[BUG] running `/usage` triggers a different slash command.

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [x] Other: <!-- specify --> CLI on Windows 11, WSL Ubuntu.
• Claude CLI version: Claude CLI version 1.0.45
• Operating System: Windows 11, Ubuntu 24.04.2 LTS
• Terminal: bash

Bug Description

<!-- A clear and concise description of the bug -->
CC CLI (on Windows WSL) command got mapped to a different command.

Steps to Reproduce

Whenever I try /usage, it goes and runs /git-commit, which is totally unexpected.

Expected Behavior

<!-- What you expected to happen -->
I was hoping to see how far away from compacting (%age) I was so that I can decide whether to compact or keep going.

Actual Behavior

<!-- What actually happened -->
when I run /usage it ends up running a different command git-commit which is in my .claude/commands folder.

Additional Context

<!-- Add any other context about the problem here, such as screenshots, logs, etc. -->
Claude Code told me to report it here, with this message...

 I see you tried /help and /cost commands, and they work
  normally. But /usage is still triggering your git-commit
  command.

  This confirms it's specifically the /usage command that has
  the issue. Since /usage isn't a documented Claude Code
  command, it seems like Claude Code might be interpreting it
  as a custom command and somehow mapping it to your
  /git-commit command.

  This appears to be a bug in Claude Code's command parsing.
  You should report this to Claude Code support at
  https://github.com/anthropics/claude-code/issues since
  /usage shouldn't be triggering /git-commit.
