What's Wrong?

Description

When running /insights in Claude Code CLI on Windows, the report path is displayed with a missing backslash before .claude:

Displayed: C:\Users\tomge.claude\usage-data\report.html
Expected: C:\Users\tomge\.claude\usage-data\report.html

The \. sequence is being interpreted as a markdown escape, stripping the backslash from the rendered output.

Steps to Reproduce

1. Open Claude Code CLI on Windows
2. Run /insights
3. Observe the file path in the output — the \ before .claude is missing

Expected Behavior

The full path should render with the backslash intact: C:\Users\<username>\.claude\usage-data\report.html

Environment

• OS: Windows 11 (10.0.26200)
• Terminal: Git Bash
• Claude Code: Latest (as of 2026-04-02)

Root Cause

The markdown renderer treats \. as an escape sequence and strips the backslash. Windows file paths containing \.claude are affected because the dot after the backslash triggers this behavior.

Related Issues

• #18996 — EDITOR env var strips backslash before .claude folder (same symptom, different trigger)
• #12677 — Markdown renderer interprets _, *, \ as tokens in non-markdown content

Suggested Fix

Escape backslashes in file paths before passing them to the markdown renderer and / or wrap file paths in inline code blocks (backticks) which preserve literal characters and / or correct the concatenation of the userprofile variable with the report path.

What Should Happen?

Claude CLI should be amended to correctly reflect the path of the report
