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 | $0.00042 | $0.00915 |
| Opus 5 | $0.00021 | $0.00458 |
| Sonnet 5 | $0.00008 | $0.00183 |
| Haiku 4.5 | $0.00004 | $0.00092 |
Grade A, and why
designing-growth-loops 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.

Designing Growth Loops
Help the user design effective growth loops using frameworks from 54 product leaders who have built viral and product-led growth engines at companies from Dropbox to LinkedIn to Calendly.
How to Help
When the user asks for help with growth loops:
- Identify the loop type - Determine if they need viral, paid, content, or product-led acquisition loops
- Assess prerequisites - Check if they have the LTV, network effects, or product stickiness to support the loop
- Find the natural sharing moment - Help them identify where users would naturally want to bring others in
- Design for compounding - Ensure the loop feeds back into itself for sustainable growth
Core Principles
One dominant loop matters most
Luc Levesque: "It's usually just one loop that you need to get right. Most successful companies scale primarily through one dominant, well-executed growth loop." Focus on identifying and dominating one primary channel before diversifying.
Viral growth is a learnable science
Nikita Bier: "With certainty, if you're good at your job, you can make an app grow and go viral. Over the years of building all these apps, I've accrued all these growth hacks that still nobody knows about." Develop a library of growth tactics based on platform-specific mechanisms.
LTV unlocks paid loops
Yuriy Timen: "If you have really healthy LTVs, then there is a big opportunity to play paid and lean into paid growth loops." Calculate if single-player LTVs are high enough to support sustainable paid acquisition.
Product-led acquisition has zero marginal cost
Julian Shapiro: "By me trying to use PayPal in its everyday intention, I'm automatically enticing someone else to become a PayPal customer." PLA is the most scalable channel because it's entirely within the company's control.
Innovation over optimization in fast markets
Elena Verna: "I feel like only 30 to 40% of what I've learned transfers here because we need to invest in such bigger bets and innovate and create new growth loops." In fast-moving AI categories, shift from 95% optimization to 95% innovation.
What ships with it
1 file 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.

designing-growth-loops is a skill published in the GitHub repository cnfeat/top-pm-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 915 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.
