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 | $0.00038 | $0.01212 |
| Opus 5 | $0.00019 | $0.00606 |
| Sonnet 5 | $0.00008 | $0.00242 |
| Haiku 4.5 | $0.00004 | $0.00121 |
Grade A, and why
breaking-into-product 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.

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Breaking Into Product Management
Strategically navigate the competitive path to your first product management role.
Help the user with breaking into product management using insights from 11 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Assess role fit - Help the user evaluate if the daily realities of product management align with their motivations and natural tendencies.
- Identify the optimal path - Determine whether internal transfer, APM programs, or joining an early-stage startup is the most viable route based on their current context.
- Build a product track record - Guide the user on how to accumulate product-adjacent experience and social capital in their current role.
- Master the interview process - Provide frameworks for product sense, analytical, and execution-style interview questions.
Core Principles
Prioritize Internal Mobility
Annie Pearl: "I think there's really two paths. I think one is more formal in nature. There are associate product manager programs out there and many scaled companies, Google, Meta. All have APM programs that you can formally apply to."
The most effective way to break into the role is through internal transfers or formal APM programs at companies where you have already built trust.
Build or Sell First
Kevin Yien: "So for me, the sort of foundational three are going to be engineer, designer or salesperson. I think sales also gets not a bad rep, but a misrepresented reputation in tech where all they care about is quota, it's just about numbers, et cetera. In reality, the best salespeople are the best listeners, the best people at understanding the problem that the customer is having and then translating that into what you can do for them."
Gaining experience in roles that directly build or sell the product provides a necessary foundation for understanding how to convert potential into customer value.
Get a Seat on the Rocket Ship
Naomi Gleit: "I ended up going, sort of the analogy, I went to the second floor most days after work, asked if there were any projects that I could help out with. It was very early days. There was always more to do than people to do it. And so eventually I picked up a few projects, helping with program management, giving my product feedback, and by the time that I actually applied formally to be a product manager, I had been doing the job voluntarily, almost informally for a few months."
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.

breaking-into-product is a skill published in the GitHub repository RefoundAI/lenny-skills (1,323 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 1,212 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.
