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 | $0.00034 | $0.01319 |
| Opus 5 | $0.00017 | $0.00660 |
| Sonnet 5 | $0.00007 | $0.00264 |
| Haiku 4.5 | $0.00003 | $0.00132 |
Grade A, and why
founder-sales 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 12d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Founder-Led Sales
Master the art of personally selling your product to build trust and find product-market fit.
Help the user with founder-led sales using insights from 6 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Assess Readiness - Determine if you have enough product validation to start direct selling or if you are hiring a salesperson too early.
- Refine the Pitch - Help draft and iterate on the founder-led narrative and value proposition based on subject matter expertise.
- Sales Motion Design - Design a high-volume discovery and closing process tailored for early-stage feedback loops.
- Overcome Psychological Barriers - Address common hurdles like the fear of asking for money or managing introversion in a sales context.
Core Principles
Leverage Founder Status
Jen Abel: "And founder led sales is really, really, really important because in the very, very, very early days, when there is no brand equity, when there is no marketing engine running, when there is limited to no reference ability, the founder is the product, right? Because the product is still, could be abstract, could be an MVP or in it's really early formation. So the founder is the product."
Use your unique subject matter expertise and novel vision as the primary driver for sales because early products cannot yet sell themselves on features alone.
Treat Sales as a Discipline
Pete Kazanjy: "The thing that I just like to encourage founders and product managers and what have you is just don't be afraid of sales. There's a lot of people out there who would love to tell you a story that it's magical or like, "Oh, you've got to be a born seller," things like that and it's really not."
View sales as a learnable, operational discipline consisting of measurable behaviors rather than an innate talent or magical gift.
Make the Direct Financial Ask
Jason M Lemkin: "Work up your courage, and find how to ask for next steps and money. What would it take, Lenny? How can we get going on Riverside? What would it take?"
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.

founder-sales is a skill published in the GitHub repository RefoundAI/lenny-skills (1,321 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 1,319 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.

llama-cpp
Run LLM inference with llama.cpp on CPU, Apple Silicon, AMD/Intel GPUs, or NVIDIA — plus GGUF model conversion and quantization (2–8 bit with K-quants and imatrix). Covers CLI, Python bindings, OpenAI-compatible server, and Ollama/LM Studio integration. Use for edge deployment, M1/M2/M3/M4 Macs, CUDA-less…
systematic-debugging
Use when encountering any bug, test failure, or unexpected behavior. 4-phase root cause investigation — NO fixes without understanding the problem first.
github-auth
Set up GitHub authentication for the agent using git (universally available) or the gh CLI. Covers HTTPS tokens, SSH keys, credential helpers, and gh auth — with a detection flow to pick the right method automatically.
ideation
Generate project ideas through creative constraints. Use when the user says 'I want to build something', 'give me a project idea', 'I'm bored', 'what should I make', 'inspire me', or any variant of 'I have tools but no direction'. Works for code, art, hardware, writing, tools, and anything that can be made.
notion
Notion API for creating and managing pages, databases, and blocks via curl. Search, create, update, and query Notion workspaces directly from the terminal.
ocr-and-documents
Extract text from PDFs and scanned documents. Use webextract for remote URLs, pymupdf for local text-based PDFs, marker-pdf for OCR/scanned docs. For DOCX use python-docx, for PPTX see the powerpoint skill.
