A skill your agent uses when presenting information from external sources, citing research, or answering factual questions.
Help users identify sources of durable competitive power, evaluate market threats, and design products that are uniquely differentiated rather than just better versions of existing tools.

Competitive Strategy is an agent skill from RefoundAI/lenny-skills. Help users identify sources of durable competitive power, evaluate market threats, and design products that are uniquely differentiated rather than just better versions of existing tools.
Its SKILL.md is about 1.8k 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.
Competitive Strategy loads about 1.8k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 1,037 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 competitive strategy using insights from 24 guests and posts across Lenny's Podcast and Newsletter.
Bob Moesta: "And so when you start to realize that, jobs helps you see the true competitive set from what we call the demand side of the world as opposed to the competitive set from the supply side of the world, which is the technology or the underlying business model by how which we're making it."
True competition is defined by the customer's situational context and what they would use if your product did not exist. Shift from technical category analysis to demand-side analysis to see your real rivals.
Drew Houston: "Less than a year later, Google Photos launches. And not only does it provide a lot of the same value, but they also gave you free unlimited storage for life. And so, they just totally nuked our business model."
Treat major incumbent product launches as signals of market consolidation or shifts. Even if the immediate impact is low, these moves indicate where the market is heading and when a niche may become commoditized.
Hamilton Helmer: "So in a book there's a thing called power progression, which says there are... It tells over the cycle of a business, there are times when certain types of power are available and the converse of that is times when they're not available."
Startups should focus on moats that incumbents are unwilling to copy because doing so would damage their existing business model. Exclude branding and process power early on, as these are rarely available to new entrants.
Roger Martin: "You have to be either differentiated or low cost, there's no way to protect yourself if you're not one of those two."
Sustainable advantage requires a definitive choice between being the lowest-cost provider or being uniquely differentiated. Attempting to do both usually results in a lack of focus and market failure.
Richard Rumelt: "And my point in writing about David and Goliath was that the surprise that David is able to beat this giant warrior, and that's a strategy story. Strategy story is about discovered strength."
Competitive advantage often comes from identifying a unique internal strength that competitors have overlooked. Look for these asymmetries to create a surprise victory rather than fighting on the rival's terms.
Robby Stein: "Not every great thing is going to be invented by you. Facebook probably created the modern feed, but there's a feed for every single product. At the end of the day, you're just robbing your user base of the opportunity to have a better product."
When a competitor's innovation becomes a fundamental format that users expect, matching it is a service to your customers. Withholding proven improvements in the name of originality often does more harm than good.

Run `npx skills add RefoundAI/lenny-skills --skill competitive-strategy -a claude-code`. Or copy the skill folder (skills/competitive-strategy in RefoundAI/lenny-skills) into .claude/skills/competitive-strategy in your project. Claude Code loads it when a task matches its description.
Run `npx skills add RefoundAI/lenny-skills --skill competitive-strategy -a codex`. Or copy the skill folder (skills/competitive-strategy in RefoundAI/lenny-skills) into .agents/skills/competitive-strategy 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 competitive-strategy -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/competitive-strategy, .gemini/skills/competitive-strategy, .github/skills/competitive-strategy and .opencode/skills/competitive-strategy in your project.
SKILL.md names no scripts, command-line tools or credentials: Competitive Strategy 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.
Competitive Strategy is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.8k tokens (SKILL.md is roughly 7.3k 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 15k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Competitive Strategy: Source Evaluation (aiming-lab/MetaClaw, 3.5k stars), Arize Evaluator (github/awesome-copilot, 40k stars), Journal Of Power Sources (brycewang-stanford/Awesome-Journal-Skills, 1.2k stars) and LLM Evaluation (davila7/claude-code-templates, 32k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
