papers-research

papers-research is a skill for Claude Code from xwmxcz/papers-skill. It costs 45 tokens per session (1,218 once invoked), scanned A, original, MIT.

A research helper for finding academic papers, reading their PDFs, and collecting paper details, references, and citations. It uses sources such as Semantic Scholar and arXiv, a site for sharing early research papers.

In plain words
What is it for?
Use it to search by topic, inspect paper metadata and references, find papers that cite a given paper, and download and read arXiv PDFs.
Why use it?
It removes the need to search several research sites and handle paper PDFs manually during a literature review.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

papers-research 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/papers.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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Papers Research

Skill-mode port of papers-mcp. Orchestrates a bundled Python CLI (scripts/papers.py) via Bash to search papers, fetch metadata/citations, and download + read PDFs.

One-time setup

Verify dependencies (only once per machine):

python -c "import httpx, arxiv, fitz" 2>&1 || pip install httpx arxiv PyMuPDF

If python isn't on PATH, use py (Windows) or the full interpreter path.

Invocation

The script lives at ${CLAUDE_PLUGIN_ROOT}/skills/papers-research/scripts/papers.py — this variable is auto-substituted by Claude Code's plugin loader. Always quote the path (it may contain spaces).

python "${CLAUDE_PLUGIN_ROOT}/skills/papers-research/scripts/papers.py" <subcommand> [args]

Subcommands

Subcommand What it does Example
search <query> [--limit N] Semantic Scholar search (cap 20) search "diffusion models" --limit 5
detail <paper_id> Full metadata, TL;DR, top 10 references detail 10.48550/arXiv.2310.06825
citations <paper_id> [--limit N] Papers that cite this one (cap 20) citations <id> --limit 15
arxiv <query> [--max-results N] arXiv preprint search (cap 10) arxiv "RLHF" --max-results 5
download <arxiv_id> [--save-dir D] Save PDF locally download 2310.06825 --save-dir ./pdfs
read <pdf_path> [--max-pages N] Extract PDF text via PyMuPDF read ./pdfs/foo.pdf --max-pages 20

Paper ID conventions

detail and citations auto-detect ID type:

  • DOI (10.xxxx/...) → used as-is
  • arXiv (ARXIV:2310.06825, or bare numeric ≥10 digits → auto-prefixed)
  • Semantic Scholar paperId (long hex string) → used as-is

download requires a plain arXiv ID like 2310.06825 (no prefix).

Standard workflows

A — Literature scan

  1. Run search <topic>.
  2. Present results as a ranked table: # | Title | Year | Citations | ID.
  3. Ask which paper(s) to dig into.

B — Deep-read one paper

  1. detail <id> → confirm match, show abstract + TL;DR.
  2. If arXiv ID present: download <arxiv_id> --save-dir ./pdfs.
  3. read <pdf_path> (default 10 pages = abstract + intro + conclusion; raise to 30+ for full read but warn about context usage).
  4. Summarize: problem · method · key result · limitations.

Files

What ships with it

1 file 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.
