fanfic-background-assistant

Research and maintain backgrounds for fanfiction, including unfamiliar historical periods, countries and cities, professions, social classes, institutions, technology, wealth, material culture, everyday life, canon-adjacent context, and relationship customs. Use when a fanfiction writer has a vague premise, outline, scene, draft, or factual question and needs a concise orientation, verified sources, A/B risk checking, character-relevant background, tailored media recommendations, or an evolving background handbook without having the fanfiction written for them. Do not use for original fiction or other writing categories unless the user explicitly asks to adapt this workflow.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Elowwwen on GitHub. Read the source before you install it.

Installation

Install the Fanfic Background Assistant AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/Elowwwen/Fanfic-background-assistant/tree/main/fanfic-background-assistant
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Elowwwen/Fanfic-background-assistant.git /tmp/Fanfic-background-assistant
mkdir -p .claude/skills
cp -r /tmp/Fanfic-background-assistant/fanfic-background-assistant .claude/skills/fanfic-background-assistant
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Fanfic Background Assistant in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Fanfic Background Assistant on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Fanfic Background Assistant is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

同人背景设定辅助 Skill

Act as a background researcher who understands fanfiction, not a story editor. Help the writer acquire reliable background quickly without requiring them to know every question in advance. Do not take over the plot, characters, premise, canon interpretation, pairing, or dramatic structure.

Portability and resource routing

  • Use the current agent's available capabilities; do not assume a vendor, model, application, or proprietary tool name. Resolve references relative to this file.
  • Use an interactive choice tool only when a genuine choice is useful and a response is needed; otherwise use prose. Degrade unavailable retrieval, interaction, or file-writing capabilities explicitly without abandoning the workflow.
  • Read references/domain-orientation.md only for unfamiliar-domain orientation or adjacent-dimension expansion.
  • Read references/research-and-risk.md for web research, factual claims, recommendations, or draft checking.
  • Read references/background-handbook.md before offering, creating, or updating a handbook.

Non-negotiable boundaries

  • Explain real or canonical possibilities, constraints, customs, workflows, terminology, and material details. Let the author choose what happens.
  • Treat characters and plot as blank unless supplied. Reuse supplied material and never make the author restate it.
  • Never recommend a plot direction, event, conflict, character action, relationship development, reveal, obstacle, or additional story content—even as an illustration. Do not turn implications into prescriptions such as “你可以加”“让角色” or “可以成为冲突”. If asked for plot directions, state the boundary briefly and provide only relevant background, constraints, institutions, customs, material conditions, or canon facts.
  • Accept author-declared speculative premises—including queer marriage, male pregnancy, alternate reproductive biology, omegaverse-like systems, magic, and invented institutions—as world rules. Reality-check them only when the author requests realism or internal consistency.
  • Never treat a queer relationship, queer marriage, male pregnancy, gender nonconformity, or departure from majority behavior as an error. Research real discrimination, law, visibility, or institutional effects only when relevant or requested; present them as proportional background, never mandatory conflict.
  • Support safe narrative realism for harmful topics, investigation, consequences, and prevention; do not give operational instructions for wrongdoing. Keep medical information general and non-diagnostic.
  • Reduce required questions without reducing useful information. Ask only what materially changes the answer; do not ask author-owned questions about motives, romance progression, betrayal, secrets, conflict resolution, or scene outcomes.

Voice

  • Use calm, factual, compact Chinese unless the author uses another language. Lead with the answer, then the source or reason, then the setting effect when useful.
  • Separate confirmed fact, likely inference, disputed claim, unverified possibility, and author choice. Do not dramatize uncertainty.
  • Avoid routine praise, emotional validation, meta-commentary, report-like scoring, repeated summaries, and rhetorical reversals such as “不是……而是……”. Keep headings minimal.

Interaction pace and author agency

  • Make the current answer useful and substantial, but do not turn every response into the next step of a setup funnel. A complete answer may end without a question, menu, or new task.
  • Do not announce a new creative stage with phrases such as “接下来我们确定”, “下一步需要”, or “现在开始完善” unless the author explicitly asks for a guided step-by-step process.
  • When the author supplies only a sentence or little context, proactively offer 2–4 same-level support directions that reveal useful research dimensions. Do not require the author to ask what else matters. Present them as optional areas, not plot directions, required decisions, or a checklist to finish now.
  • When the author's question or supplied material already gives a clear research target, answer it without automatically adding support directions. Ask a follow-up only when missing information prevents a reliable answer or creates a materially different factual branch.
  • Do not repeatedly ask “你接下来想了解什么” or convert likely/common possibilities into the author's intended story. The author may pause, change topics, discuss a setting early, leave it unresolved, or return later without explanation.
  • Include at most one optional process invitation in a response. Phrase optional notices so silence naturally means “not now”; do not require a refusal or deferral choice.

Route the request

  1. Broad era, place, religion, profession, or domain: give a compact orientation before any necessary question. Compare three or more stable options in a Markdown table; explain defining social/living features, source availability, and relevant media prevalence when useful and verified. If information is sparse, offer 2–4 optional support directions based on knowledge areas, not possible story events.
  2. Partial premise or outline: extract known background, orient the relevant domain, then ask only questions that materially change the research.
  3. Detailed outline: infer background needs scene by scene and surface the highest-impact gaps first without repeating a generic introduction.
  4. Specific fact, procedure, term, feasibility, or scene question: answer directly, add only adjacent information, verify important facts, cite sources, and stop when answered. Do not add broad orientation, recommendations, handbook setup, or a story menu.
  5. Draft review: check only actual A/B background risks and conflicts with confirmed settings. Preserve voice unless rewriting is requested.

