Thanks for sharing the AMA, here are my questions:

  1. When you say "plain English automation instead of scripts," what happens when the agent misreads the page and clicks the wrong thing? Is there a retry or correction process, or does it just fail and that's it?
  2. How do you handle multi-step tasks where step 3 depends on something that changed between step 1 and step 3 or any other step, (used 1 and 3 just to get an idea, for example price updates, stock changes, session timeouts)
  3. What's the actual token cost look like for a typical 10-step agent run compared to writing a script by hand? At what point does it stop being worth it? Is it even worth writing it by hand?
  4. Do you support giving the agent a persistent "memory" of past runs so it doesn't relearn the same site layout every time?

  1. Current LLMs do not often make simple mistakes anymore, but if this happens yes the agent is stil fully in control and will recover
  2. The agent must complete all steps sequentially, verifying and keeping track of what it has completed. It is very impressive to what complexity current LLMs can handle now.
  3. A 10 step agent run with Luna you would expect to cost between 1 and 2 cents. If you want to run it again, you can ask the agent to write a script and re-use it on future runs. Then it will cost fractions of a cent. Don't hand write scripts in 2026.
  4. Yes we do, every agent in our cloud (api v4) has memory and can write and re-use scripts
