I don’t think that “Claude Code” is relevant to this semantic grep tool.

bear in mind that Claude Code by default uses grep - if you watch you'll see if it's looking for something it doesn't know the name of, it flails around with different patterns. Try this tool, tell CC to take a look using ck --help and take it for a spin.

CC in my case likes it so much, it started using it to debug the repo rather than grep and suggesting its own additions

Note that it’s grep AND semantic - so Claude can start with a grep strategy and if it finds nothing can switch to semantic, and since it’s local and fast, it keeps in sync easily enough

How do you tell CC to use it? Just as an entry in Claude.md?

To start with just tell it- but yes Claude.md works too.

“We have a new grep semantic hybrid tool installed called ck - check it out using ck --help and take it for a spin”

Why would "not using embeddings" be a selling point? Some of the most effective IR systems use embeddings (bi-encoders, cross-encoders)
