What is novel-knowledge?

A command-line knowledge graph for a novel’s entities, such as characters, places, items, groups, and concepts. It searches, creates, relates, tags, and indexes these story records.

Use it to search setting information, query an entity’s relationships, find records by tag, create entity templates, and rebuild the index after edits.

It gives other writing tools a structured way to find story facts and relationships instead of relying only on scattered notes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add TulanCN/vibe-noveling --skill novel-knowledge

Clone the repo

git clone --depth 1 https://github.com/TulanCN/vibe-noveling

Made for: Claude Code.

Or install vibe-noveling, the plugin that ships this one along with the rest of its 16 skills, 4 agents.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00556
Opus 5	$0.00013	$0.00278
Sonnet 5	$0.00005	$0.00111
Haiku 4.5	$0.00003	$0.00056

Security

Grade A, and why

novel-knowledge 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/knowledge_graph.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.

What it actually says

知识图谱工具

供其他 skill 调用，负责数据访问，不包含高层语义判断。

命令

python {SKILL_DIR}/scripts/knowledge_graph.py <command> [args]

search — 搜索设定

python {SKILL_DIR}/scripts/knowledge_graph.py search <query> [-t type] [-l limit] [-j]

update — 创建实体文件

python {SKILL_DIR}/scripts/knowledge_graph.py update <type> <name> [-j]

创建空模板文件，不覆盖已有文件。编辑完成后需运行 rebuild。

relations — 查询实体关系

python {SKILL_DIR}/scripts/knowledge_graph.py relations <entity_id>

返回出向和入向关系。

tags — 按标签查询

python {SKILL_DIR}/scripts/knowledge_graph.py tags <tag>

rebuild — 重建知识图谱（核心命令）

python {SKILL_DIR}/scripts/knowledge_graph.py rebuild

扫描 memory/entities/ 下所有 md 文件的 YAML frontmatter，重新生成 _graph.json 和 _index.json。

运行时机：创建新实体文件后、编辑实体 frontmatter 后、批量修改后、novel-sync 完成后。

实体文件格式

每个实体文件的 YAML frontmatter：

---
id: <唯一标识符，中文>
name: <显示名称>
type: <character/location/item/faction/concept>
tags: [标签1, 标签2]
relations:
  - target: <目标实体id>
    relation: <关系类型>
    description: <关系描述>
---

关系是双向的：A → B 的关系会自动生成 B → A 的入向关系。

依赖

PyYAML（解析嵌套 YAML frontmatter）：uv pip install pyyaml

Files

What ships with it

1 file 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.

novel-knowledge is a skill published in the GitHub repository TulanCN/vibe-noveling (23 stars, last pushed 3mo ago), licensed MIT. It adds 26 tokens to every session and 556 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
