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 | $0.00055 | $0.00870 |
| Opus 5.5 | $0.00022 | $0.00348 |
| Sonnet 5.5 | $0.00011 | $0.00174 |
| Haiku 4.5 | $0.00006 | $0.00087 |
Grade A, and why
unit-economics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unit Economics
Analyze unit economics for "$ARGUMENTS". Calculate the fundamental economics of acquiring and serving a customer to determine whether the business model is sustainable and scalable.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/finance/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Compute with code. Perform every calculation (totals, balances, ratios, variances, projections) with a script — Bash, Python or a spreadsheet formula written to a file — and include the computation alongside the result. Never do arithmetic mentally.
Prerequisites
None — utility skill, run anytime. Works best when financial data exists in .metapowers/finance/<project>/.
Process
-
Gather context:
- If prior phase artifacts exist, read them for revenue and cost data
- Ask for customer count, revenue, and cost data
- Determine the business model (subscription, transactional, marketplace, etc.)
-
Calculate acquisition economics:
- Customer Acquisition Cost (CAC): total sales + marketing spend / new customers
- Break down CAC by channel (organic, paid, referral, outbound)
- Track CAC trend over time (improving or worsening)
- Calculate blended and fully-loaded CAC
-
Calculate lifetime value:
- Average Revenue Per User (ARPU): monthly and annual
- Gross margin per customer: ARPU - direct costs per customer
- Customer lifetime: 1 / monthly churn rate
- Lifetime Value (LTV): gross margin per customer x customer lifetime
- Segment LTV by customer cohort, plan, or channel if data available
-
Calculate efficiency ratios:
- LTV:CAC ratio: target > 3:1
- CAC payback period: CAC / monthly gross profit per customer
- Contribution margin: revenue - variable costs per unit
- Magic number: net new ARR / prior quarter S&M spend
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.

unit-economics is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed yesterday), licensed MIT. It adds 55 tokens to every session and 870 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-21.
