Macro artifact 

artifact!() { /* proc-macro */ }

Writes an artifact value via the Output on Context

Expands to context.output().artifact(...).await.expect("event channel closed"), where context resolves to the local variable in the calling function’s scope. Unlike message! and detail!, this macro does not use format! — it takes an expression that implements Display, Serialize, and Debug. This is the macro equivalent of Output::artifact.

The macro must be called from an async function because the core Output methods are async.

Examples

use clawless::prelude::*;

#[command]
pub async fn count(args: CountArgs, context: Context) -> CommandResult {
    let count = WordCount { words: 42 };
    artifact!(count);
    Ok(())
}
