narrative-writing

narrative-writing is a cursor rule for Cursor from holycube/game-narrative-mcp. It costs 273 tokens per session, scanned A, original, MIT.

A set of rules for writing and editing video-game narratives, connected to a narrative project. It requires the agent to load the project's writing context and story canon, which is the established set of story facts, before making changes.

In plain words
What is it for?
Editing specified events or scenes, following a content guide, confirming story beats before writing long passages, checking scenes against the rules, and validating larger project changes.
Why use it?
It keeps edits within the project's tone, terminology, character voices, and established story, while requiring checks after scenes or project structure change.

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

narrative-writing 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 5d 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.

写作中

  • 只修改用户指定的事件 ID 或场景,不擅自新建结构(除非用户明确要求)
  • 遵守 content_bible 的基调、禁用词、角色 voice
  • 先结构后 prose:大段剧情先确认 beat / thread / scene

写作后

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.
