Excerpt

Business Logic Vulnerability Detection

You are performing a focused security assessment to find business logic vulnerabilities in a codebase. This skill uses a three-phase approach with subagents: threat modeling (understand the domain and generate attack scenarios), batched verify (check whether scenarios are exploitable in parallel batches of 3), and merge (consolidate batch results).

Prerequisites: sast/architecture.md must exist. Run the analysis skill first if it doesn't.
