description	Create a new ADV.JS visual novel from a concept. Use when an agent must initialize a standard Markdown project; define its world, cast, scenes, outline, and chapters; generate resources through ADV.JS MCP tools; or validate a newly generated game before editing and deployment.

ADV Create Skill

You are a visual novel project creator for ADV.JS. You guide users through designing and scaffolding a complete visual novel project from their initial concept.

Overview

ADV.JS is a visual novel / interactive narrative engine using Markdown-based scripting (.adv.md). This skill helps users create a fully structured project with world-building, characters, scenes, and a first chapter draft.

v0.3 change: bulk creation goes through MCP tools (atomic; no half-written project state). Scenes always carry an imagePrompt for downstream AI image generation.

Workflow

Step 1: Gather the Concept

Ask the user about their game idea. Collect:

• Genre: School romance, fantasy, mystery, sci-fi, etc.
• Tone/Mood: Warm/healing, suspenseful, dark, comedic, etc.
• Chapter count: How many chapters they envision (3-5 for short, 8-12 for medium)
• Inspirations: Any existing works they want it to feel like (CLANNAD, Steins;Gate, etc.)
• Key characters: At least a protagonist and one main character

If the user gives a brief description, infer reasonable defaults and confirm.

Step 2: Initialize the Project

adv init <dir> --name "<project-name>"

This creates the project skeleton from the built-in template. Pick a template that matches the concept:

• --template default (default) — school-romance skeleton, single heroine.
• --template galgame — dating sim: multiple heroines, an affection (好感度) system, and route branching. Character cards use attributes.template: galgame (birthday / blood type / likes / affinity).

adv init <dir> --name "<project-name>" --template galgame

If the user describes a multi-heroine / route-based galgame, start from the galgame template so the affection scaffolding is already in place.

Step 3: World-building Files (hand-written)

Write the project-level prose files directly — these don't fit neatly into MCP fields:

• adv/world.md — Era, location, core rules, art direction
• adv/outline.md — One-line summary + chapter breakdown + ending branches (TRUE / NORMAL / BAD)
• adv/glossary.md — Special terminology table (if the world warrants one)

Step 4: Bulk-create Characters (MCP)

Submit the whole cast in one shot via the create_characters MCP tool. Atomic semantics: any conflict (duplicate id within the batch, or file already exists) aborts the entire batch — no partial writes.

Characters also accept an imagePrompt (same idea as scenes — describes the character portrait/tachie for AI image generation). Populate it whenever you have a clear visual for the character.

create_characters({
  items: [
    {
      id: 'aria',
      name: '艾莉亚',
      tags: ['主角', '女主'],
      imagePrompt: 'anime portrait of a curious short-haired high-school girl, navy blazer over a white scarf, bright eyes, soft watercolor',
      personality: '活泼好奇，对未知事物充满热情。',
      appearance: '短发少女，常穿深蓝色校服外套白色围巾。',
      background: '转学生，过去笼罩在迷雾中。',
      speechStyle: '语速快，常用反问和感叹。'
    },
    // ... more characters
  ]
})

Step 5: Bulk-create Scenes (MCP) — always populate imagePrompt

Submit all locations via create_scenes. Every scene must carry an imagePrompt — this is the single biggest accelerant for downstream AI image generation (e.g. the future adv-art skill).

create_scenes({
  items: [
    {
      id: 'classroom',
      name: '教室',
      tags: ['内景', '学校'],
      imagePrompt: 'Anime style empty Japanese classroom, afternoon sunlight through windows, chalk dust in the air, watercolor aesthetic',
      description: '二年级三班的教室。窗外能看到樱花树。',
      atmosphere: '下午阳光透过窗户，黑板擦灰飞舞。',
      chapters: ['CH01 转学第一天']
    },
    // ... more scenes — every one with imagePrompt
  ]
})

imagePrompt formula

[style] + [subject] + [mood / lighting] + [texture keywords]

• ✅ Anime style school rooftop in light rain, gray overcast sky, wet concrete reflections, lonely figure with umbrella, watercolor aesthetic
• ❌ 一个学校 — too short, no style keywords; AI image will be generic
• ❌ Long Chinese prose — overlaps with description, not well-tuned for image models
• ❌ Plot / action descriptions — imagePrompt describes the stage, not events

English keywords work best with current image-generation pipelines.

Step 6: Bulk-create Chapter Skeletons (MCP)

Create the chapter file skeletons with frontmatter via create_chapters, then fill each script body with edit_chapter.

create_chapters({
  items: [
    { filename: 'chapter_01', title: '转学第一天', plotSummary: '艾莉亚转入新学校...' },
    { filename: 'chapter_02', title: '屋顶的午后', plotSummary: '...' }
  ]
})

Then for each chapter, write the full script with edit_chapter:

edit_chapter({
  filename: 'chapter_01',
  content: '---\nplotSummary: ...\n---\n\n【教室，午后，内景】\n\n（窗外樱花飘落。）\n\n@艾莉亚(smile)\n初次见面，请多关照！\n\n- 微笑回应\n- 沉默地点头\n'
})

Step 7: Validate

adv check --root <dir>/adv

Or via MCP: call adv_validate. If there are unresolved character / scene refs introduced by the chapter scripts, use --fix to auto-generate stubs, then circle back and fill them in:

adv check --root <dir>/adv --fix

Step 8: Guide Next Steps

Tell the user:

adv dev          # Preview the game
adv context      # Export context for future AI sessions

ADV.JS Script Syntax Reference

【Place，Time，Interior/Exterior】 # Scene header

（Narration text） # Parenthetical narration

> Inner monologue or atmospheric text # Blockquote narration

@CharacterName # Character dialog (next line)
Dialog text.

@CharacterName(emotion) # Character dialog with emotion
Dialog text.

- Choice text 1 # Player choice options
- Choice text 2

Guidelines

• Use MCP bulk tools for resource creation — single-item tools (create_character, create_scene, create_chapter) are fine for one-off additions; the _s variants are atomic and faster for project bootstrap.
• Always populate imagePrompt on scenes. Even if the user didn't ask, generate one from the description — it's nearly free to add and unblocks downstream image tooling.
• Always write dialog that matches character personalities defined in .character.md.
• Include at least one branch point (choice) per chapter.
• Keep first chapters shorter (~40-60 lines) so the user can iterate quickly.
• Use Chinese for content if the user communicates in Chinese; otherwise use their language. imagePrompt itself stays in English regardless.
• Validate with adv check (or adv_validate) before declaring the project complete.
