Built a plan on an assumption marked "unconfirmed"

Research

Situation

Building a plan for an activity from research results. The research had marked the most important point "unconfirmed."

What the AI did

It had read that "unconfirmed" but built the entire plan without resolving it. When the person asked about it and the AI checked, the assumption turned out to be different from what the plan assumed.

How to ask next time (the operator's example)

"Before building the plan, list the assumptions marked 'unconfirmed.' If the most important one is unconfirmed, check it first."

One question to ask

Is the plan resting on any unconfirmed assumption?

Check it yourself

Before the plan is written, search the research notes yourself for "unconfirmed," "unknown," "TBD," and "assume," and mark which plan steps rest on each hit.
