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.

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 | $0.00070 | $0.01045 |
| Opus 5 | $0.00035 | $0.00522 |
| Sonnet 5 | $0.00014 | $0.00209 |
| Haiku 4.5 | $0.00007 | $0.00104 |
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 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

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 (but DO think about which path tilts toward power)
- The business is purely commodity with no differentiation possible
- You want to justify a strategy you've already decided on (intellectual honesty required)
- You're optimizing operations (power is about structure, not execution)
Patterns
Detailed examples showing how to apply 7 Powers correctly. Each pattern shows a common mistake and the correct approach.
Critical (get these wrong and you've wasted your time)
| Pattern | What It Teaches |
|---|---|
| operational-excellence-not-power | Running faster on a treadmill isn't power — it can be mimicked |
| benefit-without-barrier | A castle without a moat gets stormed |
| network-effects-vs-network-economies | Having network effects doesn't mean you have power |
| power-timing | Different powers are available at different business stages |
| counter-positioning-window | Counter-positioning is your refuge from incumbents — but only early |

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.

seven-powers is a skill published in the GitHub repository wdavidturner/product-skills (20 stars, last pushed 7mo ago), licensed MIT. It adds 70 tokens to every session and 1,045 once invoked, about $0.0003 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.
