architecture-diagram

architecture-diagram is a skill for Claude Code, Codex from S3YED/appie-kit. It costs 15 tokens per session (1,505 once invoked), scanned A, a copy of architecture-diagram, MIT.

A tool for drawing dark-themed SVG diagrams of software systems, cloud infrastructure, services, databases, and deployment layouts. SVG is a web image format that keeps diagrams sharp when resized.

In plain words
What is it for?
It helps map frontend, backend, and database layers, cloud networks, microservices, service meshes, APIs, and deployment environments.
Why use it?
It makes technical relationships and infrastructure easier to see than a long written description or scattered notes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

architecture-diagram scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architecture Diagram Skill

Generate professional, dark-themed technical architecture diagrams as standalone HTML files with inline SVG graphics. No external tools, no API keys, no rendering libraries — just write the HTML file and open it in a browser.

Scope

Best suited for:

  • Software system architecture (frontend / backend / database layers)
  • Cloud infrastructure (VPC, regions, subnets, managed services)
  • Microservice / service-mesh topology
  • Database + API map, deployment diagrams
  • Anything with a tech-infra subject that fits a dark, grid-backed aesthetic

Look elsewhere first for:

  • Physics, chemistry, math, biology, or other scientific subjects
  • Physical objects (vehicles, hardware, anatomy, cross-sections)
  • Floor plans, narrative journeys, educational / textbook-style visuals
  • Hand-drawn whiteboard sketches (consider excalidraw)
  • Animated explainers (consider an animation skill)

If a more specialized skill is available for the subject, prefer that. If none fits, this skill can also serve as a general SVG diagram fallback — the output will just carry the dark tech aesthetic described below.

Based on Cocoon AI's architecture-diagram-generator (MIT).

Workflow

  1. User describes their system architecture (components, connections, technologies)
  2. Generate the HTML file following the design system below
  3. Save with write_file to a .html file (e.g. ~/architecture-diagram.html)
  4. User opens in any browser — works offline, no dependencies

Output Location

Save diagrams to a user-specified path, or default to the current working directory:

./[project-name]-architecture.html

Preview

After saving, suggest the user open it:

# macOS
open ./my-architecture.html
# Linux
xdg-open ./my-architecture.html

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
