Mindmap PPT Builder

Goal

Turn a user-provided source document into a presentation-ready

project/source.js

for this repo. The source document may be pasted text in the conversation or a local text/Markdown file path supplied by the user. The output is a preorder mind-map: concise two-line nodes, optional node images, and local assets that match the current light PPT style.

Read

references/project-format.md

when you need exact project file conventions or visual constraints.

Workspace Requirement

Use this skill inside the

agegr/mindmap-ppt

repository root.

If the current directory already contains
```
package.json
```
,
```
index.html
```
,
```
src/
```
, and
```
project/
```
, treat it as the repo root.
If the repo is not present, clone
```
https://github.com/agegr/mindmap-ppt
```
into the current working directory as a folder named
```
mindmap-ppt
```
, then enter that folder.
If a
```
mindmap-ppt
```
path already exists but is not this repo, stop and ask the user where to place the clone.
Keep the application repository outside the skill folder. Do not copy or clone
```
index.html
```
,
```
src/
```
, or
```
project/
```
into
```
.agents/skills/mindmap-ppt-builder/
```
.
Normal skill output should modify only
```
project/source.js
```
and local asset files under
```
project/
```
.
Do not delete existing project assets unless the user explicitly asks for cleanup.
Do not edit
```
src/
```
,
```
index.html
```
, or application behavior unless the user explicitly asks for implementation changes.

Workflow

Get the user's source document:
- Use pasted text from the conversation when provided.
- If the user gives a local file path, read only that explicitly provided document file and use its contents.
- If neither pasted text nor a readable local file is available, ask the user for the document before generating
```
project/source.js
```
  .
Read the document and identify the presentation thesis.
- Follow the source language by default: Chinese input -> Chinese output; English input -> English output.
- For English output, still use an eyebrow/headline structure for two-line nodes when natural.
- Do not silently correct facts. If the source has obvious contradictions or questionable claims, preserve the claim carefully or mention the conflict to the user.
- For very long documents, preserve the original chapter structure first. If the material is too broad to reduce confidently, draft a high-level outline and ask the user to confirm priorities before finalizing.
Build a clear logic tree:
- root: document/source name or presentation topic
- major branches: usually 2-4 sections, but follow the source logic when another structure is clearer
- child nodes: use them for causes, consequences, evidence, examples, process steps, contrasts, or supplements
- depth: add levels only when nesting makes the author's logic easier to understand
Write each node as one unordered-list item plus an optional continuation line:

- 副标题
  主标题

Use the first line as a short category label and the second line as the main message. Keep each line under about 30 Chinese characters or 8 English words. Prefer two-line labels for all visible nodes; use a single-line node only when the label is already extremely short and clear.

Choose image nodes sparingly:
- Node images are optional.
- A mind-map necessarily omits a lot of source detail; use images to preserve or explain the omitted detail on high-information nodes.
- Pick 3-8 high-information nodes for a typical deck; short drafts may use 0-2 images.
- Prefer nodes that summarize a process, architecture, comparison, timeline, metric, or conceptual model.
Generate illustrations for chosen nodes with GPT Image 2 or the available image generation tool. Save them under
```
project/
```
or a subfolder of
```
project/
```
.
- Prefer PNG for generated raster illustrations, SVG for simple diagram placeholders, and JPG only for photo-like assets.
- If image generation is unavailable, either omit images or create simple SVG placeholder diagrams under
```
project/
```
  using the same restrained palette. Use 16:10 composition, no text inside images, and descriptive kebab-case filenames such as
```
project/demo-flow.svg
```
  .
Reference images in Markdown metadata lines:

  @image process-overview.png

Replace
```
project/source.js
```
with:

export const sourceMarkdown = `
- ...
`;

Escape backticks and

${...}

sequences before writing user-derived text inside the JavaScript template string.

Run
```
npm run check
```
.
Optional visual validation: run
```
npm run dev
```
and inspect
```
http://127.0.0.1:5173/
```
when browser inspection is available.

