AI agents call get_schedules to retrieve information from Datagsm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves academic calendar data (NEIS-linked academic schedules) without modifying, deleting, or executing external operations. It is a straightforward read operation with no permanent effects or financial implications. Low severity due to limited sensitivity of calendar/schedule information and read-only nature.
From the tool's definition Tool name 'get_schedules' and description '조회합니다' (retrieve/query) and 'confirm' indicate data retrieval. The description specifies querying academic schedules and events for specific dates/periods with no mention of modifications, deletions, or side effects.

get_schedules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_schedules rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
