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 | $0.00041 | $0.00279 |
| Opus 5 | $0.00020 | $0.00139 |
| Sonnet 5 | $0.00008 | $0.00056 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
business-logic-vuln 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 11d 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
100% identical to business-logic-vuln — 0 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.
What it actually says
Business Logic Router
This is the routing entry point for business-logic and state-machine issues.
When to Use
- The target involves coupons, inventory, payment, approvals, quotas, invites, trials, or state transitions
- The issue is not parser-level; it is about when checks happen and which business conditions are checked
- You suspect race conditions, workflow bypass, price tampering, negative values, stacked discounts, or multi-step flaws
Skill Map
Recommended Flow
- First map key business states and one-time actions
- Then check for check-then-act windows, sequence dependencies, or missing cross-step authorization
- If the chain depends on APIs, uploads, or object permissions, return to the corresponding router skill to complete the path

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.
