I haven't tried your exact task, of course, but I've found a lot of success in using JSON structured output (in strict mode), and decomposing the response into more fields than you would otherwise think useful. And making those fields highly specific.

For example: make the suggestion output an object with multiple fields, naming one of them `concise_suggestion`. And make sure to take advantage of the `description` field.

For people not already using structured output, both OpenAI and Anthropic consoles have a pretty good JSON schema generator (give prompt, get schema). I'd suggest using one of those as a starting point.
