What Terraform Code Generation is

Terraform Code Generation is a plugin published in the hashicorp/agent-skills repository on GitHub, which has about 875 stars. The repository describes itself as: “A collection of Agent skills and Claude Code plugins for HashiCorp products.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Terraform Code Generation adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

How to install Terraform Code Generation

Claude Code

Add the repository as a plugin marketplace: claude plugin marketplace add hashicorp/agent-skills
Install the plugin: claude plugin install terraform-code-generation@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

Open Customize → Plugins and choose Add marketplace.
Enter hashicorp/agent-skills (the owner/repo shorthand works for GitHub).

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
