What it does

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.

Example prompts

  • “/competitive-strategy”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify demand-side competition - Help the user define their rivals based on customer situational context rather than technical categories.
  2. Audit structural power - Guide the user through identifying moats like counter-positioning, network effects, or switching costs.
  3. Clarify winning paths - Force a choice between being the lowest-cost provider or being uniquely differentiated to avoid being stuck in the…
  4. Assess incumbent vulnerability - Analyze true switching costs, including organizational politics and career stakes, to find openings.

What it can do on your machine

Read from SKILL.md and the folder at commit 13598cc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    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.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

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.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~17k

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.

Safety

Auto-check passed

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.

Competitive Strategy

Build durable moats and outmaneuver rivals by identifying structural power and customer-centric differentiation.

Help the user with competitive strategy using insights from 24 guests and posts across Lenny's Podcast and Newsletter.

How to Help

  1. Identify demand-side competition - Help the user define their rivals based on customer situational context rather than technical categories.
  2. Audit structural power - Guide the user through identifying moats like counter-positioning, network effects, or switching costs.
  3. Clarify winning paths - Force a choice between being the lowest-cost provider or being uniquely differentiated to avoid being stuck in the middle.
  4. Assess incumbent vulnerability - Analyze true switching costs, including organizational politics and career stakes, to find openings.

Core Principles

Define competition by customer context

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.

Monitor incumbent moves as market signals

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.

Prioritize counter-positioning for startups

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.

Choose between cost leadership and differentiation

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.

Exploit asymmetries as discovered strengths

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.

Adopt industry primitives as user-centricity

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.

Questions to Help Users

  • "What would your customers use to solve this problem if your product vanished tomorrow?"
  • "Which of the 7 Powers (like network effects or switching costs) are you intentionally building?"
  • "If an incumbent copied your main feature, what structural reason would prevent them from stealing your customers?"
  • "Are you competing to be the best version of a product or to be a unique alternative?"
  • "What are the non-technical reasons, such as internal politics or career risk, that keep users tied to your competitors?"
  • "What 'messy' operational challenges are you taking on that your competitors are avoiding?"

Common Mistakes to Flag

  • Copying features without context - Mimicking a competitor's UI or features ignores the underlying business rules and data models that actually create their moat.
  • Mistaking growth for power - Near-term growth can be bought with capital, but long-term viability requires structural barriers that prevent rivals from arbitrage.
  • Ignoring 'true' switching costs - Startups often underestimate the organizational inertia and emotional safety that keep buyers attached to clunky incumbent software.
  • Falling into the 'stuck in the middle' trap - Failing to commit to either cost leadership or clear differentiation leads to a muddled value proposition that satisfies no one.
