Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is echo "graph TD\n A --> B" | python3 ~/.claude/skills/aigc-detector/scripts/diagram_gen.py generate --output ./figures/fig1.png.

Good fit Use it to analyze or rewrite a thesis, reduce signs of AI-generated text, start a thesis-writing workflow, format documents, or create and insert charts.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

aigc-detector 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 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/diagram_gen.py, scripts/docx_io.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.

AIGC Detection, Rewriting & Thesis Writing Assistant

Bilingual academic paper assistant. Two modes: Detection & Rewrite (analyze existing papers for AI-generated content) and Thesis Writing (generate full thesis drafts from templates and code). Supports Chinese and English academic papers.


使用方式

分析论文 / Analyze paper:

  • "分析这篇论文的AIGC特征:/path/to/thesis.docx"
  • "Analyze this paper for AI-generated content: /path/to/thesis.docx"
  • "检测这篇论文的AI率"(然后粘贴文本)

改写论文 / Rewrite paper:

  • "帮我改写这篇论文降低AI率:/path/to/thesis.docx"
  • "Help me rewrite this paper to reduce AI detection rate: /path/to/thesis.docx"

撰写论文 / Write thesis:

  • "帮我写毕业论文,模板在About/目录"
  • "Help me write my graduation thesis, template is in About/"
  • "开始论文写作模式"(然后按提示操作)

Agent 适配说明

本 Skill 适配多种 AI Agent。以下是各 Agent 的工具映射:

功能 Claude Code 其他 Agent (Codex / Cursor / Windsurf / Gemini)
询问用户 AskUserQuestion 工具 输出选项编号,等待用户输入数字选择
保存文件 Write 工具 使用 Bash 写入文件
读取文档 Bash + python3 相同
生成图表 Bash + python3 diagram_gen.py 相同
插入图片 Bash + python3 docx_io.py insert_figure 相同
路径解析 .claude/skills/ → ~/.claude/skills/(fallback) ~/.claude/skills/(全局安装路径)

工作流程

严格按照以下步骤执行,不要跳过任何步骤。

模式选择(Mode Selection)

根据用户意图选择工作模式:

  1. 检测/改写模式(Detection & Rewrite Mode) — 用户要求分析或改写已有论文

    • 触发词:"分析""检测""改写""降低AI率""AIGC" + 文件路径或文本
    • 执行下方 检测/改写模式 步骤(Step 0-5)
  2. 论文写作模式(Thesis Writing Mode) — 用户要求撰写或生成论文

    • 触发词:"写论文""撰写""生成论文""毕业论文""thesis""write paper"
    • 执行下方 论文写作模式 步骤(Step W0-W5)
    • 详细指令见 references/thesis_writing_guide.md

如果用户意图不明确,使用 AskUserQuestion 工具询问:

  1. "检测/改写已有论文"
  2. "撰写新论文"

检测/改写模式(Detection & Rewrite Mode)

Step 0:语言检测

检测论文语言。如果用户提供了 .docx 文件,先执行 Step 1 读取文档获取文本后再检测语言。

  1. 分析输入文本的前500个字符
  2. 如果非标点字符中中文字符占比 > 60% → 语言 = "zh"
  3. 否则 → 语言 = "en"
  4. 后续所有步骤(分析、报告、改写)均使用检测到的语言

What ships with it

7 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.
