furina: Instructions file for Codex

AGENTS.md

furina AGENTS.md is an instructions file for Codex, OpenCode from Furinelle/furina. It costs 642 tokens per session, scanned A, original, MIT.

Repository instructions for maintaining a Furina role-playing agent skill, including its source material, response rules, memory handling, and tests. A skill is a packaged set of instructions for an AI coding agent.

In plain words
What is it for?
Answering role-playing prompts, maintaining the Furina skill package, saving or reading its memory, and running tests after changes.
Why use it?
They keep the role, reference material, memory, and platform-specific entry points consistent while preventing unsupported character details or unsafe memory storage.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is Furinelle/furina's own configuration. It tells Codex and OpenCode how to work on furina itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything furina configures →

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

furina AGENTS.md 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 7d 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

Furina Roleplay — Agent 指南

本仓库是一个遵循 Agent Skills 开放标准 的角色扮演 skill 包。唯一的规范 skill 位于 skills/furina/(自包含:SKILL.md + references/ + scripts/ + assets/),适用于任何支持该标准的 agent。

使用

  • 角色扮演 / 设定问答:读 skills/furina/SKILL.md 并遵循其路由,按需加载 1-2 个 reference 文件,不要整库加载。
  • Claude Code 项目内可直接用 /furina.claude/skills/ 下是薄入口,规范内容始终在 skills/furina/)。
  • 记忆读写优先用 node skills/furina/scripts/furina-memory.mjs(Node ≥ 18,零依赖)。

维护原则

  • skills/furina/references/furina_resource/ 是唯一角色资料源;references/prompt/_shared_runtime.md 是崩坏梯度、自称切换、灵魂状态、反应公式与回复分寸的唯一运行时维护点。
  • 敏感话题分寸(表白亲密度分级、关系话题写法)的唯一维护入口是 references/furina_resource/11_sensitive_topics.md05_voice_style.md 只保留分析性说明,不重复表格。
  • 破绽句式见 references/furina_resource/07_quotes.md;语气验收用例见 references/eval/furina_voice_cases.md(含多轮漂移脚本)。
  • skill 必须保持自包含:skills/furina/ 内部只用相对路径,不引用仓库其他位置;平台专属内容(frontmatter 扩展字段、斜杠命令糖)只放在对应平台目录(如 .claude/skills/),不进入规范 skill。
  • 不编造官方设定;资料未覆盖的内容联网查证后标注为参考/推断。资料时效声明见 references/furina_resource/03_story_timeline.md 版本足迹小节。
  • 改动后运行 node --test 验证(含人设内容回归断言)。

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.
