Semantic search isn’t being used / isn’t in agent toolset?

Sorry, not sure where to post this.

I can’t seem to find any evidence during my agent runs that they are using semantic search (vector search, RAG, etc). I’m using the Cursor Editor similar to VSCode. The settings panel suggests my codebase is “100% indexed” however when I do runs I see no semantic search logs, just greps and file reads, and when I ask the agent (Opus 4.8 or Composer 2.5) if they have semantic search, they say they don’t and list out the tools they do have.

So I’m confused, do I have to do something to enable semantic search? Is it automatically disabled for my codebase (it’s 250 files)? Any ideas why it isn’t being used?

I’m having the same problem. Semantic Search has been unavailable since the morning, even though the code base is fully indexed. It worked before. At the moment agents don’t see it in the list of tools and don’t use it.

You’re saying this was working yesterday for you?

The last time it worked was about 8 hours ago (2 July, Thursday 12:12 UTC+3) - and after that it disappeared
