contagious
Engineer word-of-mouth and virality using the STEPPS framework (Social Currency, Triggers, Emotion, Public, Practical Value, Stories). Use when the user mentions "go viral", "word of mouth", "shareable content", "social currency", "why people share", "referral program", "nobody is sharing it", or "make this spread". Also trigger when designing shareable features, crafting social campaigns, or building products that spread through peer recommendation. Covers environmental triggers and high-arousal emotional content. For sticky messaging, see made-to-stick. For persuasion tactics, see influence-
npx skills add wondelai/skills --skill contagious --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Word-of-Mouth & Virality Framework A framework for engineering word-of-mouth and making products, ideas, and content contagious, based on Jonah Berger's research into why things catch on. Use it to design shareability into products, campaigns, and content instead of hoping for luck. ## Core Principle **Virality is not born — it is engineered.** Products spread because they were designed — consciously or not — to be shared. Only 7% of word-of-mouth happens online; the other 93% happens in offline conversations, so virality is about the psychology of sharing, not social media mechanics. Those psychological patterns are predictable and can be engineered into anything using the STEPPS framework. See: [references/word-of-mouth.md](references/word-of-mouth.md) when the brief over-indexes on social media — it makes the offline-vs-online case, lists conversation triggers, and gives a WOM measurement/audit method. ## Scoring **Goal: 10/10.** Score each of the six STEPPS drivers (the six Quick Diagnostic rows) — **0** absent, **1** present but weak, **2** strong and deliberate — for a raw 0-12, then map: 11-12 -> 10, 9-10 -> 8-9, 6-8 -> 6-7, 3-5 -> 4-5, 0-2 -> <=3.

What does the contagious skill do?
Engineer word-of-mouth and virality using the STEPPS framework (Social Currency, Triggers, Emotion, Public, Practical Value, Stories). Use when the user mentions "go viral", "word of mouth", "shareable content", "social currency", "why people share", "referral program", "nobody is sharing it", or "make this spread". Also trigger when designing shareable features, crafting social campaigns, or building products that spread through peer recommendation.

How do I install it?
Run `npx skills add wondelai/skills --skill contagious --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From wondelai/skills, a repository with 1,835 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
