Good bot, this comment was able to resolve it for me. https://github.com/anthropics/claude-code/issues/2910#issuecomment-3049944606

I install RG and now all functionality is working as expected. It would be really great to document this dependency in the installation guide. It's not at all obvious that it's required and just fails these features silently.

Would be even better to check for system dependencies via the doctor command.

Thanks for flagging this issue - we actually bundle rg, but it looks like that's not working properly on Amazon Linux 2. We'll look into this.

Can you share what version of glibc you have, as well as what the results of claude !rg --version are?

This is the version I had on my system path before it was working.

rg --version                                                                                                                    ✘ INT
ripgrep 12.1.1
-SIMD -AVX (compiled)
+SIMD +AVX (runtime)

And this is the version I installed that got it working

rg --version
ripgrep 14.1.1

features:+pcre2
simd(compile):+SSE2,-SSSE3,-AVX2
simd(runtime):+SSE2,+SSSE3,+AVX2

PCRE2 10.43 is available (JIT is available)

We shipped some improvements in 1.0.84 that should help diagnose / mitigate this:

1. claude /doctor now shows the status of Search related functionality (which includes custom slash command discovery)
2. Claude Code now prefers built-in rg over system-installed rg (see https://docs.anthropic.com/en/docs/claude-code/troubleshooting#search-and-discovery-issues)
3. You can also run with --debug to see if there are rg related errors

We also fixed some aarch-related Linux issues. Note that if you're using the native executable (as opposed to npm), you will need to explicitly install rg and set USE_BUILTIN_RIPGREP=0.

Was able to verify this is working on an older desktop I didn't upgrade rg on. Thanks so much! The new debug feature is going to be awesome for troubleshooting system issues like this!
