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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00029 | $0.01536 |
| Opus 5 | $0.00015 | $0.00768 |
| Sonnet 5 | $0.00006 | $0.00307 |
| Haiku 4.5 | $0.00003 | $0.00154 |
Grade A, and why
team-culture 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building High-Performing Team Culture
Establish a culture of ownership, transparency, and intensity to drive long-term product success.
Help the user with building high-performing team culture using insights from 26 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Audit Cultural DNA - Help the leader analyze their current team dynamics and founder strengths to identify the inherent traits that define their culture.
- Define Actionable Values - Guide the user in drafting team values that include specific behavioral trade-offs rather than generic aspirational statements.
- Design Team Rituals - Suggest specific rituals for building trust, sharing work, and celebrating wins based on the team's specific remote or in-person setup.
- Diagnose Intensity Gaps - Assist the leader in identifying where organizational velocity or accountability is slipping and provide scripts for correcting those teams.
Core Principles
Results Over Popularity
Alisa Cohn: "They're trying now to be the leader who everyone loves, but what really needs to happen very often is, we need to drive towards results. This employee continuing to not really do a great job at their job, you don't want to push them because you don't want to upset them. You don't want to give them difficult feedback, so you're just going to keep hoping it works out. Ultimately, that leads to the demise of your company."
High-performing leaders must prioritize organizational results and performance standards over the desire to be liked by every individual. Avoiding difficult feedback to preserve popularity ultimately jeopardizes the long-term survival of the company.
Radical Business Transparency
Daniel Lereya: "We really have an approach of very radical transparency about everything. Before we went public, we actually shared every bit of information with our employees. Instead of demoralizing people, I think that this is something that gives them a sense of deep partnership."
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.
