What makes a weekly competitor brief useful enough to act on?

I build EvidentSignal. One question behind the product is how to turn a competitor update into a decision instead of another link in a feed.

A useful manual brief can separate five things:

1. Observation: what actually changed.

2. Evidence: the original source and date.

3. Implication: why it might matter to a specific decision.

4. Uncertainty: what still needs checking.

5. Next action: an owner and a concrete follow-up.

For a pricing change, for example, check currency, billing period, eligibility and included features before calling it a price increase.

We published an editable template that can be used without an account: https://evidentsignal.com/templates/competitor-brief/

What field would you add, and which competitor updates usually turn out to be noise?
