The /context command output frequently overlaps with other terminal output (diff views, MCP tool lists, etc.), making it unreadable. This has been happening consistently over the past ~10 days.

Root Cause

The /context command output frequently overlaps with other terminal output (diff views, MCP tool lists, etc.), making it unreadable. This has been happening consistently over the past ~10 days.

Description

The /context command output frequently overlaps with other terminal output (diff views, MCP tool lists, etc.), making it unreadable. This has been happening consistently over the past ~10 days.

Environment

Claude Code version: Latest (as of 2026-04-16)
Terminal: macOS native Terminal.app (no recent updates to terminal emulator — issue is on Claude Code side)
OS: macOS (Darwin 25.2.0, Apple Silicon)
Model: claude-opus-4-6[1m]

Steps to Reproduce

Run a session with multiple tool calls (MCP tools, git operations, etc.)
Run /context to check token usage
The output renders with overlapping text — MCP tool names, diff hunks, and context stats bleed into each other

Expected Behavior

/context output should render cleanly without overlapping other content.

Actual Behavior

Text from different output sections (diff views, MCP tool lists, context stats) overlap and become unreadable. See screenshots below.

Screenshots

Screenshot 1 — Diff output overlapping with /context and MCP tool list

The left side shows diff hunks ("Added 47 lines", WORK_LOG content) while the right side shows MCP tool names, creating an unreadable mess.

Screenshot 2 — Continued overlap

MCP tool list continues to overlap with other UI elements (sidebar labels like /wl, Del, Bas, Fla> appear on the left margin).

Notes

The terminal emulator has not been updated recently — this is a Claude Code rendering regression
Started approximately 10 days ago (around early April 2026)
Happens across multiple sessions, not a one-off

extent analysis

TL;DR

The issue can likely be mitigated by adjusting the rendering settings or output formatting of the /context command to prevent overlap with other terminal output.

Guidance

Review the Claude Code documentation for any options to customize the output of the /context command, such as adjusting the width or formatting of the output.
Consider using a different terminal emulator or adjusting the settings of the native Terminal.app to see if the issue is specific to the current configuration.
Investigate if there are any recent changes to the Claude Code version (as of 2026-04-16) that may have introduced this rendering regression.
Check if there are any known issues or open tickets related to rendering or output formatting in the Claude Code project.

Example

No specific code snippet can be provided without more information on the Claude Code API or command syntax.

Notes

The issue seems to be specific to the Claude Code rendering, and adjusting the output formatting or using a different terminal emulator may help mitigate the problem. However, without more information on the Claude Code version or configuration, it's difficult to provide a more specific solution.

Recommendation

Apply a workaround by adjusting the rendering settings or output formatting of the /context command, as it is likely that this will resolve the issue without requiring an upgrade to a fixed version.
