What it does

Referrals Word Of Mouth is an agent skill from RefoundAI/lenny-skills. Help users build sustainable growth engines by transitioning from accidental word-of-mouth to structured referral programs and viral product loops.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/artifacts.md` and `references/guest-insights.md`).

It sits in Marketing & SEO, covering Referral and retention marketing. The repository describes itself as: 86 product management skills from Lenny's Podcast for Claude Code and AI agents. Hiring, user research, strategy, shipping, and more. The licence is MIT.

When your agent uses it

  • Tasks that involve Referral and retention marketing

Example prompts

  • “/referrals-word-of-mouth”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Assess readiness - Determine if the product has sufficient organic word-of-mouth and retention to support a formal referral program.
  2. Identify viral loops - Map out the product natural social actions to choose the right type of virality such as word-of-mouth, invitation…
  3. Design incentives - Craft a reward structure that balances selfish, altruistic, and FOMO motivations within CAC limits.
  4. Optimize and scale - Measure the referral funnel and place touchpoints throughout the user journey to maximize discoverability.

What it can do on your machine

Read from SKILL.md and the folder at commit 13598cc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Referrals Word Of Mouth loads about 1.8k tokens when it runs, and up to ~20k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 1,017 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~20k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Referrals and Word-of-Mouth

Turn user satisfaction into a high-leverage growth engine through organic advocacy and structured referral loops.

Help the user with referrals and word-of-mouth using insights from 13 guests and posts across Lenny's Podcast and Newsletter.

How to Help

  1. Assess readiness - Determine if the product has sufficient organic word-of-mouth and retention to support a formal referral program.
  2. Identify viral loops - Map out the product natural social actions to choose the right type of virality such as word-of-mouth, invitation, or experiential.
  3. Design incentives - Craft a reward structure that balances selfish, altruistic, and FOMO motivations within CAC limits.
  4. Optimize and scale - Measure the referral funnel and place touchpoints throughout the user journey to maximize discoverability.

Core Principles

Remarkableness as a Core Value

Rahul Vohra: "It is word of mouth. It is the virality you can't measure that isn't a mechanic that isn't in a feature. It is when one user spontaneously tells another user about your product."

Sustainable growth is earned through extraordinary quality and delight that makes a product worthy of spontaneous attention rather than temporary gimmicks.

The 10x Performance Threshold

Nilan Peiris: "But to get to recommendation, you're going to blow your user socks off. You have to give them an experience they didn't know was previously possible. And when you are in that place of doing something that no one has ever done before, that's when you get it."

To trigger true word-of-mouth, the product must be exponentially better than the status quo, typically by being significantly faster, cheaper, or easier to use.

Accelerate Existing Organic Growth

From "Building a referrals program": "The added incentive that a referral program offers simply adds fuel to an existing fire. I haven’t seen referrals work when there wasn’t strong existing WOM."

A referral program acts as an accelerator for existing interest. It should only be built once you verify that a majority of growth is already organic.

High-Value Milestone Incentives

From "Kickstarting supply in a labor marketplace": "Later, we had a two-sided referral program where if supply referred new supply, we would pay them $50 for each activated pro (after completing their first gig). If they referred a restaurant we would give them something like $300."

Structure referral payouts to occur only after the referred user reaches a clear activation milestone, such as completing their first transaction.

Product-Led Virality

Carilu Dietrich: "In order to get hypergrowth, you have to have organic, inbound, and viral word of mouth. You can't pay enough to grow at those rates and have a viable company."

Hypergrowth is driven by an amazing product experience that people are naturally excited to share, rather than unsustainable paid acquisition spend.

Community De-risking

Camille Ricketts: "In terms of how I think about what it actually is, it's when your community helps you achieve such ubiquity and such name recognition that it actually allows you to start moving upmarket into the enterprise. And I know that might be very specific to enterprise oriented companies, but that's how we defined it at Notion was the fact that so many people were talking about this, sharing what they had built about it, honestly starting businesses of their own around it to formalize the relationship with teams that I think it de-risked Notion as a choice for a lot of companies"

A passionate community creates brand ubiquity and user-generated social proof, which is critical for lowering perceived risk for new buyers.

Questions to Help Users

  • "What percentage of your current signups are coming from direct or organic search channels?"
  • "What is the core remarkable moment in your product that users would actually tell a friend about?"
  • "Is your product naturally multiplayer or does it provide more value when more people use it?"
  • "Have you identified the incentive plateau where increasing a referral reward no longer improves conversion?"
  • "How are you currently tracking 'How did you hear about us?' data during your onboarding?"
  • "Are your referral incentives aligned with a high-value user milestone or just a simple signup?"

Common Mistakes to Flag

  • Manufacturing virality from a mediocre product - If the core experience is not remarkable, synthetic loops and incentives will fail to create sustainable growth.
  • Misaligning referral incentives - Offering rewards that do not motivate users or that exceed the customer acquisition cost limits leads to inefficient spend.
  • Ignoring the supply side - Referral programs often provide more leverage on the supply side of a marketplace than the demand side, but are often overlooked.
  • Poor program discoverability - Burying the referral program in a settings menu instead of surfacing it at moments of high user satisfaction limits its volume.
