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 | $0.00031 | $0.01040 |
| Opus 5 | $0.00015 | $0.00520 |
| Sonnet 5 | $0.00006 | $0.00208 |
| Haiku 4.5 | $0.00003 | $0.00104 |
Grade A, and why
pm-career-growth 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 13d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PM Career Growth
Transition from task-executor to high-impact product leader by mastering influence, ownership, and strategic foresight.
Help the user with pm career growth using insights from 43 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Define the roadmap - Help the user treat their career as a product by defining success metrics and a multi-year growth strategy.
- Identify ownership gaps - Guide the user to find high-impact, neglected problems in their organization that they can take responsibility for.
- Audit influence skills - Evaluate the user's current relationship-building and communication styles to identify blockers to senior-level trust.
- Prepare for transitions - Provide tactical advice for navigating promotions, new domain pivots, or moving into executive leadership.
Core Principles
Accept Total Responsibility
Ben Horowitz: "What I was trying to get out in Good Product Manager, Bad Product Manager, was the job is fundamentally a leadership job. And it's a tricky leadership job because nobody is actually reporting to you."
Product leadership is defined by driving results without formal authority. You must accept total responsibility for whether the product works, regardless of team structure.
Prioritize Creative Velocity
Amjad Masad: "Typically, you're bottlenecked where your ideas are not fitting in because they need to be made and they need to be made quickly. Now, you open up that bottleneck. So now actually making things is a lot easier. Actually, you become limited by how fast you can generate ideas."
In the AI era, the bottleneck shifts from technical implementation to how quickly you can generate and refine high-impact ideas and product architectures.
Shift to Proactive Leadership
Ethan Evans 2.0: "So in the newsletter we did together, I wrote about how over time, you go from asking your manager, 'How can I help?' To suggesting to your manager, 'These are some things I see that seem like they need to be done. Would you like me to do them?' To just seeing what needs to be done and sort of keeping your leader in the loop and saying, 'Hey, I noticed that we have this problem. I fixed it. I noticed we have this opportunity. I've started program against it.'"
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.

pm-career-growth is a skill published in the GitHub repository RefoundAI/lenny-skills (1,321 stars, last pushed 1mo ago), licensed MIT. It adds 31 tokens to every session and 1,040 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 2026-08-30.
