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 | $0.00030 | $0.01379 |
| Opus 5 | $0.00015 | $0.00690 |
| Sonnet 5 | $0.00006 | $0.00276 |
| Haiku 4.5 | $0.00003 | $0.00138 |
Grade A, and why
product-reviews 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Effective Product Reviews
Run rigorous alignment sessions that raise the quality bar and accelerate decision-making.
Help the user with effective product reviews using insights from 12 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Assess review culture - Evaluate current review formats and identify bottlenecks or gaps in quality standards.
- Select a framework - Recommend the appropriate review stage or template based on the project's complexity and lifecycle.
- Draft review materials - Assist in framing problem statements, mapping the option space, and preparing pre-read documents.
- Facilitate the session - Provide techniques for gauging sentiment, managing dissent, and capturing clear decisions.
Core Principles
Evaluate Frameworks, Not Solutions
From "How Figma builds product": "One thing I encourage for both is to first present the “option space”—it’s really powerful to have a framework that maps all possible solutions or problems and use that as a device to discuss high-level tradeoffs or philosophical differences."
High-quality decisions come from mapping the entire field of possible solutions rather than debating a single proposal in isolation.
Establish a Transparent Cadence
From "How Duolingo builds product": "Product review meetings happen every Tuesday and Thursday for a total of two hours. These two hours are divided into 20-minute slots that product teams sign up to present. The agenda of these meetings is product teams presenting their proposed product changes for the first 5 to 10 minutes and then reviewers asking questions and giving feedback for the rest of the time."
Recurring, short review slots prevent feedback bottlenecks and create a shared understanding of what constitutes quality across the organization.
Separate Problem from Solution
From "How Miro builds product": "Product reviews can focus on different stages of the product development lifecycle: P-Strat: long-term strategy and vision; P0: the opportunity and problem that we want to pursue; P1: the proposed solution; P2: what we launched and how it’s performing."
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.

product-reviews is a skill published in the GitHub repository RefoundAI/lenny-skills (1,321 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,379 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.
