rag-implementation

rag-implementation is a skill for Claude Code, Codex from Zhow01/SkillAttack. It costs 49 tokens per session (2,840 once invoked), scanned B, original, no licence file.

A guide for building retrieval-augmented generation systems, which let an AI answer using information retrieved from documents or other knowledge sources. It covers vector databases and semantic search, which find relevant content by meaning.

In plain words
What is it for?
Use it to build document question-answering systems, connect language models to knowledge bases, and retrieve supporting context for responses.
Why use it?
It helps reduce answers that rely only on the AI model's built-in knowledge or miss relevant external information.

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 B, and why

rag-implementation scanned grade B with 2 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 1mo 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 Zhow01/SkillAttack (57 stars, last pushed 5mo ago), with no licence file. It adds 49 tokens to every session and 2,840 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
