TreeListy Skill

TreeListy is your hierarchical decomposition engine. When you need to break down a complex topic, plan a project, or structure information in a tree format, use TreeListy.

When to Use This Skill

Use TreeListy when:

• Decomposing complex tasks — Break a large goal into phases, items, and actionable tasks
• Project planning — Create WBS, roadmaps, or strategic plans with proper hierarchy
• Structuring analysis — Organize arguments (philosophy), dialogues, or knowledge bases
• Content organization — Plan books, courses, theses, or event schedules
• Visual documentation — Generate Mermaid diagrams for any hierarchical structure

Quick Start

# List available patterns
node scripts/treelisty-cli.js patterns

# Create a structured decomposition
node scripts/treelisty-cli.js decompose --pattern wbs --input "Build a mobile app"

# Export to Mermaid diagram
node scripts/treelisty-cli.js export --input tree.json --format mermaid

The 21 Patterns

Commands

patterns — Discover available patterns

# List all patterns
node scripts/treelisty-cli.js patterns

# Get details for a specific pattern
node scripts/treelisty-cli.js patterns --name philosophy

# Get full JSON schema
node scripts/treelisty-cli.js patterns --name philosophy --detail

decompose — Create structured trees

Takes text input (topic, outline, or structured text) and applies a pattern template.

# Simple topic
node scripts/treelisty-cli.js decompose \
  --pattern roadmap \
  --input "Q1 Product Roadmap for AI Assistant" \
  --format json

# From structured input (markdown headers, indented lists)
echo "# Marketing Campaign
## Research Phase
- Market analysis
- Competitor review
## Execution Phase
- Content creation
- Launch ads" | node scripts/treelisty-cli.js decompose --pattern strategy --format json

# Output as Mermaid
node scripts/treelisty-cli.js decompose \
  --pattern wbs \
  --input "Website Redesign Project" \
  --format mermaid

Options:

• --pattern — Pattern to apply (default: generic)
• --input — Topic text, file path, or stdin
• --name — Override root node name
• --depth <1-4> — Maximum tree depth
• --format — Output: json, markdown, mermaid

export — Convert trees to other formats

# To Markdown
node scripts/treelisty-cli.js export --input tree.json --format markdown

# To Mermaid diagram
node scripts/treelisty-cli.js export --input tree.json --format mermaid

# To CSV
node scripts/treelisty-cli.js export --input tree.json --format csv

# To checklist
node scripts/treelisty-cli.js export --input tree.json --format checklist

Formats: json, markdown, mermaid, csv, checklist, html

validate — Check tree quality

# Human-readable report
node scripts/treelisty-cli.js validate --input tree.json

# JSON report
node scripts/treelisty-cli.js validate --input tree.json --format json

Returns:

• Quality score (0-100)
• Structure analysis (node counts, depth, balance)
• Issues (errors, warnings, suggestions)
• Pattern compliance check

push — Send to live TreeListy (optional)

If the user has TreeListy open in their browser with MCP bridge enabled:

node scripts/treelisty-cli.js push \
  --input tree.json \
  --port 3456

This displays the tree in TreeListy's visual canvas for interactive exploration.

Tree Data Model

Trees follow this structure:

{
  "id": "n_abc12345",
  "treeId": "tree_xyz78901",
  "name": "Project Name",
  "type": "root",
  "pattern": "roadmap",
  "icon": "🚀",
  "description": "Optional description",
  "expanded": true,
  "children": [
    {
      "name": "Phase 1",
      "type": "phase",
      "items": [
        {
          "name": "Feature A",
          "type": "item",
          "patternType": "Core Feature",
          "subtasks": [
            {
              "name": "Implement login",
              "type": "subtask"
            }
          ]
        }
      ]
    }
  ]
}

Hierarchy: Root → Phases (children) → Items (items) → Subtasks (subtasks)

Each pattern adds custom fields. For example, roadmap adds storyPoints, userImpact, technicalRisk.

Workflow Example

1. Agent receives complex task from user

1. Decompose with appropriate pattern:

```bash

node scripts/treelisty-cli.js decompose \

--pattern wbs \

--input "Build an e-commerce platform with user auth, product catalog, shopping cart, and checkout" \

--format json > project.json

```

1. Validate the structure:

```bash

node scripts/treelisty-cli.js validate --input project.json

```

1. Export for user consumption:

```bash

node scripts/treelisty-cli.js export --input project.json --format mermaid

```

1. Share the Mermaid diagram in response to user.
