## FAQ

### How does Codemesh improve AI agent performance?

It provides a persistent knowledge graph that allows agents to map repositories and read exact symbols instead of grepping through files and reading irrelevant code.

### Does Codemesh require a vector database?

No, it uses a single SQLite database located in a .codemesh/ directory and does not generate embeddings.
