paper-agent: Skill for Claude Code

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

paper-screener is a skill for Claude Code from Guo-Chenxu/paper-agent. It costs 45 tokens per session (2,915 once invoked), scanned A, original, Apache-2.0.

A research-paper screening tool that filters papers in two stages: first by title and abstract, then by reading the full PDF. It combines scores and creates structured summaries and a report.

In plain words
What is it for?
Use it after paper crawling to rank papers, resolve disagreements between reviewers, summarize selected studies, and prepare literature-review material.
Why use it?
It helps narrow a large paper collection to relevant, higher-quality studies while keeping track of how decisions were made.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: reads .claude/ paths; mentions subagents.

This is Guo-Chenxu/paper-agent's own configuration. It tells Claude Code how to work on paper-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything paper-agent configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is --abstracts-dir ./papers/abstracts \.

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-screener 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/load_papers_for_screening.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.

Paper Screener

Skill Goal

Automated two-round paper screening and structured summarization:

  1. Round 1: Title+abstract pre-screening with 3 parallel agents for fast coarse filtering
  2. Round 2: Full-text deep screening with 3 parallel agents reading complete PDFs
  3. Score aggregation with arbitration when agent disagreement exceeds threshold
  4. Structured paper summaries for high-scoring papers, generated from full-text reading
  5. Comprehensive screening report with statistics, rankings, and traceability

When To Use

  • After paper crawling produces abstracts and metadata
  • Need to filter and rank candidate papers by quality and relevance
  • Want structured, full-text-based summaries of selected papers
  • Preparing input for literature review or research idea generation

Prerequisites

Required inputs from a prior crawl run:

  • ./papers/abstracts/*.txt — abstract text files
  • ./papers/metadata/papers_*.json — paper metadata records
  • ./papers/pdfs/*.pdf — full-text PDFs (required for Round 2; download if missing)

Required Python packages:

python -m pip install requests

Scripts

  • Load papers for screening: ./scripts/load_papers_for_screening.py

Workflow

Step 1: Load and Prepare Papers

python .claude/skills/paper-screener/scripts/load_papers_for_screening.py \
  --abstracts-dir ./papers/abstracts \
  --metadata-dir ./papers/metadata \
  --output screening_input.json

This produces a JSON file with paper titles, abstracts, venues, years, and authors for agent scoring.

Step 2: Round 1 — Title+Abstract Pre-Screening

Purpose: Fast coarse filtering to reduce the candidate set. Scores from this round are NOT used as final quality judgments.

Spawn 3 parallel subagents, each scoring every paper independently. Each agent receives only the title and abstract.

Scoring Criteria (1–10 total):

Dimension Points Description
Relevance 5 Fit with the target research domain
Potential Innovation 3 Novelty indicated in the abstract
Publication Quality 2 Venue tier, citation count

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.

paper-screener is a skill published in the GitHub repository Guo-Chenxu/paper-agent (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 45 tokens to every session and 2,915 once invoked, about $0.0002 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 2026-08-31.
