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 | $0.00034 | $0.05403 |
| Opus 5 | $0.00017 | $0.02701 |
| Sonnet 5 | $0.00007 | $0.01081 |
| Haiku 4.5 | $0.00003 | $0.00540 |
Grade A, and why
acquisition-channel-advisor 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 8d 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 — 644 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Guide product managers through evaluating whether to scale, test, or kill an acquisition channel based on unit economics (CAC, LTV, payback), customer quality (retention, NRR), and scalability (magic number, volume potential). Use this to make data-driven go-to-market decisions and optimize channel mix for sustainable growth.
This is not a channel strategy framework—it's a financial lens for channel evaluation that helps you avoid scaling unprofitable channels or killing channels with fixable problems. Use when deciding how to allocate marketing budget across channels.
Key Concepts
The Channel Evaluation Framework
A systematic approach to evaluate acquisition channels:
-
Unit Economics — What does it cost to acquire, and what's the return?
- CAC (Customer Acquisition Cost)
- LTV (Lifetime Value)
- LTV:CAC ratio
- Payback period
-
Customer Quality — Do customers from this channel stick around and expand?
- Cohort retention rate (by channel)
- Churn rate (by channel)
- NRR (Net Revenue Retention by channel)
- Expansion rate
-
Scalability — Can this channel sustain growth at the volume you need?
- Magic Number (S&M efficiency)
- Addressable volume (TAM of channel)
- Saturation risk (diminishing returns)
- CAC trend (increasing, stable, decreasing)
-
Strategic Fit — Does this channel align with your go-to-market strategy?
- Customer segment match (SMB vs. enterprise)
- Sales motion compatibility (PLG vs. sales-led)
- Brand positioning alignment
Decision Matrix
| LTV:CAC | Payback | Customer Quality | Scalability | Decision |
|---|---|---|---|---|
| >3:1 | <12mo | Good retention | High volume | Scale aggressively |
| 2-3:1 | 12-18mo | Average retention | Medium volume | Test & optimize |
| <2:1 | >18mo | Poor retention | Low volume | Kill or fix |
Anti-Patterns (What This Is NOT)
- Not vanity metrics: "We got 10,000 signups!" means nothing if they churn in 30 days
- Not CAC-only thinking: Low CAC with terrible retention is worse than high CAC with great retention
- Not ignoring payback: 5:1 LTV:CAC with 36-month payback is a cash trap
- Not scaling broken channels: Pouring money into inefficient channels accelerates failure
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.

acquisition-channel-advisor is a skill published in the GitHub repository getcrew44/crew44 (359 stars, last pushed 2mo ago), licensed MIT. It adds 34 tokens to every session and 5,403 once invoked, about $0.0002 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 2026-08-30.
