Before you write
Be specific about the failure
"It hallucinates sometimes" is hard to act on. "It invents line items on scanned invoices with two columns" tells me where to look before the call even starts.
You don't need a spec
A paragraph and a link to the feature is enough. If I need more I'll ask on the call rather than send you a questionnaire.
I'll say no if it's a no
If this isn't my problem — or you don't have the problem you think you have — you'll hear that instead of a proposal.
