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 | $0.00028 | $0.02059 |
| Opus 5 | $0.00014 | $0.01030 |
| Sonnet 5 | $0.00006 | $0.00412 |
| Haiku 4.5 | $0.00003 | $0.00206 |
Grade A, and why
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 8d 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 Five Forces
Overview
Industry-level competitive analysis developed by Michael Porter. Measures the structural forces that determine how much profit potential an industry holds. Use it before entering a market, launching a product, or stress-testing a competitive position.
THREAT OF NEW ENTRANTS

SUPPLIER POWER ───── INDUSTRY RIVALRY ───── BUYER POWER

THREAT OF SUBSTITUTES
High force intensity = low industry attractiveness (profits get competed away). Low force intensity = pricing power and sustained margins.
The Five Forces
1 — Threat of New Entrants
How easy is it for new competitors to enter?
- Raises threat: low capital requirements, no IP protection, commodity product, low switching costs
- Lowers threat: patents, regulatory licenses, economies of scale, strong brand loyalty, network effects, high upfront investment
- Rate: Low / Medium / High
2 — Supplier Power
How much leverage do suppliers have over your costs?
- Raises power: few suppliers, no substitutes for inputs, suppliers can forward-integrate, your industry is a small customer for them
- Lowers power: many competing suppliers, you can backward-integrate, inputs are commodities, switching costs are low
- Rate: Low / Medium / High
3 — Buyer Power
How much leverage do customers have over your prices?
- Raises power: few large customers, product is undifferentiated, buyers can backward-integrate, buyers are price-sensitive, low switching costs
- Lowers power: fragmented customer base, high switching costs, product is essential or highly differentiated
- Rate: Low / Medium / High
4 — Threat of Substitutes
How likely are customers to switch to a different solution?
- Raises threat: substitute meets same need at lower price or higher convenience, low switching costs, buyers are willing to experiment
- Lowers threat: no close substitute exists, substitute requires behavior change, strong brand allegiance to your product
- Rate: Low / Medium / High
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.

porters-five-forces is a skill published in the GitHub repository tupe12334/instinct (1 stars, last pushed 22d ago), licensed MIT. It adds 28 tokens to every session and 2,059 once invoked, about $0.0001 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 2026-08-31.
Other skills, from other repositories
thinking-theory-of-constraints
When throughput or latency is pipeline-limited, identify the single binding constraint and exploit, subordinate, elevate, then recheck—ignore non-constraints.
thinking-lindy-effect
Use when longevity of a non-perishable option matters. Treat survival duration as a remaining-life prior, then check domain drift before favoring the proven.
thinking-kepner-tregoe
Use when a selective defect needs IS/IS-NOT difference analysis or a consequential option choice needs must/want weighting and adverse-consequence comparison.
alive:demo
Generate a believable, lived-in ALIVE world from a free-text persona description (custom path) or a deterministic sandbox preset. Routes the create/list/activate/deactivate/delete/status surface and orchestrates the 5-stage subagent generation pipeline.
alive:session-history
Revive sessions (quick or heavy), browse, and search — 'what happened recently?', 'find the session where we discussed X', 'revive yesterday's session'. For single-session recall and multi-session browsing. If the human needs to merge multiple sessions into one working context or detect conflicts between parallel…
alive:world
The human doesn't know what to work on, or wants to see everything at once. They need the big picture — what's active, what's stale, what needs attention. Renders a live world view grouped by ALIVE domain, then routes to open, tidy, find, history, or map.
