Kilo Code has re-introduced codebase indexing as a generally available, opt-in feature. It adds a semantic_search tool to the Kilo agent, allowing it to find code by concept rather than exact string matching. The feature uses Tree-sitter for parsing code into semantic chunks, stores embeddings in a vector store (e.g., LanceDB), and supports providers like Kilo's hosted service, Mistral BYOK, or Ollama. Indexing is incremental and hash-cached, and can be enabled per-project or globally via settings UI, CLI, or config file. The implementation was largely contributed by community member shssoichiro and graduated from experimental status after weeks of testing and feedback.
