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 | $0.00076 | $0.01587 |
| Opus 5 | $0.00038 | $0.00794 |
| Sonnet 5 | $0.00015 | $0.00317 |
| Haiku 4.5 | $0.00008 | $0.00159 |
Grade A, and why
"biz-porters-five-forces" 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 9d 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.
This is a copy
94% identical to biz-porters-five-forces — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Porter's Five Forces Analysis
Overview
Porter's Five Forces assesses industry-level competitive dynamics by examining five structural forces that determine profitability. Unlike SWOT (company-level) or PESTEL (macro-level), this framework operates at the industry level — it answers "is this industry attractive?" not "is this company strong?"
When to Use
Trigger conditions:
- User asks whether an industry or market is attractive or profitable
- User evaluates whether to enter a new market or industry
- User needs to understand competitive dynamics beyond direct competitors
- User mentions "barriers to entry", "supplier power", or "industry structure"
When NOT to use:
- For company-specific strengths/weaknesses → use SWOT
- For macro-environment scanning → use PESTEL
- For product portfolio decisions → use BCG Matrix
Framework
IRON LAW: Industry-Level, Not Company-Level
Each force describes the INDUSTRY structure, not a specific company's position.
"Our supplier raised prices" is a company event.
"Suppliers in this industry are concentrated with few alternatives" is an industry force.
NEVER analyze a single company's situation — analyze the structural conditions
all players in the industry face.
IRON LAW: All Five Forces, Every Time
Analyze ALL five forces before drawing conclusions. Skipping forces produces
misleading assessments. An industry with low rivalry but high substitute threat
is very different from one with low rivalry and no substitutes.
Step 1: Define the Industry Boundary
Before analyzing forces, clearly define:
- What industry? Be specific — "food delivery platforms in Taiwan" not "tech"
- Geographic scope: global, regional, or national
- Time horizon: current state or projected 3-5 years
Getting the boundary wrong invalidates the entire analysis.
Step 2: Analyze Each Force
Rate each force as High / Medium / Low pressure on industry profitability:
1. Threat of New Entrants — How easy is it for new players to enter?
- Capital requirements, economies of scale, brand loyalty, regulatory barriers
- Access to distribution channels, switching costs, incumbents' response
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
