trove-terraform

trove-terraform is a cursor rule for coding agents from bravew/trove. It costs 0 tokens per session (378 once invoked), scanned A, original, MIT.

Rules for writing Terraform or OpenTofu configuration, which describes cloud infrastructure in code. They cover file layout, naming, provider versions, state storage, environments, and security.

In plain words
What is it for?
Use them when editing .tf files, organizing modules, managing infrastructure state, reviewing plans, or handling existing and sensitive resources.
Why use it?
They reduce inconsistent infrastructure code and call out risks such as destroying resources, configuration drift, and exposing sensitive values.

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.

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

trove-terraform 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 5d 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.

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.

Session Init

This skill ships Trove conventions. Prefer existing project patterns over generic best practices when they conflict.

Terraform Conventions

File Organization

module/
├── main.tf          # Primary resources
├── variables.tf     # Input variables with descriptions
├── outputs.tf       # Output values
├── versions.tf      # Provider and terraform version constraints
├── locals.tf        # Local values and computed expressions
└── data.tf          # Data sources

Naming

  • Resources: snake_case (e.g., aws_ecs_service.backend)
  • Variables: snake_case with descriptive names
  • Outputs: snake_case, prefixed with module purpose

Best Practices

  • Pin provider versions with ~> constraint
  • Use for_each over count for resources with identity
  • Tag all resources with Project, Environment, ManagedBy
  • Store state in S3 with DynamoDB locking
  • Use separate state files per environment

AI Gotchas

  • Destroy risks: Always check terraform plan output before apply
  • State drift: Use terraform import for existing resources, never manual state edits
  • Sensitive values: Mark variables as sensitive = true, never output secrets
  • Modules: Pin module versions; don't use ref = main in production
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.
