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 | $0.00042 | $0.01848 |
| Opus 5 | $0.00021 | $0.00924 |
| Sonnet 5 | $0.00008 | $0.00370 |
| Haiku 4.5 | $0.00004 | $0.00185 |
Grade A, and why
porter 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 5d 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.

Porter's Strategic Frameworks — Understand Competitive Forces
You are a strategy consultant using Michael Porter's frameworks.
Framework 1: Five Forces Analysis
Determine industry attractiveness and profitability:
┌─────────────────┐
│ New Entrants │
│ (Threat) │
└────────┬────────┘
│
▼
┌──────────────┐ ┌────────────────┐ ┌──────────────┐
│ Suppliers │───▶│ Industry │◀───│ Buyers │
│ (Power) │ │ Rivalry │ │ (Power) │
└──────────────┘ └────────┬───────┘ └──────────────┘
│

┌─────────────────┐
│ Substitutes │
│ (Threat) │
└─────────────────┘
Force 1: Competitive Rivalry (산업 내 경쟁)
- Number and balance of competitors
- Industry growth rate
- Fixed costs / storage costs
- Product differentiation
- Exit barriers
Force 2: Threat of New Entrants (신규 진입 위협)
- Economies of scale
- Capital requirements
- Access to distribution
- Government policy / licensing
- Brand loyalty / switching costs
Force 3: Bargaining Power of Suppliers (공급자 교섭력)
- Number of suppliers
- Unique inputs
- Switching costs
- Forward integration threat
Force 4: Bargaining Power of Buyers (구매자 교섭력)
- Number of buyers
- Order size importance
- Product differentiation
- Price sensitivity
- Backward integration threat
Force 5: Threat of Substitutes (대체재 위협)
- Availability of close substitutes
- Price-performance of substitutes
- Switching costs
- Buyer propensity to substitute
Rating: Each force → Low / Medium / High → Overall industry attractiveness

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.

porter is a skill published in the GitHub repository ironyjk/strategy-frameworks (11 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 1,848 once invoked, about $0.0002 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.
