## What it does

This skill formalizes operational workflows for portfolio management systems, such as Orion, Black Diamond, Tamarac, and Addepar. It treats the PMS as the firm's Investment Book of Record (IBOR). Reconciliations run daily against custodian records across cash, transactions, and positions.

The skill defines structure for Unified Managed Accounts (UMA) divided into virtual sleeves. It outlines cash waterfall priorities and drift monitoring thresholds from conservative (3%/15%) to wide (7%/30%). Rebalancing logic addresses tax-loss harvesting alongside wash sale constraints. Held-away assets integrate through Plaid or Yodlee.

The guide centers on portfolio modeling and data integrity. For in-depth trade execution and billing formulas, the reference explicitly directs users to `order-management-advisor` and `fee-billing`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill portfolio-management-systems -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill portfolio-management-systems -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill portfolio-management-systems -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install JoelLewis/finance_skills portfolio-management-systems
```

2. **Manually: put the files in place**
- File: `.github/skills/portfolio-management-systems/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill portfolio-management-systems -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/JoelLewis/finance_skills --path plugins/advisory-practice/skills/portfolio-management-systems
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill portfolio-management-systems -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/JoelLewis/finance_skills/tree/HEAD/plugins/advisory-practice/skills/portfolio-management-systems/SKILL.md

## When to use it
- establish cash waterfall allocation rules for UMA accounts
- set absolute and relative drift monitoring thresholds
- run daily IBOR reconciliations against custodian records
- choose return calculation models between TWR and MWR

## Example prompts
- Configure conservative drift thresholds for our model portfolios in Black Diamond.
- How should we distribute cash deposits across UMA sleeves using a waterfall?
- Outline a daily reconciliation process between our PMS and custodian records.

> UMA/SMA/wrap comparison table; §4 drift measurement formulas, threshold configurations, or
> tax-aware rebalancing logic; §5 aggregation data sources and data-quality failure modes;
> §6 break-resolution workflow, corporate-action types, or cost basis methods; §8 daily vs.

> integration methods, and feed timing. (Reference §7 trading and §9 billing are pointers to

### 1. Portfolio Management System Architecture

The PMS is the operational nerve center of an advisory practice, orchestrating data flow between custodians, trading platforms, reporting engines, CRM, and planning tools. Core functions include portfolio construction, model management, rebalancing, trading, performance reporting, and billing. Major platforms: Orion, Black Diamond, Tamarac, Addepar, Morningstar Direct, Advent/APX. The PMS serves as the firm's Investment Book of Record (IBOR), which must be reconciled daily against the custodian's Official Book of Record (OBOR).

### 2. Model Portfolio Management
