@khromov What is the output of claude --version? Do you have more specific steps to reproduce, like which slash command?

@trav The version is 1.0.127. It's very simple to reproduce:

1. Run claude mcp add --transport http --scope project svelte-llm https://svelte-llm.stanislav.garden/mcp/mcp
2. Run claude
3. Type /svelte-llm and tab to fill in any of the suggested resources
4. Press enter and you get Unknown slash command: svelte-llm:Svelte almost like it can't handle spaces correctly, the name of the command gets cut off

This has worked before and broke maybe 1-2 months ago.

Had the same problem - custom commands AND agents not showing up in /help even though search was working.

Found the culprit was my ripgrep config. I had --color=always in my ~/.ripgreprc which was embedding ANSI color codes in file paths during Claude Code's
discovery process. It was trying to read files like [0m[1m[32m/path/to/command.md[0m instead of the actual path.

Fixed it by changing --color=always to --color=auto in my ripgrep config. Still get colors in terminal but Claude Code gets clean paths for file
discovery.

Worth checking if you have custom ripgrep settings - might be the same issue.

@mg-dev25 Do the repro instructions I posted work correctly for you?

The only thing I'm using is Oh My Zsh, but even starting a new terminal from sh and launching claude does not solve the issue.

@khromov Do you have ripgrep install on your system, Claude code are using it if he found it and this cause a lot of issue.
Did the issue happen only in VSCode ? What if you run Claude code in a normal terminal ?

Can you run claude --debug to see what if he found a particular issues?

I do not have ripgrep/rg installed:

➜  tmp rg
zsh: command not found: rg
➜  tmp ripgrep
zsh: command not found: ripgrep

The error happens on both mac terminal and vscode terminal.

Running with --debug flag and reading /Users/k/Library/Logs/claude-cli-nodejs/-Users-k/debug-logs/debug.txt does show some ripgrep stuff, but it seems that it ultimately fails and doesn't use it? Also I cant' see the actual original error (which seemed to be a JSON parsing issue: SyntaxError: Unexpected token 'H', \"Here's a d\"... is not valid JSON). So I am not convinced this has to do with ripgrep but rather that Claude seems to mess up the JSON encoding.

Claude code as built in ripgrep in its code. For me, I change the ENV to use the one on my system and use my ripgrep config not the build in config inside claude code. You can test installing it in your system and create a config file at the home dir to force color in auto. If rg fail he will not find your commands and agents