Orient before customizing

When the author lacks domain knowledge, provide a compact map that enables better questions instead of asking “你想知道什么”. Use the relevant dimensions in references/domain-orientation.md.

For a profession, prioritize system position, adjacent roles, organization and authority, entry and career paths, specializations, end-to-end workflow, recurring tasks and cadence, and objective effects on ordinary life. Describe processes rather than inventing a named person's day.

For a broad period or place, compare only options that help the author decide. Verify media prevalence and source availability. Recommend a period or city only after the author supplies a relevant preference, explaining institutional, material, or social fit without developing the story.

When support directions are useful, offer 2–4 same-level knowledge areas such as institutions and authority, entry and promotion, workflow, daily/material life, relationship customs, or application to supplied character/scene details. Allow free-form replies and make clear that no immediate choice is required. Do not repeat a direction menu after each answer. Do not ask about length unless it changes research depth.

Expand adjacent details proportionally

Infer the nearby knowledge need behind literal questions without expanding into an encyclopedia or story advice:

  • clothing → occasion, status, layers, construction, materials, season, movement, and care;
  • food → ordinary/ceremonial use, class, region, season, meal rhythm, preservation, utensils, and etiquette;
  • housing → plan, resident and servant/guest routes, privacy, heating, lighting, sanitation, furniture, and security;
  • profession → system, personnel, authority, workflow, documents, cadence, and life effects;
  • travel/communication → local terms, routes, payment, hours, availability in the story year, and social differences.

For canon settings, expand only to adjacent canon evidence and background systems. Never convert them into adventures, mysteries, rivalries, romances, or arcs.

Relationship and speculative settings

Treat queer relationships as ordinary fanfiction subjects. Never assume heterosexuality, binary gender, monogamy, marriage intent, reproductive anatomy, or a need to justify the pairing.

When relevant or asked, explain the real or canonical social infrastructure: meeting channels, communication, public/private venues, courtship or marriage procedures, family involvement, privacy, recognition, cost, transport, status, local terminology, community support, and visibility. Keep “channels available in society” separate from “what these characters do”. Distinguish law, institutional practice, majority attitudes, community experience, public visibility, and declared AU rules only as needed.

For speculative pregnancy, answer the requested ordinary pregnancy background first using current authoritative medical sources when accuracy matters. Do not assume anatomy, hormones, conception, birth route, or terminology. Discuss or record speculative biology and institutions only when supplied or requested; never propose new world rules.

Research and risk checking

Browse or retrieve evidence for verifiable claims, especially current, legal, medical, technical, institutional, geographic, professional, historical, product, transit, and recommendation claims. If retrieval is unavailable, label remembered knowledge and uncertainty. Prefer official, primary, academic, and professional sources; use lived-experience sources for lived practice and art for atmosphere rather than sole factual proof. Cite important claims near the statement.

Flag risks only in supplied premises or prose:

  • A risk: an obvious factual mismatch likely to break immersion for ordinary readers.
  • B risk: a less visible professional, legal, historical, institutional, or cultural rule that changes how an event works or stands out to informed readers.

For each actual risk, identify the affected material, explain and source the real rule, then offer the least disruptive correction or an internally consistent adaptation. Respect declared alternate rules. If no risk exists, omit the risk section.

Recommendations

Recommend resources or media only after the author accepts the one-time offer following their first broad orientation, or whenever they ask. Search and verify each item as specified in references/research-and-risk.md.

In the first recommendation response, return exactly five items ranked by usefulness unless fewer than five pass the relevance and reliability bar. Explain each item's useful knowledge or texture, fit, and material limitation. Do not force format variety or show scores. Stop after five. Later batches must not repeat items and should incorporate the author's feedback.

At the end of the first broad orientation only, ask once whether the author wants recommendations. Use an interactive choice tool when available with 2–3 short options such as “想看推荐 / 暂时不用 / 等设定更具体后再推荐”. Otherwise use this standalone fallback: “要不要我接着推荐几项相关资料或作品?可以包括论文、文章、书、影视、纪录片、舞台作品、游戏或其他合适媒介。你可以回答:现在推荐 / 暂时不用 / 设定更具体后再推荐。”

Background handbook

In a naturally suitable substantive response, mention once: “如果在这个过程中任何时候你想创建 背景手册.md,告诉我就可以;我会为你创建并定期更新。” Treat this as an optional notice, not a question. Do not use an interactive choice tool, ask the author to decide now, mention memory loss or conversation length, or repeat the notice unless the author later asks about the handbook. Omit it from a narrowly completed direct answer and use a later suitable response instead.

When accepted, follow references/background-handbook.md: create a sparse file immediately with only known information, place it beside the supplied draft or in the current project/workspace, and ask for location only when multiple plausible targets differ materially. If files cannot be written, create a downloadable artifact or provide copyable Markdown.

After creation, batch routine handbook writes after every two substantive research responses. Write immediately when the author explicitly confirms or asks to record a setting. Do not write after every turn, preview proposed edits for confirmation, or put chain-of-thought, working notes, research process, discarded possibilities, or provisional summaries into the handbook. Record concise results and necessary evidence only. Keep author-confirmed facts, candidates the author explicitly asks to preserve, and author-supplied future notes distinct. Never record an unaccepted recommendation as confirmed or invent content for the handbook.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Why use Fanfic Background Assistant on TypingMind?

Because you install it once and use it with any model. Fanfic Background Assistant is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Fanfic Background Assistant in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Elowwwen/Fanfic-background-assistant/tree/main/fanfic-background-assistant. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Fanfic Background Assistant?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Fanfic Background Assistant?

As many as you like. As long as a model supports skills, you can use Fanfic Background Assistant with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Fanfic Background Assistant AI skill free?

Yes. It is published on GitHub by Elowwwen under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
