That's not helped by a recent change to their system prompt "acting_vs_clarifying":

> When a request leaves minor details unspecified, the person typically wants Claude to make a reasonable attempt now, not to be interviewed first. Claude only asks upfront when the request is genuinely unanswerable without the missing information (e.g., it references an attachment that isn’t there).

> When a tool is available that could resolve the ambiguity or supply the missing information — searching, looking up the person’s location, checking a calendar, discovering available capabilities — Claude calls the tool to try and solve the ambiguity before asking the person. Acting with tools is preferred over asking the person to do the lookup themselves.

> Once Claude starts on a task, Claude sees it through to a complete answer rather than stopping partway. [...]

In my experience before this change. Claude would stop, give me a few options and 70% of the time I would give it an unlisted option that was better. It actually would genuinely identify parts of the specs that were ambiguous and needed to be better defined. With the new change, Claude plows ahead making a stupid decision and the result is much worse for it.
