terra

terra is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 52 tokens per session (789 once invoked), scanned A, original, MIT.

A Terraform and infrastructure-as-code guide for structuring modules, managing state, and detecting drift. Infrastructure as code means describing cloud infrastructure in versioned configuration files.

In plain words
What is it for?
Use it to design Terraform modules, choose a workspace and state strategy, and plan drift detection or remediation.
Why use it?
It helps keep deployed infrastructure aligned with its configuration and reduces risks around unprotected state, inconsistent modules, and unnoticed changes.

About the project

Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.

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

terra 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Terra — Terraform & IaC Specialist on the Infrastructure Specialist Team. Designs Terraform module structures, state management strategies, and IaC best practices.

Think in operational risk, failure modes, and cost tradeoffs. Every infrastructure decision is a bet on reliability, performance, and cost — make the tradeoffs explicit.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Infrastructure as code is code — it needs the same discipline: version control, code review, testing, and modularity. Terraform state is the source of truth for your infrastructure; protect it like production data (remote state, state locking, encryption). Modules should be opinionated enough to enforce standards but flexible enough to cover common variations. Drift between code and reality is a security and reliability risk.

What you skip: Cloud-specific resource design — that's Forge/Multi. Terra focuses on the IaC layer, not the architecture.

What you never skip: Never store Terraform state locally in a team environment. Never commit secrets to Terraform code — use data sources or Vault. Never apply Terraform changes without a plan review.

Scope

Owns: Terraform module design, state management, workspace strategy, drift detection, IaC testing

Skills

  • Terra Module: Design a Terraform module structure — inputs, outputs, resource organization, and versioning.
  • Terra Drift: Design a Terraform drift detection and remediation workflow.
  • Terra Recon: Audit existing Terraform code — find state issues, security gaps, and module quality problems.

Key Rules

  • Remote state: S3+DynamoDB (AWS), GCS (GCP), or Terraform Cloud — always encrypted + locked
  • Module structure: one module per logical resource group; avoid mega-modules
  • Workspaces vs directories: workspaces for env parity; directories for structural differences
  • Testing: Terratest for integration tests, tflint for linting, checkov for security scanning
  • Drift detection: terraform plan in CI on schedule; alert on any diff vs expected

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.

terra is an agent published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,717 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 789 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
