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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.02420 |
| Opus 5 | $0.00018 | $0.01210 |
| Sonnet 5 | $0.00007 | $0.00484 |
| Haiku 4.5 | $0.00004 | $0.00242 |
Grade A, and why
business-adventures-analysis-brooks 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 13d 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
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Business Adventures Analysis — Skill (John Brooks)
Knowledge source: Business Adventures by John Brooks.
Architecture: Orchestrator + 6 subskills. The main SKILL.md routes the user query; subskills execute the diagnostic workflows and own their reference IDs.

Skill Purpose
Use this skill to apply John Brooks's Business Adventures as a diagnostic framework for corporate failures, market panics, product launches, governance breakdowns, regulatory risk, fraud, innovation, and financial culture.
The skill does not summarize the book or predict the future by analogy. It maps a live business situation to recurring Brooks patterns: panic, hubris, communication failure, incentive drift, regulatory lag, product-market mismatch, and institutional fragility.
Core Principle
Human nature is the constant; institutions are the variable. Identify the repeating human pattern first, then examine how structure, incentives, rules, timing, and information flow amplify it.
Workflow Inventory
| Workflow | User question pattern | Inputs | Steps | Output | Should be subskill? |
|---|---|---|---|---|---|
| Failure diagnosis | "Why did this company, product, or strategy fail?" | Company/product, timeline, market context, decisions | Pattern map, decision chain, warning signals, preventable actions | Primary failure pattern and decision correction | Yes |
| Market panic analysis | "What is happening in this crash?" | Trigger, price moves, liquidity, media, forced sellers | Panic phase, technical amplifiers, stabilizers, uncertainty | Panic diagnosis and stabilizer map | Yes |
| Regulatory risk review | "Is this practice risky?" | Practice, disclosure, materiality, enforcement context | Materiality, public usability, tolerated-practice risk, rule-change trigger | Risk level and action | Yes |
| Product and innovation review | "Will this launch or innovation work?" | Product, customers, incumbents, distribution, research | Timing test, differentiation, incumbent blind spots, commercialization | Stop/redesign/accelerate/monitor recommendation | Yes |
| Governance accountability | "Is management handling this well?" | Board, incentives, crisis response, shareholder/stakeholder power | Formal power vs real consequences, incentives, accountability | Governance diagnosis | Yes |
| Fraud and institutional fragility | "How exposed is this system?" | Trust mechanism, counterparties, collateral, disclosure, losses | Hidden exposure, responsibility transfer, contagion path, controls | Fragility map and safeguards | Yes |

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.

business-adventures-analysis-brooks is a skill published in the GitHub repository simbajigege/book2skills (163 stars, last pushed 17d ago), licensed MIT. It adds 36 tokens to every session and 2,420 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.
