[BUG] Custom commands are being duplicated e.g create 2 custom command files, 4 new commands appear in Claude Code

Environment

• Claude CLI version: 1.0.55 (Claude Code)
• Operating System: MacOS 15.5 (Silicon)
• Terminal: Warp (but happens in every other terminal on my machine)

Bug Description

I have created a custom command that I have placed inside the /commands directory, for some reason it is appearing twice when I log into Claude within the terminal (see screenshots)

Steps to Reproduce

1. Create any new custom command in the ./claude/commands directory (Ensure Claude Code is not active) e.g 'feature.md'
2. Launch Claude Code from any terminal
3. Press the forward slash / to see all commands
4. The newly added command appears twice in the listing at the very top

Expected Behavior

I have only created one command so would only expect to see one command in the Claude Code terminal

Actual Behavior

I always see the number of custom commands duplicated in the Claude Code terminal, so if I create 5 custom command files, this appears as 10 commands in the terminal

Additional Context

Screenshots below

I have created a new 'load' custom command markdown file, but it appears twice in the listing in the screenshot
