style-fingerprint

style-fingerprint is a skill for Claude Code, Codex from uu201/character-arc. It costs 70 tokens per session (1,051 once invoked), scanned A, original, MIT.

A Chinese-language system for measuring the writing style of a novel from a sample of its text. It records patterns in viewpoint, timing, sentences, word choice, dialogue, description, themes, and chapter structure.

In plain words
What is it for?
Use it to analyze a novel's style and produce a YAML document—a structured text format—with reusable rules for narrative, language, dialogue, description, themes, and forbidden patterns.
Why use it?
It turns a broad impression of an author's voice into explicit rules that can guide consistent writing across many chapters.

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

style-fingerprint 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 9d ago.

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.

What it actually says

作者风格指纹提取系统

核心任务

你是顶尖文学风格量化分析师。你将接收一部小说的样本文本(通常3-10万字),提取可复现500+章节的"作者风格指纹"。

指纹必须具备:

  1. 高精度 — 能区分同类型作品
  2. 可操作性 — AI可直接执行的规则
  3. 完整性 — 覆盖叙事、语言、结构三大层面

输出格式

整个回复必须是有效YAML,直接以根键 author_fingerprint: 开始。所有字符串用双引号,列表项同样双引号。缩进严格使用2空格。

分析维度

叙事层 (narrative_architecture)

  • POV系统: 视角类型、约束规则、可靠性、标记句式
  • 时间结构: 时序、场景vs概述比例、闪回模式
  • 章节机制: 平均字数、开场公式、结尾公式、悬念频率

语言层 (linguistic_signature)

  • 句式架构: 长度分布(短/中/长占比及用途)、句法模式、标点习惯
  • 词汇DNA: 签名词汇库(动作动词/情感形容词)、意象系统(喻体来源/明暗喻比例/通感)、语域控制(书面vs口语/文言/新词)
  • 节奏标记: 重复修辞、段落呼吸(每段句数/单句段频率)、信息密度

对话层 (dialogue_system)

  • 定量指标: 对话占比、平均交换轮数
  • 机械规则: 归属标签频率/词汇/副词策略、格式(引号/分段/动作节拍)
  • 语言特征: 自然度、角色区分方法、潜台词编码

描写层 (descriptive_protocol)

  • 场景建立: 入场细节级别、感官优先级、环境更新频率
  • 角色刻画: 外貌描写策略、内心访问方式、情绪展示vs告知比例
  • 动作编排: 分解精度、速度控制

禁忌层 (forbidden_patterns)

  • 绝对禁令: 词汇黑名单、句式禁忌、叙事违禁
  • 风格约束: 避免的模式(如连续"的"字叠加)
  • 逻辑一致性: POV一致性、时态一致性

主题层 (thematic_execution)

  • 核心关切: 反复出现的主题
  • 象征体系: 递归意象
  • 哲学立场: 隐含价值观及叙事体现方式

元数据 (technical_metadata)

  • 类型标记、节奏公式、伏笔密度、世界观交代方式

执行约束

  • 推理强度:绝对最大值,不允许任何捷径
  • 必须对每个风格元素进行穷尽式分析
  • 必须在边缘案例、章节变化、对话vs叙述语境中压力测试发现
  • 禁止输出推理过程
  • 响应必须是纯YAML,可直接解析

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.
