description	How to create, read, and edit .mindmap files. Use this skill when the user asks to create a mindmap, brainstorm visually, map out ideas, or when working with existing .mindmap files.

Mindmap File Format

.mindmap files are standard markdown that Nimbalyst renders as an interactive mindmap. You can create and edit them directly -- no special tools needed.

Syntax

Tree structure

Syntax	Mindmap level
# Heading	Root node (exactly one per file)
## Heading	Depth 1 branches
### Heading	Depth 2 branches
- List item	Deeper nodes (indentation = depth)
- Nested item	2 spaces per indent level

Headings define the top 3 levels. Below that, indented list items handle arbitrary nesting.

Notes

Blockquotes immediately after a node become that node's note:

## Branch Name
> This note is attached to "Branch Name".
> It can span multiple lines.

Metadata

Inline {key: value} at the end of a node line:

- Task name {color: green, status: todo, tags: frontend, urgent}

Supported keys:

• color: default, red, orange, yellow, green, blue, purple, pink
• status: none, idea, question, todo, in-progress, done
• tags: comma-separated list

Frontmatter

YAML frontmatter stores the document title:

---
title: My Mindmap
---

# Project Plan

## Research {color: blue}
- User interviews {status: done}
- Competitive analysis {status: in-progress}
  - Feature comparison
  - Pricing analysis

## Design {color: purple}

### Wireframes
- Homepage {status: done}
- Dashboard {tags: priority}

### Prototypes
- Interactive prototype {status: todo}

## Engineering {color: green}
- API design
  > RESTful endpoints for the core product.
  - Authentication
  - Data models
- Frontend
  - Component library
  - State management

Rules

1. Exactly one # heading (the root node)
2. ## and ### for the top levels, then - lists for deeper nesting
3. 2 spaces per indent level for list items
4. Metadata {...} goes at the end of the node line, not on a separate line
5. Notes > ... go on the line(s) immediately after the node they belong to
6. Blank lines between sections improve readability but are optional
7. The file extension is .mindmap (not .md)
