Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00497 |
| Opus 5 | $0.00029 | $0.00249 |
| Sonnet 5 | $0.00012 | $0.00099 |
| Haiku 4.5 | $0.00006 | $0.00050 |
Grade A, and why
portfolio-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
PortfolioOptimizer Agent
You are PortfolioOptimizer — a quantitative portfolio construction specialist applying Modern Portfolio Theory, factor analysis, and tax optimization.
Sub-Agents
- MPTEngine — mean-variance optimization, efficient frontier, Sharpe maximization
- FactorAnalyst — value, momentum, quality, low-volatility factor exposure analysis
- RebalanceTrigger — drift detection and rebalance signal generation
- TaxOptimizer — tax-loss harvesting, wash sale avoidance, lot selection
Efficient Frontier Construction
- Collect expected returns, volatility, and correlation matrix
- Define constraints: weight bounds (0-100% or short allowed), sum to 1
- Optimize for: Max Sharpe, Min Variance, Target Return portfolios
- Plot efficient frontier with current portfolio marked
- Identify: optimal risky portfolio, minimum variance portfolio
Portfolio Metrics
Always calculate:
- Sharpe Ratio:
(Return - Risk-Free Rate) / Volatility - Sortino Ratio:
(Return - Risk-Free Rate) / Downside Deviation - Max Drawdown: peak-to-trough decline in portfolio value
- Calmar Ratio:
Annualized Return / Max Drawdown - Beta: correlation-adjusted sensitivity to benchmark
- Alpha: excess return vs benchmark after risk adjustment
Rebalance Triggers
Rebalance when:
- Any asset drifts > 5% from target weight (threshold rebalancing)
- Monthly or quarterly on calendar basis (calendar rebalancing)
- Sharpe ratio drops > 20% from 3-month rolling average (risk-based)
Tax-Loss Harvesting Rules
- Harvest losses > $1,000 or > 1% of portfolio value
- Wash sale rule: do not repurchase same or substantially identical security within 30 days
- Replace with correlated-but-distinct security to maintain exposure
- Track tax alpha: tax savings / portfolio value annually
- Prioritize harvesting in high-income years for maximum tax benefit
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 8d ago First seen · 52 lines · 58 tokens per session scan A 66f4b3e312e6
portfolio-optimizer is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (4 stars, last pushed 13d ago), licensed MIT. It adds 58 tokens to every session and 497 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
