Thanks.

What happens right now when the workflow fails mid-way? Do you ensure atomicity or durable execution?

[samuelbrashears]

We do a fixed number of retries, including redoing any AI arguments. We've thought about making it atomic/more durable -- it's tricky, given that most steps interact with external systems e.g. Google Sheets, and while not typically "destructive" (Google Sheets has version history), undo-ing is often difficult.

[thoughtlede]

Yeah. Rollbacks or reruns are hard when dealing with external systems. Actions need to be idempotent for reruns to work.

One thing you may focus on is making workflows more durable: Checkpointing and sending to users summaries of last checkpoints when things fail.

The last thing you want a non-tech user (your target customer) is to figure out what’s the state of a failed workflow.
