azure-diagrams-skill: Instructions file for Codex

AGENTS.md

azure-diagrams-skill AGENTS.md is an instructions file for Codex, OpenCode from cmb211087/azure-diagrams-skill. It costs 699 tokens per session, scanned B, original, MIT.

Instructions for generating Azure architecture diagrams and other technical diagrams as code. Azure is Microsoft’s cloud platform; the instructions use Python, Graphviz, and the diagrams library to create visuals from code or infrastructure templates.

In plain words
What is it for?
Use them to create Azure service diagrams, business-process flows, entity-relationship diagrams, timelines, wireframes, sequence diagrams, and network topologies.
Why use it?
They define the required tools and conventions for producing repeatable diagrams instead of drawing each one manually. They also explain how to represent systems described in Bicep, Terraform, or ARM files.

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 B, and why

azure-diagrams-skill AGENTS.md scanned grade B with 1 finding 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 11d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

AGENTS.md - Azure Architecture Diagrams

This repository is an agent skill for generating professional technical diagrams as code. It works with any AI coding tool (Claude Code, GitHub Copilot, Cursor, Windsurf, and any tool that reads AGENTS.md or Agent Skills). The full instructions live in skills/azure-diagrams/SKILL.md; this file is the portable summary for tools that do not load SKILL.md automatically.

What it does

Generates Azure architecture diagrams (800+ Azure service icons), plus business-process flows, ERDs, timelines/Gantt, UI wireframes, sequence diagrams and network topology, using the Python diagrams library and Graphviz. It can also build diagrams from Bicep, Terraform and ARM templates.

Prerequisites (cross-platform)

  1. Graphviz (system package, provides the dot engine), then restart the terminal:
    • Windows: winget install -e --id Graphviz.Graphviz (or choco install graphviz)
    • macOS: brew install graphviz
    • Linux: sudo apt-get install graphviz
  2. Python 3.9+ with the library: pip install "diagrams>=0.25.1"

See SETUP.md for a full, step-by-step setup with troubleshooting.

How to generate a diagram

Write the image to a diagrams/ folder in the working directory (portable everywhere); do not leave a throwaway .py script behind.

macOS / Linux (and Claude Code, Cursor):

mkdir -p diagrams
python3 << 'EOF'
from diagrams import Diagram
from diagrams.azure.compute import AKS
from diagrams.azure.database import CosmosDb
with Diagram("My Architecture", filename="diagrams/architecture", show=False, outformat="png"):
    AKS("aks-prod") >> CosmosDb("cosmos-prod")
EOF

Windows (PowerShell, e.g. GitHub Copilot):

New-Item -ItemType Directory -Force diagrams > $null
@'
from diagrams import Diagram
from diagrams.azure.compute import AKS
from diagrams.azure.database import CosmosDb
with Diagram("My Architecture", filename="diagrams/architecture", show=False, outformat="png"):
    AKS("aks-prod") >> CosmosDb("cosmos-prod")

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.
