Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.01258 |
| Opus 5 | $0.00014 | $0.00629 |
| Sonnet 5 | $0.00006 | $0.00252 |
| Haiku 4.5 | $0.00003 | $0.00126 |
Grade A, and why
Business Logic Vulnerabilities — Complete Deep Dive 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.

Business Logic Vulnerabilities — Complete Deep Dive
Deep-Dive Lab Playbook — Every PortSwigger lab variant with exact payloads, bypass techniques, and zero-day extensions. 🟢 Apprentice 🟡 Practitioner 🔴 Expert
When to Use
- BSCP certification prep
- Real-world bug bounty hunting
- Building exploitation chains
- Understanding bypass techniques
Prerequisites
- Burp Suite Professional
- Burp Collaborator / interactsh
- Browser with proxy configured
Workflow
Phase 1: Reconnaissance
- Identify input vectors, parameters, and application behavior.
Phase 2: Exploitation
- Apply standard lab payloads.
Phase 3: Zero-Day Escalation
- Fuzz filters, bypass WAFs, and chain with other vulns.
Lab Playbooks
Lab 1: Excessive client-side trust 🟢 APPRENTICE
Intercept purchase request, change price=100 to price=1. Server trusts client-sent price.
Lab 2: High-level logic vulnerability 🟡 PRACTITIONER
Set quantity=-1 → negative total. Or quantity so high it wraps around (integer overflow) → price becomes negative.
Lab 3: Inconsistent security controls 🟡 PRACTITIONER
Register with attacker email, then change email to @dontwannacry.com to get admin access.
Lab 4: Flawed business rules 🟡 PRACTITIONER
Alternate between two coupon codes: NEWCUST5 → SIGNUP30 → NEWCUST5 → SIGNUP30. System only blocks consecutive duplicates.
Lab 5: Low-level logic flaw 🟡 PRACTITIONER
Add quantity until price integer overflows past MAX_INT → wraps to negative. Add enough to bring total to small positive number.
Lab 6: Exceptional input handling 🟡 PRACTITIONER
255+ char email: [email protected] — email truncated to 255 chars, domain becomes @dontwannacry.com.
Lab 7: Weak isolation on dual-use endpoint 🟡 PRACTITIONER
Password change endpoint: remove current-password parameter entirely. Server doesn't require it for admin functionality.
Lab 8: Insufficient workflow validation 🟡 PRACTITIONER
After adding items, skip to order confirmation: POST /cart/order-confirmation without going through payment.
What ships with it
1 file 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.

Business Logic Vulnerabilities — Complete Deep Dive is a skill published in the GitHub repository akashrpatil/awesome-offensive-security-skills (5 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 28 tokens to every session and 1,258 once invoked, about $0.0001 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 2026-08-31.
