B3/5.0
Scored across 1 tool
Disambiguation5/5
With only one tool, there is no possibility of confusion or overlap between tools. The tool's purpose is singular and clear.
Naming Consistency5/5
The single tool follows a clear verb_noun pattern (create_event), and with no other tools to compare, consistency is inherently perfect.
Tool Count2/5
One tool is too few for a Google Calendar server, as it lacks essential operations like listing, updating, or deleting events, making it severely limited for typical calendar management tasks.
Completeness1/5
The tool set is severely incomplete; it only allows event creation without any way to view, modify, or manage existing events, leaving major gaps in calendar functionality.
