using-weaviate

using-weaviate is a skill for Claude Code from FortiumPartners/ensemble. It costs 39 tokens per session (3,193 once invoked), scanned A, original, MIT.

A reference guide for Weaviate, an open-source database that stores data for meaning-based searches and structured filters.

In plain words
What is it for?
It covers storing embeddings, similarity search, combined keyword and meaning-based search, retrieval-augmented generation, and multi-tenant applications.
Why use it?
It helps developers build search and AI applications without having to look up Weaviate's operations and patterns.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

using-weaviate scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Weaviate Vector Database Skill

Version: 1.0.0 | Target: <500 lines | Purpose: Fast reference for Weaviate operations


Overview

What is Weaviate: Open-source vector database for AI-native applications combining vector search with structured filtering and keyword search.

When to Use This Skill:

  • Storing and querying vector embeddings
  • Implementing semantic/similarity search
  • Building RAG (Retrieval-Augmented Generation) pipelines
  • Hybrid search (vector + keyword)
  • Multi-tenant vector applications

Auto-Detection Triggers:

  • weaviate-client in requirements.txt or pyproject.toml
  • weaviate-client or weaviate-ts-client in package.json
  • WEAVIATE_URL, WEAVIATE_API_KEY, or WCD_URL environment variables
  • docker-compose.yml with semitechnologies/weaviate image

Progressive Disclosure:

  • This file (SKILL.md): Quick reference for immediate use
  • REFERENCE.md: Comprehensive patterns, modules, and advanced configuration

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
