wshobson-rag-implementation

wshobson-rag-implementation is a skill for Claude Code, Codex from ItamarZand88/awesome-agent-conventions. It costs 0 tokens per session (1,122 once invoked), scanned A, original, MIT.

A guide to building retrieval-augmented generation (RAG) systems, where an AI looks up relevant documents before answering. It covers embeddings, which turn text into searchable numerical representations, and vector databases, which store them.

In plain words
What is it for?
Use it to build document question-answering tools, semantic search, documentation assistants, research tools, and chatbots connected to external information.
Why use it?
It helps AI applications answer from company documents or other knowledge sources instead of relying only on the model's memory. This can reduce unsupported answers.

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

wshobson-rag-implementation scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

name: rag-implementation description: Build Retrieval-Augmented Generation (RAG) systems for LLM applications with vector databases and semantic search. Use when implementing knowledge-grounded AI, building document Q&A systems, or integrating LLMs with external knowledge bases.

RAG Implementation

Master Retrieval-Augmented Generation (RAG) to build LLM applications that provide accurate, grounded responses using external knowledge sources.

When to Use This Skill

  • Building Q&A systems over proprietary documents
  • Creating chatbots with current, factual information
  • Implementing semantic search with natural language queries
  • Reducing hallucinations with grounded responses
  • Enabling LLMs to access domain-specific knowledge
  • Building documentation assistants
  • Creating research tools with source citation

Core Components

1. Vector Databases

Purpose: Store and retrieve document embeddings efficiently

Options:

  • Pinecone: Managed, scalable, serverless
  • Weaviate: Open-source, hybrid search, GraphQL
  • Milvus: High performance, on-premise
  • Chroma: Lightweight, easy to use, local development
  • Qdrant: Fast, filtered search, Rust-based
  • pgvector: PostgreSQL extension, SQL integration

2. Embeddings

Purpose: Convert text to numerical vectors for similarity search

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.
