Sentence Transformers

This gives Claude Code access to the Sentence Transformers library, which generates text embeddings locally without API calls. You'd reach for this when building RAG systems, semantic search, or anything needing similarity comparisons across text. The framework has 15,700+ GitHub stars and offers 5,000+ pretrained models covering 100+ languages, making it a solid alternative to paid embedding APIs. It's based on PyTorch and Transformers, so if you're already in that ecosystem, integration is straightforward. The skill has passed security audits from Gen Agent Trust Hub, Socket, and Snyk, with 374 installs so far.
