Why rabin_karp_search is rated Low
The Rabin-Karp algorithm is a string matching algorithm that locates pattern instances in text. This is a read-only operation that retrieves or identifies data without modifying, deleting, or executing code. No financial, destructive, or code execution capabilities are implied. Severity is low because misuse of a search function has minimal impact; an AI agent cannot cause harm by finding text patterns.
From the tool's definition Tool description states 'Find all occurrences of a pattern in text' — a pure search/query operation with no side effects.
