🚨 HELP! Slash Commands Malfunction: System Commands Missing, Unexpected Behavior in Command Handling & Non-sensicle Actions

Bug Description

• System Slash Commands are missing, custom slash commands are showing up in multiples.
• When using system slash commands, several times instead of the normal processing, claude just takes over trying to guess what the command is?
• Claude is trying to use strange MCP tools like XcodeBuilder to debug, and started searching the MCP folder when I asked it to help solve the problem.
• Claudes actions are completely non-sensicle
• I asked claude to delete caches and instead it wanted to nuke the .claude file.
• There are none of the recent new feature Commands (agents, bash, status) in the command list anymore.
• When I use the /Commands - it tells me that I have 3 custom commands (which do not exist in my Customs), experimental, PR etc. and tells me to put the 00_meetclaude.md in my commands folder.

Specs:

• I am using the latest version, and at last login a few days ago things were working fine.

Environment Info

• Platform: darwin
• Terminal: WarpTerminal (Happening in iTerm also)
• Version: 1.0.44
• Feedback ID: aa5fe7ae-a26a-4af6-ab40-22c28ab7d8a1
