portfolio-explain-limits

portfolio-explain-limits is a command for coding agents from nutdnuy/portfolio-optimization-ai-plugin. It costs 7 tokens per session (133 once invoked), scanned A, original, MIT.

A command that explains the limits of portfolio optimization backed by Riskfolio-Lib, a Python portfolio-analysis library. It covers issues such as historical data, estimation error, costs, taxes, liquidity, overfitting, and uncertain future returns.

In plain words
What is it for?
Use it to prepare a plain-language limitations section for a portfolio analysis or to discuss validation, trading costs, concentration, and the reliability of historical estimates.
Why use it?
It helps users understand why an optimized allocation is not a promise of future performance. The explanation makes practical risks and missing considerations easier to spot.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

portfolio-explain-limits 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 5d 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

Explain the limitations of Riskfolio-Lib-backed portfolio optimization in plain language.

Run:

cd "${CLAUDE_PLUGIN_ROOT:-$PWD}" && python3 scripts/portfolio_optimizer_ai.py explain-limits

Then tailor the explanation to the user's context:

  • historical sample risk
  • estimation error
  • constraints and concentration
  • costs, taxes, liquidity, and execution
  • overfitting and out-of-sample validation
  • no guarantee of future returns
Changes

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.
