At a glance

Create comprehensive HTML architecture diagrams showing data flows, business objectives, features, technical architecture, and deployment.

  • Works in 6 steps: Business Context: objectives, users,… → Data Flow: sources → processing →… → Processing Pipeline: multi-stage… → …
  • Users request system architecture
  • SKILL.md covers When to Use, Components to Include, HTML Structure and SVG Pattern for Data Flow, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Architecture Diagram Creator is an agent skill from mhattingpete/claude-skills-marketplace. Create comprehensive HTML architecture diagrams showing data flows, business objectives, features, technical architecture, and deployment. Use when users request system architecture, project documentation, high-level overviews, or technical specifications.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets.

It sits in Development, covering Diagrams. The repository describes itself as: Claude Code Skills for software engineering workflows - Git automation, testing, and code review. The licence is Apache-2.0.

When your agent uses it

  • Users request system architecture
  • Project documentation
  • High-level overviews
  • Technical specifications

Example prompts

  • “/architecture-diagram-creator”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Business Context: objectives, users, value, metrics
  2. Data Flow: sources → processing → outputs with SVG diagram
  3. Processing Pipeline: multi-stage visualization
  4. System Architecture: layered components (data/processing/services/output)
  5. Features: functional and non-functional requirements
  6. Deployment: model, prerequisites, workflows

What it can do on your machine

Read from SKILL.md and the folder at commit b5b34bc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are html).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Architecture Diagram Creator loads about 676 tokens when it runs, and up to ~8.7k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 128 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~676
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SVG Pattern for Data Flow

html
<svg viewBox="0 0 800 400">
  <!-- Data sources (left, blue) -->
  <rect x="50" y="150" width="120" height="80" fill="#4299e1"/>

  <!-- Processing (center, orange) -->
  <rect x="340" y="150" width="120" height="80" fill="#ed8936"/>

  <!-- Outputs (right, green) -->
  <rect x="630" y="150" width="120" height="80" fill="#48bb78"/>

  <!-- Arrows connecting -->
  <path d="M170,190 L340,190" stroke="#666" stroke-width="2" marker-end="url(#arrow)"/>
</svg>

Workflow

  1. Analyze project (README, code structure)
  2. Extract: purpose, data sources, processing, tech stack, outputs
  3. Create HTML with all 6 sections
  4. Use semantic colors for visual hierarchy
  5. Write to [project]-architecture.html

Keep diagrams clear, use consistent styling, include real project details.
