Problem Statement

I asked Claude:
what will prevent things like this one: … +31 lines (ctrl+o to expand)
the response:
Unfortunately, there's no setting to disable that.

The "… +N lines (ctrl+o to expand)" collapsing is a hardcoded UI behavior in Claude Code's terminal renderer — it's
not configurable.

Your options:

1. Press Ctrl+O to expand the collapsed section inline when you see it
2. Use --verbose flag — gives more detailed logging but won't prevent the collapsing
3. Request the feature — report it at https://github.com/anthropics/claude-code/issues as a request for a setting like "collapseToolOutput": false

It's a reasonable feature request — a toggle in settings.json to control the collapse threshold or disable it entirely.

Proposed Solution

a toggle in settings.json to control the collapse threshold or disable it entirely
a setting like "collapseToolOutput": false (default true)
