NW-DIAGRAM: Architecture Diagram Generation

Wave: CROSS_WAVE | Agent: Morgan (nw-solution-architect) | Command: *create-diagrams

Overview

Context Files Required

docs/product/architecture/brief.md (SSOT — component boundaries, technology stack, design decisions)

Workflow

Read Context — Load docs/product/architecture/brief.md. Extract component boundaries, technology stack, and design decisions. Gate: architecture brief loaded.
Resolve Configuration — Determine diagram_type (component|deployment|sequence|data|context), format (mermaid|plantuml|c4), level (context|container|component), and output_directory. Gate: all configuration parameters resolved.
Invoke Agent — Delegate to @nw-solution-architect with *create-diagrams for {architecture-component}, passing context files and resolved configuration. Gate: agent invoked with all parameters.
Validate Output — Verify diagrams render without syntax errors and files exist in output_directory. Gate: all success criteria pass.
Handoff — Return deliverables to invoking agent. Gate: architecture diagrams available in configured format.

Success Criteria

[ ] Diagrams accurately represent current architecture
[ ] Audience-appropriate detail level applied
[ ] Diagrams render without syntax errors
[ ] Output files created in configured directory

Next Wave

Handoff To: {invoking-agent-returns-to-workflow}

Deliverables: Architecture diagrams in configured format

Examples

Example 1: Generate C4 container diagram

/nw-diagram payment-service --diagram_type=component --format=mermaid --level=container

Morgan reads architecture docs and produces a Mermaid container diagram showing service boundaries, data stores, and external integrations.

XLSX

by anthropics

vendor ×15

Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When Claude needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in my downloads\") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

Picks random winners from lists, spreadsheets, or Google Sheets for giveaways, raffles, and contests. Ensures fair, unbiased selection with transparency.

Query openFDA API for drugs, devices, adverse events, recalls, regulatory submissions (510k, PMA), substance identification (UNII), for FDA regulatory data analysis and safety research.

MATLAB and GNU Octave numerical computing for matrix operations, data analysis, visualization, and scientific computing. Use when writing MATLAB/Octave scripts for linear algebra, signal processing, image processing, differential equations, optimization, statistics, or creating scientific visualizations. Also use when the user needs help with MATLAB syntax, functions, or wants to convert between MATLAB and Python code. Scripts can be executed with MATLAB or the open-source GNU Octave interpreter.

UMAP dimensionality reduction. Fast nonlinear manifold learning for 2D/3D visualization, clustering preprocessing (HDBSCAN), supervised/parametric UMAP, for high-dimensional data.

Creating interactive data visualisations using d3.js. This skill should be used when creating custom charts, graphs, network diagrams, geographic visualisations, or any complex SVG-based data visualisation that requires fine-grained control over visual elements, transitions, or interactions. Use this for bespoke visualisations beyond standard charting libraries, whether in React, Vue, Svelte, vanilla JavaScript, or any other environment.

How to use it

Copy the folder

Take nwave-ai/nw-diagram from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
