Use when generating, reviewing, refactoring, or migrating IaC and when building delivery/testing pipelines." --- # Terrashark: Failure-Mode Workflow for Terraform/OpenTofu Run this workflow top to bottom. ## 1) Capture execution context Record before writing code: - runtime (`terraform` or `tofu`) and exact version - provider(s), target platform, and state backend - execution path (local CLI, CI, HCP Terraform/TFE, Atlantis) - environment criticality (dev/shared/prod) If unknown, state assumptions explicitly. ## 2) Diagnose likely failure mode(s) Select one or more based on user intent and risk: - identity churn: resource addressing instability, refactor breakage - secret exposure: secrets in state, logs, defaults, artifacts - blast radius: oversized stacks, weak boundaries, unsafe applies - CI drift: version mismatch, unreviewed applies, missing artifacts - compliance gate gaps: missing policies/approvals/audit controls ## 3) Load only the relevant reference file(s) Primary references: - `references/identity-churn.md` - `references/secret-exposure.md` - `references/blast-radius.md` - `references/ci-drift.md` - `references/compliance-gates.md` Supplemental references (only when needed): - `references/testing-matrix.md` - `references/quick-ops.md` - `references/examples-good.md` - `references/examples-bad.md` - `references/examples-neutral.md` - `references/coding-standards.md` - `references/module-architecture.md` - `references/ci-delivery-patterns.md` - `references/security-and-governance.md` - `references/do-dont-patterns.md` - `references/mcp-integration.md` Conditional references (CRR; load only on detected signals): - `references/conditional/backend-state-safety.md` (backend is `s3`, `azurerm`, `gcs`, `remote`, `cloud`, `pg`, `consul`, or `local`, or task mentions backend migration, locking, state backup, or restore) - `references/conditional/trusted-modules.md` (provider is `aws`, `azurerm`, `google`, `oci`, or `ibm`) Do not load multiple conditional references unless the task spans multiple detected backends, providers, or tools. ## 4) Propose fix path with explicit risk controls For each fix, include: - why this addresses the failure mode - what could still go wrong - guardrails (tests, approvals, rollback) ## 5) Generate implementation artifacts When applicable, output: - HCL changes (typed vars, stable keys, bounded versions) - migration blocks (`moved`, import strategy) - CI pipeline updates (plan/apply separation, artifacts, policy checks) - compliance controls (approvals, policy rules, evidence paths) When a trusted registry module covers the requested resource and the user has not asked for raw HCL, default to that module with an exact `version` pin (see `references/conditional/trusted-modules.md`). ## 6) Validate before finalize Always provide command sequence tailored to runtime and risk tier. Never recommend direct production apply without reviewed plan and approval. ## 7) Output contract Return: - assumptions and version floor - selected failure mode(s) - chosen remediation and tradeoffs - validation/test plan - rollback/recovery notes for destructive-impact changes

Install the "Terrashark" agent skill from https://github.com/LukasNiessen/terrashark/blob/main/SKILL.md. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Terraform Skill for Claude Code and Codex. LLMs hallucinate a lot with Terraform - TerraShark fixes this. It eliminates hallucinations, is designed for modular and secure code and grounds your IaC in the official Hashicorp Terraform best practices.

Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: SKILL.md.
