Run Monte Carlo simulations for Finance Guru portfolio strategy.

  • User mentions monte carlo OR run simulation OR stress test portfolio OR probability analysis OR income projections OR margin safety analysis
  • SKILL.md covers Workflow Routing, Examples, Key Metrics Produced and Output Files, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Load testing

What it does

Monte Carlo is an agent skill from AojdevStudio/Finance-Guru. Run Monte Carlo simulations for Finance Guru portfolio strategy. USE WHEN user mentions monte carlo OR run simulation OR stress test portfolio OR probability analysis OR income projections OR margin safety analysis. Supports a 4-layer portfolio (Growth, Income, Hedge, GOOGL) with operator-supplied starting values.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `PortfolioParser.md`, `workflows/IncorporateBuyTicket.md` and `workflows/RunSimulation.md`).

It sits in Testing & QA, covering Load testing. The repository describes itself as: Self-hosted family office engine: typed Python calculators, a private SQLite ledger, and specialist agents for Claude Code and Codex. Agents propose. Typed code computes.

When your agent uses it

  • User mentions monte carlo OR run simulation OR stress test portfolio OR probability analysis OR income projections OR margin safety analysis
  • Tasks that involve Load testing

Example prompts

  • “/monte-carlo”

What it can do on your machine

Read from SKILL.md and the folder at commit a81bcd7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Monte Carlo loads about 1k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 336 words (~1,036 tokens).

“Monte Carlo simulation engine for Finance Guru's 4-layer dividend income + margin living strategy. Runs 10,000 market scenarios to project income probabilities, margin safety, and portfolio outcomes over 28 months.”
