<pre />

Native tool execution intercept callback receiving canonical context JSON.

`context_json` contains `tool_name`, `args`, and nullable `tool_call_id` fields. A successful callback must set `out_outcome_json` to canonical [`ToolExecutionInterceptOutcome`](/reference/api/rust-library-reference/nemo-relay-plugin/struct-toolexecutioninterceptoutcome) JSON allocated through the host.
