Struct ToolError 

pub struct ToolError {
    pub code: String,
    pub message: String,
}

A business-level failure: the tool ran and said “no” (e.g. “heading not found”). This is DATA carried inside the outcome, not an engine fault. Each surface decides its own presentation: the MCP adapter reports a failed invocation (isError: true with the {code, message} in structuredContent — A4); the CLI prints the error and keeps its exit semantics.

Fields

code: String

Stable machine code, e.g. "heading_not_found".

message: String

Human/agent-readable explanation.
