reference-download

reference-download is a skill for Claude Code, Codex from sillyDaibo/reasflow-dev. It costs 40 tokens per session (1,297 once invoked), scanned A, original, MIT.

A workflow for downloading and processing academic papers from arXiv, a public repository for research preprints. It focuses on extracting mathematical material such as algorithms, lemmas, and theorems from LaTeX source files.

In plain words
What is it for?
Use it to download arXiv papers, unpack their source, and locate or analyze algorithms, lemmas, theorems, and other mathematical content.
Why use it?
It makes research references easier to obtain and inspect when a proof or mathematics project needs details from a paper’s source rather than only its rendered pages.

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

reference-download 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 5d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/download-arxiv-reference.py, scripts/download-arxiv.sh, scripts/search-math-content.sh), 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.

文献下载与处理

概述

本 skill 提供下载、解压和分析学术文献(尤其是 arXiv LaTeX 格式论文)的完整工作流,支持数学证明项目高效获取参考资料。

快速开始

下载 arXiv 论文

python "$REASFLOW_PRIVATE_SKILLS_ROOT/prover/reference-download/scripts/download-arxiv-reference.py" \
  --arxiv-id <arXiv_ID> \
  --output-dir prover/references/<ref_name> \
  --workspace <workspace>

# 示例:
# --arxiv-id 2101.11203 --output-dir prover/references/ref_fedavg

下载完成后,脚本会列出所有 .tex 文件。

搜索数学内容

下载后,使用 rg 高效定位数学内容:

# 定位所有引理和定理位置(推荐优先执行)
rg "\begin\{lemma\}|\begin\{theorem\}|\begin\{assumption\}" prover/references/<ref_name>/ -n

# 定位算法
rg "\begin\{algorithm\}|\begin\{algorithmic\}" prover/references/<ref_name>/ -n

# 定位证明
rg "\begin\{proof\}" prover/references/<ref_name>/ -n

工作流程

第1步:下载与解压

  • 使用下载脚本自动完成下载和解压
  • 文件自动组织到 <workspace>/prover/references/
  • 支持 .tar.gz.zip 格式

第2步:搜索与定位数学内容

必须使用 rg 先锁定,不要直接读取长文件

# 全面概览(推荐首先执行)
rg "\begin\{lemma\}|\begin\{theorem\}|\begin\{assumption\}|\begin\{algorithm\}" \
  prover/references/<ref_name>/ -n

# 搜索收敛性相关内容
rg "convergence\|converge\|descent" prover/references/<ref_name>/ -l

Files

What ships with it

3 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.

reference-download is a skill published in the GitHub repository sillyDaibo/reasflow-dev (2 stars, last pushed 9d ago), licensed MIT. It adds 40 tokens to every session and 1,297 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.
