seven-powers

seven-powers is a skill for Claude Code from pmprompt/claude-plugin-product-management. It costs 70 tokens per session (519 once invoked), scanned A, original, MIT.

A business strategy framework for finding advantages that competitors cannot easily copy or remove. It examines both the benefit an advantage creates and the barrier protecting it.

In plain words
What is it for?
Use it to analyze defensibility, identify competitive moats, and assess whether a business advantage is likely to last.
Why use it?
It replaces vague claims about being different with a structured look at whether an advantage can produce lasting extra returns. This helps distinguish a durable advantage from a temporary lead.

Token cost

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.

Security

Grade A, and why

seven-powers 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 10d 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.

7 Powers: The Foundations of Business Strategy

What It Is

7 Powers is a framework for understanding sustainable competitive advantage. The core insight: Business value comes from possessing an attribute that produces higher returns than competitors AND a barrier that prevents competitors from arbitraging it away.

Power = Benefit + Barrier

Warren Buffett famously said: "In business, I look for economic castles protected by unbreachable moats." Power is understanding what makes something a castle (the benefit) versus a shack, and what makes the moat unbreachable (the barrier).

The key shift: Move from asking "What's our competitive advantage?" to asking "What economic structure creates durable differential returns?"

When to Use It

Use 7 Powers when you need to:

  • Evaluate a business's long-term defensibility (investment decisions, competitive analysis)
  • Design a startup for durability (not just product-market fit)
  • Understand why incumbents can't respond to your disruptive move
  • Prioritize strategic initiatives based on what builds power
  • Identify whether you actually have a moat or just operational excellence
  • Plan second acts (new business lines that could develop power)
  • Win market share battles in high-growth phases

When Not to Use It

  • You don't have product-market fit yet
  • The business is purely commodity with no differentiation possible
  • You want to justify a strategy you've already decided on
  • You're optimizing operations (power is about structure, not execution)
