vector-database
Work with vector databases for RAG, embeddings, and semantic search using ChromaDB or similar. Use when building knowledge bases for PSI Engine or AI-powered search.
npx skills add majiayu000/claude-skill-registry --skill vector-database-lovedragonball-power-ranger-toolkit --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 🧮 Vector Database Skill ## ChromaDB Setup ### Installation ```bash pip install chromadb ``` ### Initialize ```python import chromadb # Persistent storage client = chromadb.PersistentClient(path="./chroma_db") # In-memory (testing) client = chromadb.Client() # Get or create collection collection = client.get_or_create_collection( name="knowledge_base", metadata={"hnsw:space": "cosine"} ) ``` --- ## CRUD Operations ### Add Documents ```python collection.add( documents=["How to fix null pointer exception in Python"], metadatas=[{ "source": "agent_1", "category": "debugging", "language": "python", "date": "2026-01-14" }], ids=["doc_001"] ) ``` ### Query (Semantic Search) ```python results = collection.query( query_texts=["null reference error"], n_results=5, where={"category": "debugging"}, include=["documents", "metadatas", "distances"] ) # Results for i, doc in enumerate(results['documents'][0]): print(f"Score: {results['distances'][0][i]}") print(f"Doc: {doc}") ``` ### Update ```python collection.update( ids=["doc_001"], documents=["Updated solution for null pointer"], metadatas=[{"updated": True}] ) ``` ### Delete ```python collection.delete(ids=["doc_001"]) # or collection.dele

What does the vector-database skill do?
Work with vector databases for RAG, embeddings, and semantic search using ChromaDB or similar. Use when building knowledge bases for PSI Engine or AI-powered search.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill vector-database-lovedragonball-power-ranger-toolkit --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
