[Bug] Most build-in Slash Commands Not Working in VS Code Extension 2.0.x

[sipaan]

Bug Description
After updating to Claude Code extension 2.0.x (now on 2.0.5 ) in VS Code, most built-in slash commands no longer work.
For example, when I type /help or /rewind in the Claude input box, I only see “no matching commands”. No dropdown or command execution happens. in the vs code claude terminal i do get those commands there they work fine only in extension they dont appear.

Environment:
VS Code: latest stable release (e.g. 1.104.2)
Claude Code Extension: 2.0.5
OS: Windows 11

Steps to Reproduce:
Install Claude Code extension v2.0.5.
Open the Claude chat panel in VS Code.
Type /help or /rewind.
Result: “no matching commands” instead of showing the built-in command list.

Expected Behavior:
Typing /help should show the available built-in commands. Typing /rewind should rewind the conversation.

Troubleshooting Tried:
Verified VS Code is on the newest version.
Uninstalled/reinstalled VS Code with cleanup
Uninstalled/reinstalled Claude Code extension.

Current Result:
Slash commands like /help and /rewind don’t work, always showing “no matching commands”.

Request:
Could you confirm if this is a known bug in 2.0.5? And is there a workaround or upcoming fix so that built-in slash commands become available again?

same issue with me, there and rewind is a really important one too

• This a serious issue. I just want to know if this is being worked on.
• The bot tags it as properly a bug yet it threatens to close it as a duplicate? That's a very mixed message.
• How are we supposed to know, if this is the right bug to watch for progress on fixing it.
• Still an issue in vscode extension version 2.0.9

Same problem for me, I don't see rewind or agents commands.

Same for me with m1 mac

In my vs code, it does not work in claude code extension but it works if I run slash commands in terminal inside vs code

[davefollett]

In addition to slash commands missing, I can no longer run ANY custom commands that I have created. Falling back to running claude in a terminal inside vscode to have a working environment.

MacOS 15.7.1

Same in Ubuntu.

Same issue here.
Win10, Cursor/VSC, multiple computers, version 2.0.13.

Commands show up in terminal version.

The CLI doesn't show slash commands in its help - they're runtime features. Let me check the critical debug output again from your log:
[DEBUG] Slash commands included in SlashCommand tool:
This line appears but is EMPTY! The backend is trying to send slash commands to the SlashCommand tool, but the list is empty.

This is definitely a bug
Given that:
It happens on multiple machines
The backend loads successfully but provides zero slash commands
The CLI (terminal) version works fine
