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 | $0.00055 | $0.01530 |
| Opus 5 | $0.00028 | $0.00765 |
| Sonnet 5 | $0.00011 | $0.00306 |
| Haiku 4.5 | $0.00006 | $0.00153 |
Grade A, and why
hunt-bizlogic scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
4. **Repetition / limits / logic race.** Apply a coupon twice, redeem a gift card twice, exceed a per-account limit. When the limit is a check-then-act with no lock, fire a **small concurrent burst** at the single endpoi How it starts

Hunt: Business Logic
Assumes hunt-core for the scope gate, two-account rule, confirmation gate, enumeration limits, stop conditions, wiki protocol, FIND output, and Deadends. Do not re-derive any of that here.

No scanner finds these
This is the top-paying bug class and the one with zero scanner coverage - it is all manual reasoning. Find an assumption the developer made and break it: that steps happen in order, that values are positive, that the client cannot change a field, that an action cannot be repeated. Map the intended workflow first (read the feature, the happy path, every state transition); the flaw is always the gap between that and what the server actually enforces.
Attack surface - rank before testing
Money and state-machine endpoints pay; cosmetic ones do not. Work them in this order:
- Checkout / payment - client-supplied price, total, tax, currency, shipping, anywhere the server should recompute a value and instead trusts it.
- Refund / coupon / gift card / store credit - re-redemption, stacking, negative amounts, a refund exceeding the purchase.
- Multi-step workflows - checkout, transfer, signup, KYC, password reset, subscription: skip, replay, or reorder a step.
- Quantity / price fields - negative, zero, overflow, decimal and rounding.
- State transitions - an action valid only in one state performed from another (ship before pay, use before verify).
Methodology
Setup: two accounts per hunt-core where the flaw is cross-actor; one account suffices for pure value or state tampering. Drive the load-bearing requests through Burp Repeater for operator visibility.
- Map the flow. Enumerate every step and state of the target feature. Note each parameter and which server check governs it. The flaw is a check the client can reach around.
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.
- 12d ago First seen · 94 lines · 55 tokens per session scan A a758f7a6a84b
hunt-bizlogic is a skill published in the GitHub repository Encod3d-Sec/TORCH (322 stars, last pushed 11d ago), licensed MIT. It adds 55 tokens to every session and 1,530 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
