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 | $0.01593 |
| Opus 5 | $0.00015 | $0.00796 |
| Sonnet 5 | $0.00006 | $0.00319 |
| Haiku 4.5 | $0.00003 | $0.00159 |
Grade A, and why
planning-cadence 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planning Cadence Optimization
Align long-term strategy with short-term execution through structured, tiered planning rituals.
Help the user with planning cadence optimization using insights from 13 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Audit Cadence - Evaluate if your current planning frequency matches your company size and market volatility.
- Design Resolution - Determine which horizons require granular project detail and which should remain high-level strategic themes.
- Select Framework - Choose between W, M, or rolling cycles based on your organization's need for top-down versus bottom-up input.
- Refine Rituals - Implement weekly checkpoints to bridge the gap between quarterly goals and the immediate actions required to move metrics.
Core Principles
Strategy Before Rituals
Shreyas Doshi Live: "And the interesting I found is that because I had a real product strategy, not one of those fake ones, a real product strategy that I had gotten alignment on with everybody, my planning for this major product for Stripe took me like three days."
Efficient planning is a byproduct of having a real, pre-aligned product strategy rather than just completing bureaucratic rituals.
Weekly Momentum Over Deadlines
Christina Wodtke: "I would say, 'What am I doing this week to get closer to our goals?' If you could answer that question, you could give up all the OKR stuff, but if you just asked the question, 'What are we doing this week to get closer to our strategic goals, our longer term goals?' That is the very heart of it..."
Shift focus from distant deadlines to the immediate actions required this week to ensure current tasks move you toward strategic objectives.
Standardize for Variance Reduction
Eeke de Milliano: "Process, by definition, is variance reducing. You're introducing it, because you worry that the variance in your org is too high. You want people to sort of meet a certain standard. And the cost of that is obviously, while you are reducing the standard and bringing folks up to the average, you're also bringing other folks down to the average."
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.

planning-cadence is a skill published in the GitHub repository RefoundAI/lenny-skills (1,318 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,593 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.
