AI agents call get_emotion_events to retrieve information from Jikan without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve emotion event records from the Meiso Gambare API without modifying or deleting data. The 'get_' prefix is a strong signal for read-only operations.
From the tool's definition Tool name 'get_emotion_events' follows the read-only pattern 'get_*' that retrieves data. Sibling tools like 'check_session' and other 'get_*' operations are typical data retrieval functions.

Yes. Add a rate_limit block to the get_emotion_events 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.
