rag-local-lancedb

rag-local-lancedb is a skill for Claude Code, Codex from pedroiff0/awesome-skills. It costs 35 tokens per session (230 once invoked), scanned A, original, MIT.

A guide for building local semantic search with LanceDB, a database for storing and finding vector representations of text, and HuggingFace or SentenceTransformers models. It is designed to run without cloud services.

In plain words
What is it for?
Creating offline search over Markdown files, codebases, or documentation; storing local text embeddings; and combining meaning-based search with ordinary full-text search.
Why use it?
It helps search local documents or code by meaning rather than exact words while keeping data and processing on the developer's machine.

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-local-lancedb 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 11d 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

Local RAG with LanceDB

This skill guides the construction and query execution of serverless, high-performance local vector databases using LanceDB and local embeddings.

When to Use

  • Building offline semantic search across local Markdown files, codebases, or documentation.
  • Storing vector embeddings with zero external cloud API costs.
  • Performing hybrid full-text + vector similarity queries.

Quick Setup & Python Usage

import lancedb

# Connect to local database directory
db = lancedb.connect("~/.local/share/agent_rag")
Changes

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.
