SKILL.md

Web Application Logic

Test for logic flaws and application-specific vulnerabilities that automated scanners miss.

Techniques

Type	Key Vectors
Business Logic	Workflow bypass, price manipulation, feature abuse
Race Conditions	TOCTOU, limit bypass, double-spend, parallel requests
Access Control	IDOR, horizontal/vertical privilege escalation, forced browsing
Cache Poisoning	Unkeyed headers/parameters, fat GET, response splitting
Cache Deception	Path confusion, static extension tricks, normalization
Info Disclosure	Error messages, debug endpoints, source code, metadata

Workflow

Map application workflows and business rules
Identify state-dependent operations and trust boundaries
Test logic assumptions with edge cases and race conditions
Verify access control across user roles
Document impact with PoC demonstrations
