What find_revisions does on Law Diff

AI agents call find_revisions to retrieve information from Law Diff without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why find_revisions needs a policy

This tool scans and queries an e-Gov database to retrieve revision IDs matching specified criteria (date range, law ID, or keyword). It is a read-only retrieval operation with no side effects. The low severity reflects minimal risk if misused by an AI agent, as it only exposes publicly available legal revision information without capability to modify, execute, or delete data.

From the tool's definition Tool description states it 'Scan[s] e-Gov updated-law lists' and 'find[s] revision IDs' — purely a search/lookup operation that retrieves metadata about law revisions. No modification, deletion, execution, or financial operations are involved.
