Modern portfolio theory optimization including Markowitz mean-variance, Black-Litterman, risk parity, and efficient frontier construction with constraints.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Portfolio Optimizer

## Purpose

Modern portfolio theory optimization including Markowitz mean-variance, Black-Litterman, risk parity, and efficient frontier construction with constraints.

## Routing

- Use when: Use when the user asks about portfolio optimization, asset allocation, efficient frontier, Markowitz optimization, Black-Litterman, risk parity, diversification, rebalancing, or optimal portfolio construction.
- Do not use when: Do not use when the request is about individual stock analysis, financial modeling, risk metrics only (use Risk Analyzer), or tax planning.
- Outputs: Outcome from Portfolio Optimizer: optimized asset allocation with weights, expected return, risk metrics, efficient frontier positioning, and rebalancing recommendations.
- Success criteria: Returns specific allocation weights, portfolio expected return and risk, Sharpe ratio, comparison to current allocation, and actionable rebalancing steps.

## Trigger Examples

### Positive

- Use the portfolio-optimizer skill for this request.
- Help me with portfolio optimizer.

How to install

The exact contents, by fingerprint
mdr add cowork-os/cowork-os/portfolio-optimizer@sha256:4a8a1372718949ef

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
