Terraform Module Maintainer

A schema-driven workflow for creating, changing, and upgrading reusable Terraform modules for any provider.

Dev & CodingAdvanced★ 356⑂ 56AI score 9/10Last updated: Nov 1, 2026

What it does

  • Organizes Terraform module work into four modes: full create/restructure, targeted change (feature, bug, review finding), resolve review feedback with draft replies, and provider major upgrade.
  • MCP-first schema rule: never author provider arguments from memory — it calls Terraform MCP tools (get_latest_provider_version, get_provider_details) first, falling back to Registry docs via WebFetch.
  • Coverage ledger: every provider field must map to an exposed input, an output, a sensitive omission, a documented intentional omission, or "not applicable" — so "supports all features" is actually verifiable.
  • Trust-aware verification contract (Rule 3): in an untrusted workspace only safe checks (terraform fmt -check, terraform validate) run; pre-commit hooks, Makefile targets and generators are reported as skipped with a reason rather than silently passed.
  • Static config (.editorconfig, release config, GitHub Actions workflows) is copied from profile templates instead of regenerated.

Who it's for

  • Platform/infrastructure engineers who build and maintain shared Terraform modules in the terraform-aws-modules style.
  • Teams maintaining modules across AWS, GCP and Azure that need one consistent convention set.
  • Module maintainers who must triage review findings and bot comments and draft one reply per item.

Examples

  1. "Create a new AWS WAFv2 module" → schema lookup → coverage matrix → main.tf/variables.tf/outputs.tf plus examples/basic and examples/complete with a create = false disabled module call.
  2. "Fix only the missing nested block flagged in review" → targeted change mode: impact analysis, minimal edit, backwards-compatibility classification, change report / PR body.
  3. "Bump the AWS provider from 5.x to 6.x" → schema diff across versions → handle renamed/removed/split fields → raise the version constraint → write consumer migration notes.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/modulestf/modulestf/HEAD/.agents/skills/terraform-module-maintainer/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the .agents/skills/terraform-module-maintainer folder from the GitHub repo modulestf/modulestf into my ~/.claude/skills/terraform-module-maintainer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/modulestf/modulestf.git /tmp/modulestf && mkdir -p ~/.claude/skills && cp -r /tmp/modulestf/.agents/skills/terraform-module-maintainer ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and move to a scratch directory.
  2. Clone the repository: git clone https://github.com/modulestf/modulestf.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the whole skill folder (the references/ and profiles/ subfolders are required): cp -r modulestf/.agents/skills/terraform-module-maintainer ~/.claude/skills/
  5. The skill references ../change-scope/SKILL.md, so copy the change-scope skill from the same repo as well.
  6. Restart Claude Code and try a request like "create a Terraform module for ..." to confirm it loads.
  7. For full value, install the Terraform MCP server, the terraform CLI, and — for trusted runs — pre-commit and terraform-docs.
