used tool
- CURIE:
gmeow:usedTool - IRI: https://blackcatinformatics.ca/gmeow/usedTool
- Category: property
- Defined by:
gmeow:slices/agentic - Box roles: RBox role (What is this?)
The tool that was called — a SoftwareAgent (an MCP tool, a search service, a code runner). Deliberately no Tool subclass: tool-ness is the role the agent plays in this call event, not an identity. Functional: one tool per call; a multi-tool turn is several ToolCalls.
Structure
Property shape: object property; gmeow:ToolCall -> gmeow:SoftwareAgent; functional
Practical Pattern
Use gmeow:usedTool from gmeow:ToolCall to gmeow:SoftwareAgent when the relationship itself belongs in the native GMEOW graph.
Example Snippets
