Root Cause

In a recent version of Claude Code, tool call outputs (Read, Edit, Bash, etc.) are rendered fully expanded by default in the transcript. This makes long sessions with many file reads very hard to navigate — scrolling back through past turns becomes painful because every tool output takes significant vertical space.

In a recent version of Claude Code, tool call outputs (Read, Edit, Bash, etc.) are rendered fully expanded by default in the transcript. This makes long sessions with many file reads very hard to navigate — scrolling back through past turns becomes painful because every tool output takes significant vertical space.

Two things suggest this is a recent change or A/B experiment:

  • On a different laptop with the same account, tool outputs are still collapsed by default.
  • The behavior changed on this machine without a config change on my side.

Tried without success:

  • verbose: false in ~/.claude/settings.json
  • viewMode: "default"
  • DISABLE_TELEMETRY=1 (in case it was a Statsig gate)

Request: a user-level setting to collapse tool outputs by default (e.g. toolOutputCollapsed: true or extending viewMode with a compact option), and/or honoring the existing verbose: false for this rendering.

Use case: solo founder running many long Claude Code sessions per day; expanded tool outputs make session review and scrollback significantly slower.

TL;DR

The issue can be potentially mitigated by introducing a user-level setting to collapse tool outputs by default.

Guidance

  • Investigate the difference in settings or environment variables between the two laptops to identify any discrepancies that might be causing the behavior change.
  • Consider reaching out to the Claude Code support team to inquire about any recent changes or A/B experiments that might be affecting the tool output rendering.
  • Review the ~/.claude/settings.json file for any other settings that might be influencing the tool output behavior, even if not directly related to verbose or viewMode.
  • If possible, test the behavior with a different account or on a different machine to see if the issue is specific to the current setup.

Example

No code snippet is provided as the issue is related to configuration and settings rather than code.

Notes

The issue seems to be related to a recent change or A/B experiment, and the exact cause is unclear. The suggested user-level setting to collapse tool outputs by default might not be currently available, and the existing verbose: false setting does not seem to be honored.

Recommendation

Apply workaround: Introduce a feature request or reach out to the Claude Code support team to inquire about the possibility of adding a user-level setting to collapse tool outputs by default, as this seems to be the most direct way to address the issue.
