Activation

This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.

Create polished, dependency-free architecture, workflow, sequence, data-flow, and lifecycle diagrams for Stacks applications as standalone HTML with inline SVG, dark/light themes, and PNG, JPEG, WebP, and SVG export. Use for system or cloud architecture, security boundaries, network topology, technical workflows, CI/CD, runbooks, API call sequences, request lifecycles, data pipelines, lineage, PII boundaries, state machines, status transitions, or converting Mermaid into a purpose-built diagram.

Key capabilities

  • Create architecture diagrams for system components and cloud resources
  • Generate workflow diagrams for technical flows and CI/CD processes
  • Produce sequence diagrams for API call chains and request lifecycles
  • Develop dataflow diagrams for pipelines and ETL processes
  • Design lifecycle diagrams for state machines and status transitions
  • Export diagrams as standalone HTML with inline SVG and dark/light themes

How it works

The skill uses renderers for different diagram types to generate self-contained HTML files with inline SVG, a theme toggle, and an export menu. It processes JSON input to create the visual representation.

Inputs & outputs

You give it
JSON data describing the diagram elements
You get back
a single self-contained .html file with inline SVG

When to use stacks-technical-diagrams

  • Documenting system architecture
  • Visualizing API call sequences
  • Mapping network topology
  • Creating CI/CD diagrams

About stacks-technical-diagrams

Builds standalone diagrams with dark/light theme support. It creates self-contained HTML files with exportable SVG/PNG assets for system architecture and workflows.

When not to use it

  • When the user wants to install packages or fetch runtime assets
  • When the user wants to render or parse Mermaid code mechanically
  • When Bun cannot run and a fallback to architecture mode is required

Limitations

  • Does not install packages or fetch runtime assets
  • Does not mechanically render or parse Mermaid code
  • Requires Bun to run the skill for full functionality

How it compares

This workflow generates dependency-free, self-contained HTML diagrams with built-in theming and export capabilities, unlike generic diagramming tools that may require external dependencies or produce less portable outputs.
