Chroma

This gives Claude Code integration with Chroma, the open-source vector database built for LLM applications. If you're building RAG systems or need semantic search over documents, this is the local, self-hosted option instead of reaching for a managed service. Chroma has real traction with 24,000+ GitHub stars and Apache 2.0 licensing, so you're not betting on something experimental. The skill is part of davila7's template collection, originally from ovachiever/droid-tings. It's straightforward: you need embeddings storage with metadata filtering, and you want to keep everything running locally or in your own infrastructure. Works well for prototyping in notebooks before you commit to production infrastructure.
