AI agents call precedents_get to retrieve information from Legalize without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns legal precedent data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that accesses a legal database via GitHub REST API. No destructive, financial, or execution-based actions are possible.
From the tool's definition Tool name 'precedents_get' and description '판례 전문을 조회합니다' (retrieves full text of legal precedents) indicate a query/retrieval operation with no modification or side effects.

"version": "1",
"default": "deny",
"tools": {
"precedents_get": {}
}
