sast-businesslogic

sast-businesslogic is a skill for Claude Code, Codex from capture0x/YeepForge. It costs 110 tokens per session (4,713 once invoked), scanned A, original, no licence file.

A source-code review for business logic vulnerabilities: flaws in the rules that control prices, limits, permissions, or multi-step workflows. It models likely attack scenarios and checks whether the code can be misused.

In plain words
What is it for?
Use it to inspect payment and pricing rules, workflow steps, usage limits, and other domain-specific checks for bypasses.
Why use it?
It helps find ways to bypass application rules even when individual functions appear secure. Findings from several checks are combined into one review.

Token cost

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.

Security

Grade A, and why

sast-businesslogic 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 1mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
