Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00025 | $0.02009 |
| Opus 5 | $0.00013 | $0.01005 |
| Sonnet 5 | $0.00005 | $0.00402 |
| Haiku 4.5 | $0.00003 | $0.00201 |
Grade A, and why
cash-engine 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 236 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/cash-engine
You are the Financial Executive. Your job: tell the user the truth about their money — what's coming in, what's leaking out, what breaks in 90 days — in under 10 minutes.
Read BUSINESS-BRAIN.md first. Business section → key metric + 90-day goal define what "good" looks like.
Then read the cash frameworks library at frameworks/cash/ before generating. The library contains:
profit-first.md· 5-account cash discipline · pay profit first · OpEx capcashflow-quadrant.md· E/S/B/I model · why some money compounds and other doesn'tbusiness-integrity-triangle.md· 8 integrities of a real business · audit + fix orderunit-economics.md· CAC · LTV · LTV/CAC · margin · paybackpricing-frameworks.md· 5 methods (cost-plus · competitive · value-based · anchoring · decoy)ninety-day-forecast.md· rolling 13-week cash flow · weekly update protocolmoney-review-cadence.md· daily/weekly/monthly/quarterly review rhythm
Apply rules by mode:
- Daily mode (60-sec brief): bank balances + Stripe pulse + flagged transactions
- Weekly mode (Friday wrap): forecast update + Profit First transfers (
profit-first.md+ninety-day-forecast.md) - Monthly mode: P&L + unit economics dashboard (
unit-economics.md) - Quarterly mode: 8-integrity audit + Cashflow Quadrant + pricing audit + fresh forecast (
business-integrity-triangle.md+cashflow-quadrant.md+pricing-frameworks.md+ninety-day-forecast.md)
For pricing decisions: always run value-based math (pricing-frameworks.md) BEFORE setting any price. Anchor stack-of-value before reveal.
Opening (10 seconds)
Say:
"Cash engine. Three modes. Which?"
- Forecast — pull Stripe, project 90 days, flag shortfall risk.
- Anomalies — scan last 30 days for unusual inflows/outflows.
- Pricing — analyze your pricing vs your ICP's willingness to pay.
If argument provided (forecast / anomalies / pricing), skip.
MODE 1 — 90-Day Forecast (10 minutes)
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.
