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

financial-modeling 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/saas-metrics.py, scripts/test_saas_metrics.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Financial Modeling

Use transparent assumptions, clearly labeled periods and units, and base/upside/downside scenarios. A model is a tool for exploring the implications of assumptions, not a prediction.

Analytical-aid boundary: This skill provides analytical frameworks, not financial, investment, tax, accounting, or legal advice. Verify inputs and calculations, and consult qualified professionals for decisions that require them.

When to Use

Load this skill when the task involves:

  • Building or reviewing a P&L, balance sheet, cash-flow, revenue, cost, or runway model
  • Calculating CAC, LTV, contribution margin, CAC payback, or segment-level unit economics
  • Evaluating pricing, packaging, price changes, or monetization
  • Preparing fundraising scenarios, a cap table, valuation analysis, or term-sheet questions
  • Analyzing SaaS ARR/MRR, churn, retention, NDR, Rule of 40, Magic Number, or burn multiple
  • Running sensitivity analysis or comparing base, upside, and downside cases

When Not to Use

  • For statistical inference, experiment design, causal analysis, or general model selection, use data-scientist.
  • For insurance, actuarial, claims, reserving, solvency, credibility, tail-risk, or financial-risk statistical models, use actuarial-risk-modeling.
  • For the narrow question of whether a startup reaches profitability before cash runs out, use yc-default-alive-calculator.
  • Do not use this skill as a substitute for licensed financial, investment, tax, accounting, or legal advice.
  • Enterprise pricing negotiations, jurisdiction-specific securities rules, and tax/accounting treatment need specialist review beyond this skill.

Reference Guide

Load only the reference relevant to the task:

Reference Load when
Unit economics Calculating CAC, LTV, payback, gross margin, or contribution margin
Financial modeling Building linked statements, revenue and cost models, scenarios, or runway
Pricing strategy Evaluating value, packaging, tiers, price changes, or elasticity
Fundraising Reviewing valuation methods, cap tables, term sheets, or fundraising process
SaaS metrics Defining and interpreting ARR, churn, NDR, Rule of 40, Magic Number, or burn multiple
Source index Reviewing provenance, porting scope, source URLs, and currency boundaries

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.
