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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00085 | $0.01933 |
| Opus 5 | $0.00043 | $0.00966 |
| Sonnet 5 | $0.00017 | $0.00387 |
| Haiku 4.5 | $0.00009 | $0.00193 |
Grade A, and why
biz-cac-ltv 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 10d 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.

CAC and LTV Analysis
Overview
CAC (Customer Acquisition Cost) and LTV (Customer Lifetime Value) are the two fundamental unit economics metrics. Together they answer: "Does each customer generate more revenue than it costs to acquire them?" The LTV:CAC ratio is the single most important indicator of marketing efficiency and business model viability.
When to Use
Trigger conditions:
- User evaluating marketing spend efficiency
- User asks "what's each customer worth?" or "are we spending too much on marketing?"
- User assessing business model viability or fundraising metrics
- User needs to allocate budget across acquisition channels
When NOT to use:
- For product pricing decisions → use Pricing Strategy
- For customer segmentation → use STP or RFM
- For comprehensive financial analysis → use financial ratios
Framework
IRON LAW: LTV:CAC > 3 for Healthy Business
LTV:CAC ratio must be at least 3:1 for sustainable businesses.
- < 1:1 = You're LOSING money on every customer
- 1-3:1 = Unsustainable unless you can reduce CAC or increase LTV
- 3-5:1 = Healthy
- > 5:1 = Potentially underinvesting in growth (leaving market share on the table)
This ratio applies to the BLENDED average. Individual channels can be
below 3:1 if the overall blend exceeds it.
IRON LAW: CAC Must Include ALL Acquisition Costs
CAC = Total marketing & sales spend / Number of new customers acquired
"Total spend" includes: ad spend, marketing team salaries, sales team
salaries, tools, content production, events — EVERYTHING spent to acquire
customers in that period. Excluding salaries or tools understates true CAC.
Step 1: Calculate CAC
Basic formula:
CAC = Total acquisition spend in period / New customers acquired in period
By channel:
CAC (Channel X) = Spend on Channel X / Customers from Channel X
Include in total acquisition spend:
- Advertising (digital + offline)
- Marketing team compensation
- Sales team compensation (for B2B)
- Marketing tools and software
- Content production costs
- Events and sponsorships
- Agency fees

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.
