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 | $0.00078 | $0.03055 |
| Opus 5 | $0.00039 | $0.01528 |
| Sonnet 5 | $0.00016 | $0.00611 |
| Haiku 4.5 | $0.00008 | $0.00305 |
Grade A, and why
unit-economics-analysis 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 9d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unit Economics Analysis
Model whether a defined customer cohort produces enough retained contribution and cash to support its acquisition and service system. Treat CAC, LTV:CAC, margin, and payback as versioned outputs of compatible entity, cohort, cost, value, timing, maturity, source, and uncertainty contracts, not intrinsic business properties.
Read unit-economics-contract.md before accepting customer, cohort, cost, value, channel, or accounting evidence. Read costs-and-cac.md before calculating media, direct, fully loaded, attributed, incremental, blended, or marginal CAC. Read value-payback-and-compatibility.md before using revenue, gross profit, contribution, cash, LTV, LTV:CAC, or payback. Read portfolio-decisions-and-governance.md before comparing cohorts, spend bands, products, channels, segments, markets, freemium paths, or marketplace sides. Read output-contract.md before delivery. Use playbook-sources.md to cite the pinned Growth Playbook basis.
Select One Mode
| Mode | Use |
|---|---|
audit |
Inspect an existing CAC, LTV:CAC, margin, payback, return, channel-economics, or unit-economics claim |
model |
Calculate supplied compatible economics or create a calculation-ready model with bounded scenarios |
portfolio |
Compare compatible cohorts, products, channels, segments, markets, spend bands, motions, or scenarios under one decision |
Name one primary mode, decision, owner, customer and payer entity, acquisition cohort, product and offer, market, channel or source, acquisition event, cost basis, value basis, observed and forecast horizons, evidence cutoff, model version, review date, and external-action boundary. Public pages can verify visible products, packages, prices, and claims. They cannot establish private spend, customers, retention, costs, contribution, cash, CAC, LTV, payback, incrementality, or forecast quality.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-analysis is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 16d ago), licensed MIT. It adds 78 tokens to every session and 3,055 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
