AI agents call get_district_events_simple to retrieve information from Tba without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves event information from The Blue Alliance (a FIRST Robotics Competition data service). The use of 'List' and the emphasis on 'reduced event fields' and being 'Lighter' confirm it is a read-only operation with no side effects. No data is created, modified, deleted, or executed—only fetched for display.
From the tool's definition Tool name 'get_district_events_simple' and description 'List events in an FRC district with reduced event fields' indicate a retrieval operation that returns data without modification.

get_district_events_simple 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_district_events_simple 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.
