setup

A command for setting up Terraform development tools, including Terraform itself, its language server, format and lint checks, security scanners, documentation generators, cost estimates, and Terragrunt.

In plain words
What is it for?
Use it to verify or install the Terraform toolchain, configure terraform-ls for editor support, and prepare checks for style, security, documentation, and infrastructure cost.
Why use it?
It gathers the tools expected by the project’s hooks and helps check that the Terraform editing and validation environment is ready.

Command

Part of the terraform-lsp plugin — 2 commands shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/zircote/terraform-lsp/setup
Clone the repo
git clone --depth 1 https://github.com/zircote/terraform-lsp

Or install terraform-lsp, the plugin that ships this one along with the rest of its 2 commands.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 2,054 The whole file, excluding the scripts and references it only reads on demand.
Security scan D 3 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 D, and why

setup scanned grade D with 3 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 2d 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.

Asks for rootmediumPrivilege escalation

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

Instructions

Execute the following setup steps in order:

1. Verify Terraform Installation

Check that Terraform is installed:

terraform --version

If not installed, guide the user to https://developer.hashicorp.com/terraform/install or use:

# macOS (Homebrew)
brew tap hashicorp/tap
brew install hashicorp/tap/terraform

# Linux (apt)
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform

2. Install terraform-ls (Language Server)

Check if terraform-ls is available:

which terraform-ls || echo "terraform-ls not found"

Install terraform-ls:

# macOS (Homebrew)
brew install hashicorp/tap/terraform-ls

# Linux - download from releases
# https://github.com/hashicorp/terraform-ls/releases

# Or via go install
go install github.com/hashicorp/terraform-ls@latest

3. Install Required Linting Tools

Install TFLint for configuration linting:

# macOS (Homebrew)
brew install tflint

# Linux
curl -s https://raw.githubusercontent.com/terraform-linters/tflint/master/install_linux.sh | bash

# Initialize TFLint plugins
tflint --init

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.

setup is a command published in the GitHub repository zircote/terraform-lsp (2 stars, last pushed 23d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,054 tokens. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
