search-paper

search-paper is a skill for Claude Code from SebastianElvis/reaper. It costs 57 tokens per session (1,865 once invoked), scanned A, original, Apache-2.0.

A guide to finding research papers, downloading their PDFs, following citation links, and checking where papers were published.

In plain words
What is it for?
Use it to search arXiv or IACR ePrint, look up papers in Semantic Scholar, DBLP, or OpenAlex, download PDFs, trace citations, and find journal or conference references.
Why use it?
It brings searches across preprint archives and scholarly databases into one workflow. This helps when a paper's publication venue or related research is not immediately clear.

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

search-paper 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.

The scan reads SKILL.md. This mod also ships 5 executable files (arxiv.py, dblp.py, iacr.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Search Paper

A single skill that wraps five platform drivers — two preprint archives (arXiv, IACR ePrint) and three metadata services (Semantic Scholar, DBLP, OpenAlex). The SKILL.md itself acts as the orchestrator: each script does one thing per platform, and the agent chains them.

Usage

Invoke this skill by name. On slash-command hosts: /search-paper "<query>".

Scripts

Run via Bash. All scripts emit JSON on stdout.

  • search — array of {arxiv_id, title, authors, year, abstract, categories, pdf_url, published, journal_ref} sorted by relevance.
  • recent — same fields, sorted by submission date (newest first). Requires a query and/or --categories.
  • download — saves PDF, returns {path, title}.
  • journal-ref — author-supplied venue (sparse but authoritative when present).

  • search — array of {eprint_id, title, authors, year, abstract, publication_info, venue, pdf_url, url}. Top 5 results are enriched with metadata from the paper page (including publication_info).
  • recent — most-recently-posted ePrint papers.
  • download / url — PDF download and URL resolution.
  • pubinfo — scrapes the "Publication info" line from the paper page (e.g. "A major revision of CRYPTO 2023") and best-effort parses out the venue acronym + year.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
