apex-terraform-patternsUTILITY SKILL — Reusable Azure Terraform patterns: hub-spoke, private endpoints, diagnostics, AVM-TF modules.
Apex Terraform Patterns is an agent skill from jonathan-vella/apex. UTILITY SKILL — Reusable Azure Terraform patterns: hub-spoke, private endpoints, diagnostics, AVM-TF modules. WHEN: "hub-spoke Terraform", "private endpoint module", "AVM-TF composition", "diagnostic settings", "plan interpretation". DO NOT USE FOR: Bicep code (apex-azure-bicep-patterns), ADRs (apex-azure-adr), diagrams (apex-python-diagrams).
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including reference files (for example `references/avm-authoring-requirements.md`, `references/avm-pitfalls.md` and `references/avm-provider-compatibility.md`). Compatibility notes: Requires Terraform = 1.11, azurerm ~ 4.0, Azure CLI
It sits in DevOps & Cloud, covering Infrastructure as code and Architecture decision records. It works with Terraform, Bicep, Microsoft Azure and Python. The repository describes itself as: APEX turns Azure platform engineering requirements into verified, deploy-ready IaC — powered by GitHub Copilot agents, real-time pricing, and built-in compliance. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 15a629a. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
npmterraformFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires Terraform >= 1.11, azurerm ~> 4.0, Azure CLI
From compatibility in the SKILL.md frontmatter.
Apex Terraform Patterns loads about 2.2k tokens when it runs, and up to ~20k if it reads all its reference files. Until then it costs about 93 tokens; SKILL.md has 681 words of instructions outside code blocks.
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.
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.

hardcode IDs. AVM-TF module versions in APEX-generated code MUST be exact semver
(version = "X.Y.Z") — pinned at plan time from
registry.terraform.io (newest stable in modules[0].versions[]). Range
constraints (~> X.Y, >= X.Y.Z) are NOT allowed in 04-iac-contract.json and
will be flagged by npm run validate:avm-versions. Full code sample

Apex Terraform Patterns fits situations like: : Bicep code (apex-azure-bicep-patterns); ADRs (apex-azure-adr); diagrams (apex-python-diagrams).
Run `npx skills add jonathan-vella/apex --skill apex-terraform-patterns -a claude-code`. Or copy the skill folder (.github/skills/apex-terraform-patterns in jonathan-vella/apex) into .claude/skills/apex-terraform-patterns in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jonathan-vella/apex --skill apex-terraform-patterns -a codex`. Or copy the skill folder (.github/skills/apex-terraform-patterns in jonathan-vella/apex) into .agents/skills/apex-terraform-patterns in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jonathan-vella/apex --skill apex-terraform-patterns -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/apex-terraform-patterns, .gemini/skills/apex-terraform-patterns, .github/skills/apex-terraform-patterns and .opencode/skills/apex-terraform-patterns in your project.
Going by SKILL.md and its folder, Apex Terraform Patterns needs the command-line tools its instructions call (npm and terraform). Compatibility (from SKILL.md): Requires Terraform >= 1.11, azurerm ~> 4.0, Azure CLI.
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Apex Terraform Patterns is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 18k tokens, read only when the agent opens those files.
