<pre />

Wrap or replace tool execution.

A tool execution intercept receives the tool name, the current argument payload, and the continuation representing the rest of the chain.

## Parameters

* First argument: Tool name associated with the execution.
* Second argument: Current JSON argument payload.
* Third argument: Continuation for the remaining execution chain.

## Returns

A future resolving to the canonical tool execution outcome, containing the tool result and any pending lifecycle marks produced by this intercept.

## Errors

The future resolves to an error when the intercept or remaining execution chain fails.

## Aliased Type

```rust
pub struct ToolExecutionFn { /* private fields */ }
```
