What's Wrong?

When interacting with claude code on a rust project I saw

❯  LSP Plugin Recommendation                                                                                                                                               

     LSP provides code intelligence like go-to-definition and error checking                                                                                               

     Plugin: rust-analyzer-lsp

     Triggered by: .rs files                                                                                                                                               

     Would you like to install this LSP plugin?                                                                                                                            
     ❯ 1. Yes, install rust-analyzer-lsp                                                                                                                                   
       2. No, not now                                                                                                                                                      
       3. Never for rust-analyzer-lsp                                                                                                                                      
       4. Disable all LSP recommendations

A few problems here

• the first time I saw it I chose "No" and then asked claude code what this plugin was - I said something like "I just got prompted to install a plugin something to do with rust LSP - where did that come from?"; claude knew nothing about it, and denied having put up the suggestio
• the second time I saw it, I pasted the above into claude code and it said that this was in fact a plugin recommendation from claude code
• I then asked for more details about this plugin with particular reference to whether the plugin itself communicated off-host and claude did not know the answers

A couple of things would be good to address

1. Transparency: The LSP recommendation prompt should clearly state it originates from Claude Code itself, not a third party.
2. Accountability: When Claude Code recommends a plugin, Claude should be able to definitively answer whether it runs locally or sends data off-machine — "I'm not sure" is not an acceptable answer for a privacy-relevant question about a feature Claude Code itself surfaced.

What Should Happen?

as above
