Lenny Skills is a collection of product-management and engineering workflows for Claude Code and other AI agents, covering areas such as strategy, research, planning, shipping, growth, and hiring. Each skill gives an agent specialized guidance, frameworks, checklists, or templates for product work, and the catalogue contains many of these skills.
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 | $0.00033 | $0.01660 |
| Opus 5 | $0.00016 | $0.00830 |
| Sonnet 5 | $0.00007 | $0.00332 |
| Haiku 4.5 | $0.00003 | $0.00166 |
Grade A, and why
user-onboarding-activation 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User Onboarding and Activation
Bridge the gap between initial signup and realized value to maximize long-term retention.
Help the user with user onboarding and activation using insights from 15 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Define milestones - Help the user identify a data-backed activation metric that correlates with long-term retention.
- Audit the funnel - Identify high-friction steps or human-mediated gates that prevent users from seeing the product immediately.
- Apply behavioral design - Suggest psychological nudges like forced choice or the goal gradient effect to increase completion rates.
- Design for personas - Tailor the onboarding flow based on whether the user is an individual builder, a collaborator, or a financial buyer.
Core Principles
Onboarding is the highest leverage growth area
Adam Fishman: "Onboarding is the only part of your product experience that a hundred percent of people are ever going to touch. Good luck getting a hundred percent feature adoption of anything else in your product, right? But onboarding is the thing that you have to go through in order to use the product. It's also the first opportunity that you have as a company to deliver on the promise that you made out in the marketplace."
Since 100 percent of users experience the onboarding flow, any improvement here has a compounding effect on every subsequent stage of the funnel.
Design for the lazy, vain, and selfish user
Anuj Rathi: "So there's very interesting insight that I heard from Scott Belsky from Adobe, and then now, he's doing very interesting stuff, and that stayed with me which was you have to think about users on modern internet consumers having three attributes. So they are lazy, they are vain, and they're selfish."
Assume users have limited attention and want immediate personal benefit; the product must deliver a wow moment quickly to overcome entrenched habits.
Drive toward a single high-value action
Kristen Berman: "We worked with one medical on how to increase setting doctor's appointments right away during the onboarding, and that worked and drove it up by 20%."
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.

user-onboarding-activation is a skill published in the GitHub repository RefoundAI/lenny-skills (1,318 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 1,660 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 2026-09-03.
