At a glance

Searches arXiv for recent papers matching your research interests, scores them and writes a daily recommendation note into an Obsidian vault.

  • Works in 3 steps: 获取今日日期 → 读取研究配置 → 扫描现有笔记构建索引
  • Starting a research day with fresh arXiv paper recommendations
  • SKILL.md covers Language Detection, 工作流程概述, 步骤1:收集上下文(静默) and 步骤2:搜索论文, plus 9 more sections
  • Runs Python scripts from its folder; calls python

What it does

This skill is written mostly in Chinese and generates a daily paper brief to open a research day. It reads a research_interests.yaml config in the 99_System/Config folder of your Obsidian vault, scans existing notes under 20_Research/Papers to build a keyword-to-note index for automatic links, then runs scripts/search_arxiv.py to query the arXiv API for recent papers in the relevant categories.

The script fetches up to 200 recent papers, parses the XML, filters them by your interests and ranks them with a combined score that weights relevance, recency, popularity and quality, keeping the top 10 in arxiv_filtered.json. The report language, Chinese by default or English, comes from a language field in the config. The description also mentions Semantic Scholar recommendations, and further scripts handle keyword linking and common-word filtering.

When your agent uses it

  • Starting a research day with fresh arXiv paper recommendations
  • Generating a paper brief for a specified date
  • Filling an Obsidian vault with scored, auto-linked paper notes

Example prompts

  • “Start my day and create today's paper brief.”
  • “Generate the paper recommendations for last Friday and write them in English.”
  • “Update my research brief with the latest papers on diffusion models and link them to my existing notes.”

Requirements

  • An Obsidian vault with OBSIDIAN_VAULT_PATH set
  • A research_interests.yaml config file in the vault
  • Python for the search scripts
  • Network access to the arXiv API

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 获取今日日期
  2. 读取研究配置
  3. 扫描现有笔记构建索引

What it can do on your machine

Read from SKILL.md and the folder at commit ef3a594. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 4 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Daily arXiv Paper Brief loads about 4.3k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 758 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 758 words (~4,317 tokens).
