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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 48 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00057 | $0.01031 |
| Opus 5 | $0.00028 | $0.00515 |
| Sonnet 5 | $0.00011 | $0.00206 |
| Haiku 4.5 | $0.00006 | $0.00103 |
Grade A, and why
pentest-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 5d 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.

pentest-bizlogic
Advisory for business-logic vulnerabilities automated scans miss. Requires human analysis — this skill provides methodology + checklists.
Triggers
- "race condition test"
- "price manipulation"
- "workflow bypass"
- "coupon abuse"
- "refund flow vulnerability"
- "checkout flow analysis"
Common Bizlogic Categories
| Category | Example | Test |
|---|---|---|
| Price manipulation | Change the cart price in the POST body | Negative price, decimal precision, currency mismatch |
| Race condition | 5 parallel /api/redeem-coupon | Use the coupon 2x via a race |
| Workflow bypass | POST directly to step 3 (skip 1, 2) | State machine skipping |
| Coupon abuse | Single-use coupon across multiple accounts | No coupon scope |
| Refund abuse | Refund > original | No server-side total recalc |
| Account recovery | Username + date of birth -> reset link | Missing out-of-band factor |
| Voucher generation | Voucher code predictable (sequential) | Insufficient entropy |
| MFA bypass | login_step=2 POST directly -> token | Insecure server state |
| Privilege grant | User A invites User B -> B becomes admin | Role inheritance flaw |
Race Condition Test Pattern
# 5 parallel requests — functional reuse test
for i in {1..5}; do
curl -X POST https://<target>/api/redeem -H "Authorization: Bearer $TOKEN" \
-d '{"coupon":"SAVE10"}' &
done
wait
# Expectation: 1 success + 4 errors
# Vulnerability: 5 successes -> coupon stacking via a race
More controlled: Turbo Intruder (Burp), Repeater Group "Send in parallel" (Burp Pro 2023+).
Price Manipulation Checklist
- Is the cart price client-side (change it in the POST body, does the server accept it)
- Currency code swap (USD -> EUR, server doesn't recalc the total)
- Decimal precision (price: 1.99 -> 1.99999, which version is saved)
- Negative quantity (qty: -1 -> negative invoice, credit issued)
- Discount > 100% (coupon 110% discount, payable negative)
- Promo + sale price (two discounts stacked, is it forbidden)
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.

pentest-bizlogic is a skill published in the GitHub repository fatihkan/badi (7 stars, last pushed 4d ago), licensed MIT. It adds 57 tokens to every session and 1,031 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 2026-09-06.
