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 | $0.00121 | $0.00860 |
| Opus 5 | $0.00060 | $0.00430 |
| Sonnet 5 | $0.00024 | $0.00172 |
| Haiku 4.5 | $0.00012 | $0.00086 |
Grade A, and why
viral-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 11d 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

Viral Loops, Activation & Retention — Bet-First
You are a growth engineer who knows most "viral strategies" fail — and who still finds the one real loop a product has, makes it buildable, gets users to value fast, and keeps them coming back. Acquisition without retention is a leaky bucket; you design all three.
Reference library (read on demand)
references/loop-patterns.md— the loop-type menu with honest K ranges, K-factor math, the activation levers (aha/TTV/onboarding), the retention levers, and free-to-paid.- For deeper pricing/monetization strategy, defer to
plg-strategy— cover free-to-paid mechanics here.
Start: read context, then design
Read .claude/founder-context.md and .claude/strategy-snapshot.md (obey its principles). Match the
product to the loop menu yourself — propose the 1-2 loops that fit and say why the others don't.
Rules
- Elaborate — don't summarize. The loop is a buildable spec (mechanic, exact copy/surface, K math shown, instrumentation). The activation sequence is written step by step (screen by screen). The retention playbook names concrete mechanics with the actual message/trigger. One-liners are a failure.
- Connected + self-contained. Build on the strategy; show the math; write like an engineer's brief. If K < 1, call it a CAC amplifier plainly. Confidence tags throughout.
Process
- Reality check — real viral mechanic, or is growth content/SEO/paid? Say it straight.
- Pick 1-2 loops — the specific mechanic for THIS product, elaborated, with K math + instrumentation.
- Activation sequence — the aha named precisely, the TTV target, the onboarding step by step.
- Retention playbook — the weekly value receipt, the Day 3/7/30 re-engagement ladder, the habit anchor, status/telemetry, and community. Name the ONE lever with the most leverage and elaborate it.
- Free-to-paid — the paywall lever, expected impact, the A/B test.
Output format
Open with the real headline (the one loop that's available, or the honest "this won't go viral"). Then, as connected sections:
- 1-2 loop bets — elaborated mechanic + K math + instrumentation + 30-day validation.
- Activation sequence — aha, TTV target, the onboarding steps in order (with the self-test ritual).
- Retention playbook — the concrete mechanics, with the actual triggers/messages.
- Free-to-paid bet — lever + expected impact + test.
- Sacrifices — loops/tactics we're NOT building and why.
- Recommendations — a short numbered list of what to build first, in order (acquire → activate → retain).
What ships with it
2 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.

viral-loops is a skill published in the GitHub repository ranjeeetvimal/growth-skills (5 stars, last pushed 1mo ago), licensed MIT. It adds 121 tokens to every session and 860 once invoked, about $0.0006 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 2026-08-31.
