.claude/skills/paper-review/SKILL.md

paper-review is a skill for Claude Code from TakaGoto/rag-learning-academy. It costs 11 tokens per session (999 once invoked), scanned A, original, MIT.

A guided review for understanding research papers about retrieval-augmented generation, a method that looks up relevant information before producing an answer.

In plain words
What is it for?
Use it to review a paper, learn about retrieval and document chunking, compare approaches, and relate research findings to a RAG pipeline.
Why use it?
It turns difficult research into understandable parts and connects academic ideas to practical systems.

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

paper-review 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.

Paper Review: Understand RAG Research Papers

Break down RAG research papers into understandable pieces, connecting academic innovations to practical applications the learner can use in their pipeline.

Step 1: Identify the Paper

If the user provides a paper title or URL (e.g., /paper-review "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks"), use that. Otherwise, suggest papers from a curated list organized by topic:

Foundational Papers

  • "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks" (Lewis et al., 2020)
  • "Dense Passage Retrieval for Open-Domain Question Answering" (Karpukhin et al., 2020)
  • "REALM: Retrieval-Augmented Language Model Pre-Training" (Guu et al., 2020)

Chunking and Retrieval

  • "Sentence-BERT: Sentence Embeddings using Siamese BERT-Networks" (Reimers & Gurevych, 2019)
  • "ColBERT: Efficient and Effective Passage Search via Contextualized Late Interaction" (Khattab & Zaharia, 2020)

Advanced RAG

  • "Self-RAG: Learning to Retrieve, Generate, and Critique through Self-Reflection" (Asai et al., 2023)
  • "RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval" (Sarthi et al., 2024)

Evaluation

  • "RAGAS: Automated Evaluation of Retrieval Augmented Generation" (Es et al., 2023)

Ask the learner which paper interests them or recommend one based on their current module.

Step 2: Set Context

Before diving in, give the learner context:

  • What problem was this paper trying to solve?
  • When was it published and why did it matter at that time?
  • What should they pay attention to while reading?
  • How does it connect to what they have already learned?

Step 3: Section-by-Section Walkthrough

Break the paper down into digestible sections:

Abstract and Introduction

  • Summarize the core claim in one sentence
  • What gap in existing work does this address?
  • What is the proposed solution at a high level?

Background and Related Work

  • What prior work does this build on?
  • What are the key concepts the reader needs to understand?
  • Fill in any knowledge gaps the learner might have

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.

paper-review is a skill published in the GitHub repository TakaGoto/rag-learning-academy (19 stars, last pushed 5mo ago), licensed MIT. It adds 11 tokens to every session and 999 once invoked, about $0.0001 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 2026-08-30.
