Build Safer Terraform and OpenTofu Workflows

Terraform changes can expose secrets, replace resources, or corrupt shared state. This skill diagnoses those risks and provides version-aware implementation and validation guidance.

Supports: Claude Codex Code(CC)

⚠️ 38 Poor

Do not auto-install this skill.

The canonical policy requires operator review before any installation action.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request

Review the Skillstore skill "terraform-skill" from https://skillstore.io/skills/antonbabenko-terraform-skill.md and its manifest at https://skillstore.io/api/skills/antonbabenko-terraform-skill/manifest. Verify the artifact. Do not auto-install. Inspect the skill and report your findings, then wait for an operator or manual installation decision.

Your Agent should still show its plan and request any confirmation required by the security policy.

Agent-readable resources

Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.

Test it

Using "terraform-skill". A module changed from count to for_each and the plan replaces production instances.

Expected outcome:

Risk: resource identity churn can cause unintended replacement.
Recommendation: map old addresses to stable keys with migration blocks.
Validation: review a saved plan and confirm zero unexpected destroys before approval.

Using "terraform-skill". A team wants Terraform to read a database password from a standard variable.

Expected outcome:

Risk: sensitive variables remain in Terraform state even when display is masked.
Recommendation: use supported write-only or ephemeral mechanisms, or keep secret material outside Terraform.
Validation: inspect the plan and state handling without printing the secret.

Using "terraform-skill". A CI job plans again during apply after the pull request plan was approved.

Expected outcome:

Risk: the applied configuration can differ from the reviewed plan.
Recommendation: store the approved plan securely and apply that exact artifact.
Validation: require protected-environment approval and verify artifact provenance.

Security Audit

Critical

v1 • 8/13/2026 Open versioned report

The skill has defensive intent and requires reviewed plans, confirmation for destroy operations, and state-secret safeguards. Most static matches are Markdown syntax, Terraform identifiers, placeholders, or labeled examples rather than executable threats. Confirmed risks are an unverified pipe-to-shell installer, its mutable source URL, fragile xargs deletion, an unpinned action, and direct auto-approved apply examples.

Confirmed security concerns (3)

Critical

references/security-compliance.md:43

Pipe to shell pattern

curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b

The installation example pipes a mutable remote script directly into sh without checksum or signature verification. A compromised upstream response would gain immediate code execution.

High

references/security-compliance.md:46

Unpinned GitHub Action

The Trivy CI example uses aquasecurity/trivy-action@master. A mutable branch reference can change without review and execute compromised action code with workflow permissions.

The source directly uses the mutable master ref, while another reference file demonstrates a pinned Trivy action version.

High

references/state-management.md:583 references/state-management.md:606 references/state-management.md:615

Direct Auto-Approved Infrastructure Apply

State-locking examples run terraform apply -auto-approve without applying a reviewed saved plan. Reusing this guidance can bypass change review and mutate infrastructure unexpectedly.

Three operational examples invoke direct auto-approved applies, contrary to the core requirement to apply a reviewed plan artifact.

Capability review items (2)

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

High

references/security-compliance.md:43

Hardcoded URL

curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b

This URL supplies the script executed by the pipe-to-shell command on the same line. It references a mutable branch path and provides no integrity verification.

Medium

references/state-management.md:1184

xargs command (can execute arbitrary commands)

ls -t $BACKUP_DIR/terraform.tfstate.* | tail -n +31 | xargs rm -f

The backup cleanup pipes parsed ls output into xargs rm and leaves BACKUP_DIR unquoted. Spaces or crafted filenames can split arguments and remove unintended files.

What You Can Build

Refactor a Shared Module

Plan address-preserving changes, add migration blocks, and validate that production resources are not replaced.

Build a Controlled Delivery Pipeline

Create validation, testing, policy, plan, approval, and exact-plan apply stages for infrastructure changes.

Recover and Harden Remote State

Investigate locks or drift, select a recovery path, and document backup and rollback evidence.

Try These Prompts

Review a Terraform Configuration

Review this Terraform configuration for correctness and safety. State runtime assumptions, identify risks, propose focused changes, and provide validation steps.

Design a Reusable Module

Design a reusable [provider] module for [service]. Target [Terraform or OpenTofu version]. Include typed inputs, stable outputs, tests, security controls, and usage guidance.

Create an Infrastructure Pipeline

Design a CI/CD workflow for this repository. Separate validation, testing, security, plan, approval, and apply stages. Apply only the reviewed plan artifact.

Plan a State Recovery

Diagnose this [lock, drift, migration, or corruption] incident. Use the supplied backend details and logs to create evidence-preserving recovery and rollback procedures.

Best Practices

Provide the runtime, exact version, providers, backend, execution path, and environment criticality.
Review saved plans and retain rollback evidence before destructive or state-mutating operations.
Pin runtimes, providers, modules, actions, and lockfiles according to the environment risk.

Avoid

Do not apply directly to production without a reviewed plan artifact and approval.
Do not assume sensitive variables keep secret values out of state.
Do not rename resource addresses blindly or use list indexes as durable identity.
