A combination of SQL and git seems to work best. They tend to complement each other really well.

git.exe can't tell you things like how many references a specific type has. It can get close with grep and friends, but it's not very precise. Preprocessing the codebase into various SQL tables using compiler tools can provide these insights in a much more stable way.

This reads like an AI writing to a point an author wants to make without there being evidence.

It is completely incoherent. Apparently we just need markdown and git, but also a knowledge graph and pgvector which accounts for most of the performance.

We don’t need semantic search, because we use… hybrid search (semantic search plus bm25)???

Really bad look for an AI consulting company this.

I’m confused: is it just markdown files in git? Or does the hybrid graph+semantic layer matter? If the latter is true, the title is just clickbait right

How does git replace a vector db search exactly? They are orthogonal. Are you gonna burn a million tokens every time you wanna find some relevant files?

I think just one useful thing is mentioned: put your md files in git and then have a hybrid fts/vector search across them actually does work better? Not a very surprising conclusion. Doesn't need that much text to explain, does it?

This should be common sense and immediately obvious to anybody who has spent more than a few hours with a coding agent.

This isn't even well-slopped slop.

I really don't get having a ton of MD files lying around. And the possibility of having to edit a thousand MD files when the metadata frontmatter changes.

A single SQLite database implements columns/metadata handling, and comes baked-in with FTS and BM25 ranking too.
