architecture-diagram
by Cocoon-AICreate polished, dark-themed architecture diagrams as standalone HTML files with inline SVG. The architecture-diagram skill is built for system architecture, infrastructure, cloud, security, and network topology diagrams, giving you a browser-ready visual with semantic colors, clear component relationships, and a consistent technical style.
This skill scores 76/100, which means it is a solid but not exceptional listing candidate: directory users have enough evidence to install it if they want a focused architecture-diagram generator, but they should expect a somewhat template-driven workflow rather than a deeply guided tool. The repository clearly defines when to use it, what output it produces, and includes a reusable HTML template, so it offers real install decision value.
- Strong triggerability: the frontmatter explicitly says to use it for system, infrastructure, cloud, security, and network architecture diagrams.
- Operationally concrete: SKILL.md describes self-contained HTML output with inline SVG/CSS and includes a template asset for implementation.
- Good structure for agents: the skill body is substantial, uses headings/code fences, and includes design constraints and component-type color rules that reduce guesswork.
- Workflow depth appears limited: there are no scripts, references, or rule files to support more advanced or automated generation behavior.
- Adoption may rely on following an HTML template rather than a fully articulated end-to-end diagramming procedure, so users may need to supply more prompting context for complex diagrams.
Overview of architecture-diagram skill
The architecture-diagram skill helps you turn a rough system description into a polished, dark-themed architecture diagram as a self-contained HTML file with inline SVG. It is a good fit when you need a clear visual for service boundaries, data flow, cloud components, security layers, or network topology rather than a generic presentation slide.
This architecture-diagram skill is most useful for engineers, product teams, and technical writers who want a diagram that is readable, consistent, and easy to share without extra build steps. The main value is speed plus structure: it gives you a visual system, a color language, and an output format that can be opened directly in a browser.
What the architecture-diagram skill is for
Use architecture-diagram when the output must communicate relationships between components, not just list them. It is especially strong for:
- microservice and API layouts
- cloud or AWS-style architecture views
- security and trust-boundary diagrams
- data pipeline and message bus flows
- internal platform overviews
What makes it different
The repo is opinionated about presentation: dark theme, JetBrains Mono, semantic colors by component type, and SVG-first rendering inside HTML. That means the architecture-diagram skill is less about freeform illustration and more about producing consistent, technical diagrams that look production-ready.
When it may not fit
If you need editable diagrams in tools like Lucidchart or diagrams with heavy icon libraries, this may be the wrong fit. The skill is better for browser-rendered deliverables where clarity, portability, and a technical aesthetic matter more than drag-and-drop editing.
How to Use architecture-diagram skill
Install and load it cleanly
For architecture-diagram install, add the skill first and then read the skill instructions before drafting your prompt:
npx skills add Cocoon-AI/architecture-diagram-generator --skill architecture-diagram
After install, open SKILL.md and assets/template.html first. Those two files show the core layout rules and the output structure the skill expects.
Give the skill a complete system brief
The architecture-diagram usage works best when your input names the system, the main components, and the relationship between them. A strong prompt usually includes:
- the business or system name
- frontend, backend, database, and cloud services
- trust boundaries or security zones
- primary request/data flow
- any must-show technologies or labels
Example prompt shape:
Create an architecture diagram for a SaaS app with React frontend, Node API, Postgres, Redis cache, AWS ECS, S3, and Stripe. Show login, API calls, async jobs, and security boundaries.
Read the repo files in the right order
For an architecture-diagram guide that actually improves output, do not stop at the title. Start with:
SKILL.mdfor conventions and component mappingassets/template.htmlfor the visual scaffold and class names- any inline examples in the skill body for layout or label density
This order matters because the skill’s value is in how it encodes presentation choices, not in a large file tree.
Optimize the workflow for diagram quality
A practical workflow is: define scope, list components, map data flow, then generate. If your source material is messy, rewrite it into a simple inventory first. The architecture-diagram skill handles cleaner inputs better than vague architecture dumps. Give it explicit priorities such as “show the external boundary,” “emphasize the event bus,” or “keep database internals minimal” so the diagram does not become crowded.
architecture-diagram skill FAQ
Is architecture-diagram only for cloud diagrams?
No. The architecture-diagram skill is broader than cloud architecture. It also works for application stacks, internal platforms, security views, and network diagrams as long as the output is a component relationship map.
Do I need to know diagram syntax first?
No. This skill is useful precisely because it turns a plain-language system description into a structured visual. You do need to supply the right details, but you do not need to write diagram code manually.
How is this better than a normal prompt?
A normal prompt may produce a one-off diagram idea. The architecture-diagram skill adds a reusable design system, output format discipline, and a clearer path to a browser-ready result. That makes it easier to get consistent diagrams across projects.
When should I not use it?
Do not choose architecture-diagram if your main need is collaborative editing, architecture decision records with lots of prose, or highly customized vector art. It is a fit when the deliverable is a clean technical diagram, not a full documentation suite.
How to Improve architecture-diagram skill
Start with the decision you want the diagram to support
The best results come from prompts that say what the diagram should help a reader understand. For example, ask for “request path and failure points,” “security zones and data exposure,” or “service dependencies for onboarding.” That gives the architecture-diagram skill a hierarchy instead of a flat list.
Provide constraints, not just components
Users care most about clarity, and clutter is the main failure mode. Tell the skill what to omit, compress, or group. Good constraints include:
- “combine internal workers into one box”
- “avoid vendor logos”
- “limit to 6 core boxes”
- “show only user-facing flow, not every background job”
This is one of the fastest ways to improve architecture-diagram usage results.
Iterate from layout problems, not vague dissatisfaction
If the first output is weak, diagnose the issue precisely. Ask for a narrower scope, clearer labels, or a different grouping strategy. For example:
- too dense: reduce labels and merge low-value services
- unclear flow: number the steps and add arrows
- weak emphasis: highlight one path with stronger contrast
- missing context: add boundary labels and external dependencies
Use the template to keep outputs consistent
The assets/template.html file is especially useful when you need repeatable branding or a shared diagram style across multiple systems. Reusing that structure helps the architecture-diagram skill stay visually consistent while still allowing different component maps and labels.
