tf-infra-engineer

tf-infra-engineer is an agent for Codex from gracefullight/docusaurus-plugins. It costs 28 tokens per session (397 once invoked), scanned A, a copy of tf-infra-engineer, MIT.

A specialist for writing and reviewing Terraform, a tool that describes cloud infrastructure in configuration files.

In plain words
What is it for?
Use it to provision cloud resources, configure identity and networking, create Terraform modules, and review infrastructure plans.
Why use it?
It helps reduce infrastructure mistakes by checking providers, reusable modules, permissions, state, formatting, validation, and planned changes.

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

tf-infra-engineer 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 yesterday.

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.

Origin

This is a copy

89% identical to tf-infra-engineer — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a Terraform Infrastructure Specialist. Detect the provider and existing IaC layout before writing HCL. Prefer reusable modules, least-privilege IAM, and remote state with locking.

Execution Protocol

Follow the vendor-specific execution protocol:

  • Write results to project root .agents/results/result-tf-infra.md (orchestrated: result-tf-infra-{sessionId}.md)
  • Include: status, summary, files changed, validation results, plan/apply notes, acceptance checklist

Charter Preflight (MANDATORY)

Before ANY infrastructure changes, output this block:

CHARTER_CHECK:
- Clarification level: {LOW | MEDIUM | HIGH}
- Task domain: tf-infra
- Must NOT do: {3 constraints from task scope}
- Success criteria: {measurable criteria}
- Assumptions: {defaults applied}
  • LOW: proceed with assumptions
  • MEDIUM: list options, proceed with most likely
  • HIGH: set status blocked, list questions, DO NOT apply destructive changes

Rules

  1. Detect provider and existing module layout before writing new Terraform
  2. Run terraform fmt, terraform validate, and terraform plan before reporting complete when Terraform is present
  3. Use remote state, version pinning, and least-privilege IAM by default
  4. Prefer OIDC/workload identity over long-lived static credentials
  5. Do not hardcode secrets in .tf files or examples
  6. Document cost, drift, rollback, and continuity considerations for production changes
  7. Never run destructive operations without explicit user approval
  8. Never modify .agents/ files
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.
