terraform-ops

terraform-ops is a skill for Claude Code from 0xDarkMatter/claude-mods. It costs 90 tokens per session (4,104 once invoked), scanned A, original, MIT.

A guide to managing cloud and other infrastructure with Terraform or OpenTofu, tools that describe servers and services in configuration files. It covers reusable modules, stored infrastructure state, secrets, planning, and safe changes.

In plain words
What is it for?
Use it to organize infrastructure projects, manage remote state, create modules, review plans, configure CI/CD, and handle secrets safely.
Why use it?
It helps prevent accidental infrastructure changes and confusion around shared state, modules, credentials, and deployment pipelines.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is │ │ ├── main.tf # module "network" { source = "../../modules/network" ... }.

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 A, and why

terraform-ops scanned grade A with 0 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 23d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check-action-refs.sh, tests/run.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Terraform Operations

Terraform / OpenTofu infrastructure-as-code: layout, state, modules, safety, CI/CD, secrets.

Version context (verified 2026-06): Terraform 1.15.x (BUSL-1.1 licence since 1.6) · OpenTofu 1.12.x (MPL-2.0 fork of Terraform 1.5.x). Commands below are interchangeable (terraform ↔ tofu) unless flagged. See Terraform vs OpenTofu for the decision note.

Reference Files

File Covers
references/state-management.md Remote backends, locking, moved/import/removed blocks, state surgery, drift detection
references/module-patterns.md Module composition, variable validation, optional/nullable, output contracts, versioning
references/cicd-pipelines.md GitHub Actions plan/apply, OIDC auth, policy gates (tflint/trivy/checkov/OPA), Atlantis/HCP
references/security-and-secrets.md Secrets in state, ephemeral resources, write-only arguments, SOPS/Vault, sensitive limits
assets/github-actions-terraform.yml Ready-to-adapt PR-plan + OIDC-apply workflow
scripts/check-action-refs.sh Staleness verifier for any workflow's uses: action refs (offline structural / live API resolve)

The action versions pinned in github-actions-terraform.yml are point-in-time (verified 2026-06). Run scripts/check-action-refs.sh --live before adopting — a tag that was valid at write time may have been retracted or never existed (e.g. [email protected] vs the real v0.33.1).

Project Layout Decision Tree

How many environments / accounts?
│
├─ One environment, one team
│  └─ Single root module + tfvars. Don't over-engineer.
│
├─ Multiple environments (dev/staging/prod)
│  ├─ Need different backend/account/region per env? (usually YES for prod isolation)
│  │  └─ DIRECTORY PER ENVIRONMENT (recommended default)
│  │     environments/{dev,staging,prod}/ each a thin root calling shared modules
│  │
│  └─ Environments truly identical except a few variables, same backend account?
│     └─ Workspaces are *acceptable* — but see the workspace caveats below
│
└─ Many teams / many state files / platform engineering
   └─ Directory-per-env + per-component state split (network / data / app)
      Consider Terragrunt, Terraform Stacks (HCP), or OpenTofu + CI orchestration

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
