Tool Call

• CURIE: gmeow:ToolCall
• IRI: https://blackcatinformatics.ca/gmeow/ToolCall
• Category: class
• Defined by: gmeow:slices/agentic
• Box roles: TBox role (What is this?)

One invocation of a tool by an agent: the tool agent (gmeow:usedTool), the requesting model invocation when known (gmeow:calledByInvocation), and the verbatim arguments/result payloads. The agent's actions join the same provenance graph as its claims — an entity the call produced links back via gmeow:wasGeneratedBy (no forward output property, Principle 5), so 'which tool, called by which invocation, with what arguments?' is answerable after the fact. The ModelInvocation idiom one level down.

Structure

Subclass of: gmeow:Activity

Practical Pattern

Use gmeow:ToolCall as a specialized kind of gmeow:Activity. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

• An assistant's MCP store_claim call: the ToolCall records the tool agent, the verbatim JSON arguments, and the stored claim's id as the result payload; the claim itself links back with gmeow:wasGeneratedBy.
