What it does

This skill analyzes a research source in depth and writes an Obsidian note with evidence and extracted images. It first identifies what it was given: an arXiv ID or link, a public PDF URL, a local PDF, a research project or company page, a blog post, a plain web page or only a title. It will not assume arXiv from a number, and will not invent arXiv metadata for a blog or an ordinary PDF. The skill text is in Chinese.

A resolver script, resolve_source.py, classifies the input into source.json. The agent checks the vault for duplicates by document ID, arXiv ID, normalized title and source URL, keeps manual content in existing notes, and bases the analysis on the PDF text or page body, separating the author's claims, cited evidence and its own inference. generate_note.py creates a note template only when none exists, with a research structure for papers or a source structure for blogs and pages, and update_graph.py records the note in the vault's graph once placeholders are filled. Images for papers come from a sibling extract-paper-images skill.

It needs OBSIDIAN_VAULT_PATH pointing at the vault, with a Papers folder under 20_Research, and defaults the note language to zh when none is configured. If full text is unavailable it analyzes only what is visible and states the gap.

When your agent uses it

  • Summarizing and evaluating an arXiv paper by ID or link
  • Analyzing a public PDF URL or a local PDF
  • Capturing a research project page or technical blog post into the vault
  • Updating an existing Obsidian note without losing manual content

Example prompts

  • “Analyze the paper at this arXiv link and write a note in my Obsidian vault.”
  • “Read the company research page at this URL together with its linked PDF, then create a note.”
  • “Summarize ./papers/attention-survey.pdf into my vault and mention anything you could not verify.”

Requirements

  • OBSIDIAN_VAULT_PATH pointing to an Obsidian vault
  • Python to run the bundled scripts

Workflow steps

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

  1. 将当前 SKILL.md 的父目录视为 。
  2. 从 OBSIDIAN_VAULT_PATH 解析 ;缺失时要求用户提供 Vault 路径。
  3. 验证 /20_Research/Papers,读取研究配置中的 language;缺失时使用 zh。
  4. 在系统临时目录创建本次 ,不在 skill 目录或 Vault 中保存临时下载。

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

    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

Paper and Web Source Analyzer loads about 715 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~715

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 211 words (~715 tokens).

“先确定来源类型,再选择论文或网页分析结构。不得因输入含数字就假定是 arXiv,也不得给博客、公司报告或普通 PDF 伪造 arXiv 元数据。”
