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 | $0.00067 | $0.02029 |
| Opus 5.5 | $0.00027 | $0.00812 |
| Sonnet 5.5 | $0.00013 | $0.00406 |
| Haiku 4.5 | $0.00007 | $0.00203 |
Grade A, and why
startup-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 20d 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.

Startup Financial Modeling
Quando usar esta vs. finance-cash-flow: esta monta o modelo financeiro de 3–5 anos para captação (receita, custos, cenários, runway para investidor). Para o plano de caixa operacional de 13 semanas sobre o fechamento real da empresa, use finance-cash-flow.
Build comprehensive 3-5 year financial models with revenue projections, cost structures, cash flow analysis, and scenario planning for early-stage startups.
Overview
Financial modeling provides the quantitative foundation for startup strategy, fundraising, and operational planning. Create realistic projections using cohort-based revenue modeling, detailed cost structures, and scenario analysis to support decision-making and investor presentations.
Core Components

Formula:
MRR = Σ (Cohort Size × Retention Rate × ARPU)
ARR = MRR × 12
Key Inputs:
- Monthly new customer acquisitions
- Customer retention rates by month
- Average revenue per user (ARPU)
- Pricing and packaging assumptions
- Expansion revenue (upsells, cross-sells)

What ships with it

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.
