources and uses, an operating model, a debt schedule and a returns analysis. That default lives at `examples/LBO_Model.xlsx`.

Two environments are supported. Inside a live Excel session the skill writes formulas through Office JS, so the workbook recalculates on its own. For a standalone `.xlsx` it uses Python and openpyxl, writing formula strings and running `recalc.py` before delivery. Calculations stay as formulas either way, which means the model moves when your inputs move.

Formatting follows a fixed scheme: blue font for typed inputs, black for formulas, purple for same-sheet links, green for cross-sheet ones, with fills limited to blues and greys. The skill builds one section at a time and checks with you before moving on, since a wrong number in sources and uses only surfaces once returns are already built. In Office JS, write the value to the top-left cell before merging a range — merging first throws `InvalidArgument`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/financial-services --skill lbo-model -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/financial-services --skill lbo-model -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add anthropics/financial-services --skill lbo-model -a cursor
```

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

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/anthropics/financial-services --path plugins/agent-plugins/model-builder/skills/lbo-model
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add anthropics/financial-services --skill lbo-model -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/anthropics/financial-services/tree/HEAD/plugins/agent-plugins/model-builder/skills/lbo-model/SKILL.md

## When to use it
- fill an LBO template with formulas instead of typing numbers
- lay out sources and uses in one place
- build a debt schedule across periods
- work out IRR, MOIC and exit returns
- standardise formatting before the model goes to review

## Example prompts
- Fill the attached LBO template using my assumptions on the Assumptions tab
- Build the standard buyout model: sources and uses, operating model, debt schedule, returns analysis
- Check the formulas in Returns Analysis and flag anything that doesn't tie

## TEMPLATE REQUIREMENT

**This skill uses templates for LBO models. Always check for an attached template file first.**

Before starting any LBO model:
1. **If a template file is attached/provided**: Use that template's structure exactly - copy it and populate with the user's data
2. **If no template is attached**: Ask the user: *"Do you have a specific LBO template you'd like me to use? If not, I can use the standard template which includes Sources & Uses, Operating Model, Debt Schedule, and Returns Analysis."*
3. **If using the standard template**: Copy `examples/LBO_Model.xlsx` as your starting point and populate it with the user's assumptions

**IMPORTANT**: When a file like `LBO_Model.xlsx` is attached, you MUST use it as your template - do not build from scratch. Even if the template seems complex or has more features than needed, copy it and adapt it to the user's requirements. Never decide to "build from scratch" when a template is provided.

## CRITICAL INSTRUCTIONS FOR CLAUDE - READ FIRST

### Environment: Office JS vs Python

**If running inside Excel (Office Add-in / Office JS environment):**
- Use Office JS (`Excel.run(async (context) => {...})`) directly — do NOT use Python/openpyxl
- Write formulas via `range.formulas = [["=B5*B6"]]` — Office JS formulas recalculate natively in the live workbook
- The same formulas-over-hardcodes rule applies: set `range.formulas`, never `range.values` for anything that should be a calculation
- Use `range.format.font.color` / `range.format.fill.color` for the blue/black/purple/green convention
- No separate recalc step needed — Excel handles calculation natively
- **Merged cell pitfall:** Do NOT call `.merge()` then set `.values` on the merged range (throws `InvalidArgument` — range still reports original dimensions). Instead: write value to top-left cell alone (`ws.getRange("A7").values = [["SOURCES & USES"]]`), then merge + format the full range (`ws.getRange("A7:F7").merge(); ws.getRange("A7:F7").format.fill.color = "#1F4E79";`)
```
