org-designHelp users design high-performing product and engineering organizations by choosing the right reporting models, team sizes, and cross-functional partnerships.
Org Design is an agent skill from RefoundAI/lenny-skills. Help users design high-performing product and engineering organizations by choosing the right reporting models, team sizes, and cross-functional partnerships. It focuses on reducing friction and maximizing ownership through structural clarity.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/artifacts.md` and `references/guest-insights.md`).
The repository describes itself as: 86 product management skills from Lenny's Podcast for Claude Code and AI agents. Hiring, user research, strategy, shipping, and more. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 13598cc. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Org Design loads about 2.3k tokens when it runs, and up to ~43k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 1,290 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Help the user with organizational design for product and engineering using insights from 27 guests and posts across Lenny's Podcast and Newsletter.
Bill Carr: "Let's create teams that can stand alone, where there's a single leader and the cross- functional resources that they need are all either directly report to them or are dedicated to them. So they don't necessarily have to be a straight line direct report. In Amazon's case, for the most part it was. There were some dotted line, but it could be all straight line, it could be all dotted line, it could be a mix of the two."
Move away from shifting resources between tasks toward a program orientation where teams own a specific customer area indefinitely. This empowers single-threaded leaders to take full ownership of long-term outcomes.
Claire Vo: "I'm using CPTO for short code of running product and engineering design functionally together. There should be no debates over what's best for product or what's best for engineering, what's best for design speed. What is best for the organization?"
Consolidating product, engineering, and design under one leader eliminates functional silos. This alignment stops internal debates and optimizes for overall organizational speed over individual department goals.
Dhanji R. Prasanna: "So all engineers report into one single team now, all designers report into one single team and there's single head of engineering, single head of design, et cetera. And so that was the big transformation that we made, and that meant we could really drive forward AI, we could drive forward platform and just technical depth generally."
Transitioning to a functional structure helps a company align on singular technical strategies. It allows for standardized engineering levels and policies that drive excellence across the entire department.
Heidi Helfand: "I really like it when there's transparency in reorgs. There's a story in my book from Christian Lima at Spotify about how they reorged a large infrastructure team. They visualized it on whiteboards and brought people over to the whiteboards to see the future team structure that the leaders wanted and they got input into the design."
Maintain transparency during reorganizations by visualizing proposed structures on public whiteboards. Involving employees early helps identify structural errors and increases engagement with the new mission.
Karri Saarinen: "We actually don't have much PMs in the company. We only have one and we can talk about more about it. One of the things I think that happens is when you build a team and you start creating these very specific roles for everything I think that often the PM can be the ones figuring things out and making decisions and guiding the team, but they're not the ones building the feature."
Eliminating dedicated PMs for every team can increase ownership among those actually building the product. Distributing management tasks to engineers and designers fosters higher attention to detail.
Varun Mohan: "I want the company to almost be like this dehydrated entity. Every hire is like a little bit of water, and we only go back and hire someone when we're back to being dehydrated."
Treat every new hire as a scarce resource and wait until the team is truly underwater before adding headcount. This prevents organizational bloat and ensures every role is vital for project survival.
Sachin Monga: "The teams aren't oriented around product surfaces. We don't have a team that's like the app team or a team that's like the dashboard team or the podcasting team. We have teams that are oriented around customers and solving bit of a timeless customer problem."
Define teams by the specific customer group they serve rather than ephemeral feature surfaces. This creates a more durable structure where each team has its own dedicated cross-functional resources.

Run `npx skills add RefoundAI/lenny-skills --skill org-design -a claude-code`. Or copy the skill folder (skills/org-design in RefoundAI/lenny-skills) into .claude/skills/org-design in your project. Claude Code loads it when a task matches its description.
Run `npx skills add RefoundAI/lenny-skills --skill org-design -a codex`. Or copy the skill folder (skills/org-design in RefoundAI/lenny-skills) into .agents/skills/org-design in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add RefoundAI/lenny-skills --skill org-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/org-design, .gemini/skills/org-design, .github/skills/org-design and .opencode/skills/org-design in your project.
SKILL.md names no scripts, command-line tools or credentials: Org Design is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Org Design is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 41k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Org Design: React Performance (affaan-m/ECC, 275k stars), Performance Profiler (alirezarezvani/claude-skills, 28k stars), Agent Performance Optimizer (ruvnet/ruflo, 74k stars) and Handsontable Performance Testing (handsontable/handsontable, 22k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