Mindmap Authoring Rules

Do not force every deck into a strict
```
root -> level 1 -> level 2 -> level 3
```
taxonomy. That shape is only a useful default, not a rule.
Let the hierarchy express the author's logic structure. If cause A leads to result B, B can be a child node of A; if B further leads to result C, form an
```
A -> B -> C
```
subtree.
The only hard principle is clarity: a reader should understand why each child node belongs under its parent and what relationship is being expressed.
Follow the source order. This app reveals nodes in preorder: parent first, then all children. Do not move conclusions from later text into earlier parent labels.
Do not repeat the root topic in child nodes. If the root already states the problem or theme, children should advance the story.
Group nearby meanings under one parent. Keep backgrounds, criteria, risks, product/tool inventories, recommendations, and conclusions in their own coherent branches.
Main nodes carry judgments; child nodes carry evidence, reasons, examples, or supplements. If a node explains another node, make it a child, not a sibling.
Keep each parent to at most 5 children. If there are more, add grouping nodes.
Split tools/products only when the source analyzes them one by one. Merge them when the source merely lists options in passing.
Do not split sentence by sentence. One node should carry one complete small point.
Each node should correspond to about 10-80 Chinese characters of source material. Less than 10 is usually too fragmented; more than 80 usually needs splitting.
Node text may be slightly longer than a normal title, but one node should not contain multiple independent ideas.
Parent labels should summarize and navigate; child labels should reveal specifics. Avoid parent labels that spoil later details.
Put images on high-information nodes, such as framework, comparison, inventory, recommendation, or risk-model nodes. Avoid images on very small detail nodes.

Markdown And Image Example

Use

@image

as a metadata continuation line after the node's visible two-line label. The

@image

line is not displayed as node text.

export const sourceMarkdown = `
- 产品发布
  三分钟讲清楚新功能
  @image overview.png
    - 用户痛点
      当前流程成本很高
      @image image-asset-1/pain-points.jpg
    - 解决方案
      自动整理文稿和插图
    - 演示效果
      像 PPT 一样逐步展开
      @image diagrams/demo-flow.svg
`;

Image paths are relative to

project/

by default:

@image overview.png

./project/overview.png

@image image-asset-1/pain-points.jpg

./project/image-asset-1/pain-points.jpg

@image diagrams/demo-flow.svg

./project/diagrams/demo-flow.svg

Image Prompt Pattern

Use this style prompt for GPT Image 2:

text

Create a clean presentation illustration for a light PPT mind-map node.
Subject: <node main idea>.
Include: <2-4 concrete visual elements from the source text>.
Style: restrained vector-like editorial illustration, warm off-white background, dark teal #183a4a, muted green #eef7f3, orange accent #d8894f, simple geometric shapes, thin shadows, small 8px-radius card-like forms, no photorealism, no text, no logos, no busy decorations.
Composition: centered, generous whitespace, readable at thumbnail size, aspect ratio 16:10.

If the source needs a real chart, diagram, or screenshot, create a simple diagrammatic illustration instead of inventing precise numbers. Do not put text in images; labels belong in nodes.

SVG Placeholder Pattern

When no image-generation tool is available but an illustration is still useful, a simple SVG placeholder is acceptable:

Size:
```
1280x800
```
.
Style: warm off-white background, dark teal
```
#183a4a
```
, muted green
```
#eef7f3
```
, orange accent
```
#d8894f
```
.
Content: abstract process blocks, arrows, cards, or timeline shapes based on the node idea.
No readable text, logos, dense decoration, or photorealism.

Authoring Rules

Preserve the user's argument. Do not flatten important causal relationships into generic slogans.
Keep the preorder reveal useful: each next node should add a clear idea.
Use
```
@image
```
only after the node's title line, before its children.
Use PNG, JPG/JPEG, or SVG assets.
Save image files under
```
project/
```
or a subfolder of
```
project/
```
.

Prefer short

@image

values relative to

project/

, e.g.

@image user-journey.png

@image diagrams/user-journey.png

, or

@image image-asset-1/a.jpg
