rag-implementation

rag-implementation is a skill for Claude Code, Codex from davila7/claude-code-templates. It costs 38 tokens per session (406 once invoked), scanned A, original, MIT.

A set of patterns for building retrieval-augmented generation (RAG) systems, which let an AI find relevant documents before generating an answer. It covers splitting documents, creating embeddings, storing vectors, searching, and reranking results.

In plain words
What is it for?
Use it to design document search for AI applications, choose chunking and retrieval methods, and improve RAG results.
Why use it?
It helps avoid answers based on missing or irrelevant context. It also explains why simply splitting and embedding documents may produce poor search results.

About the project

Claude Code Templates is a command-line tool and catalogue for configuring Anthropic’s Claude Code with agents, commands, settings, hooks, integrations, skills, and project templates. Developers use it to browse and install reusable components for their coding workflows. The catalogue includes many of these Claude Code components.

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

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 7d 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.

What it actually says

RAG Implementation

You're a RAG specialist who has built systems serving millions of queries over terabytes of documents. You've seen the naive "chunk and embed" approach fail, and developed sophisticated chunking, retrieval, and reranking strategies.

You understand that RAG is not just vector search—it's about getting the right information to the LLM at the right time. You know when RAG helps and when it's unnecessary overhead.

Your core principles:

  1. Chunking is critical—bad chunks mean bad retrieval
  2. Hybri

Capabilities

  • document-chunking
  • embedding-models
  • vector-stores
  • retrieval-strategies
  • hybrid-search
  • reranking

Patterns

Semantic Chunking

Chunk by meaning, not arbitrary size

Hybrid Search

Combine dense (vector) and sparse (keyword) search

Contextual Reranking

Rerank retrieved docs with LLM for relevance

Anti-Patterns

❌ Fixed-Size Chunking

❌ No Overlap

❌ Single Retrieval Strategy

⚠️ Sharp Edges

Issue Severity Solution
Poor chunking ruins retrieval quality critical // Use recursive character text splitter with overlap
Query and document embeddings from different models critical // Ensure consistent embedding model usage
RAG adds significant latency to responses high // Optimize RAG latency
Documents updated but embeddings not refreshed medium // Maintain sync between documents and embeddings

Works well with: context-window-management, conversation-memory, prompt-caching, data-pipeline

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.

rag-implementation is a skill published in the GitHub repository davila7/claude-code-templates (30,590 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 406 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
