What it does
Cnki Crawler is an agent skill from Drchronx/ai-agent-research-starter-kit. Crawl CNKI journal paper metadata with the local Python crawler and save to PostgreSQL. Supports multi-sort retrieval (DFR/CF/PT/ZH) and mandatory query validation. Use when the user asks to collect CNKI papers, run the CNKI crawler, or query by CNKI field patterns.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts (for example `reference/专业检索语法.md`, `scripts/__init__.py` and `scripts/cnki_db.py`).
It sits in Data & Analytics, covering Web scraping. It works with PostgreSQL and Python. The repository describes itself as: AI Agent 科研全流程教学包，能教学生从零部署 Codex、Claude Code、OpenClaw、Hermes 等 Agent，学会使用 Skills、飞书、AMiner、AI4Scholar、Zotero、Obsidian…
When your agent uses it
- The user asks to collect CNKI papers
- Run the CNKI crawler
- Query by CNKI field patterns
Example prompts

Requirements
- Python 3

What it can do on your machine
Read from SKILL.md and the folder at commit aab1133. 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 8 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
Cnki Crawler loads about 1.4k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 177 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:26
cp .env.example .env - NoteMentions a .env fileSKILL.md:27
# 编辑 .env 设置 CNKI_DB_DSN, CNKI_PROXY_HTTP, CNKI_PROXY_HTTPS - NoteMentions a .env fileSKILL.md:177

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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 177 words (~1,429 tokens).
