What problem does it solve? Non-TDD work like Terraform changes, Nix configuration, CI pipelines, and documentation lacks a Red-Green test gate, so it is easy to execute ad hoc without verifiable completion criteria. This Skill produces a structured plan file where every work item carries a concrete verification step and expected outcome. ## Core Features & Use Cases - Verify-Required Planning: Every work item includes a Verify step with a command and concrete expected outcome, replacing TDD's test gate for non-application work. - Apply-Tier Safety: Live-state mutations (terraform apply, nix switch, kubectl apply) are marked as apply items, gated behind validation steps, and carry explicit Rollback instructions. - Portable Plan Files: Plans are written to .plans/ as self-contained Markdown that a fresh executor, agent, or human can run with zero session context. - Use Case: You need to migrate Terraform state to an S3 backend. The Skill analyzes the repository, identifies check commands like terraform plan, and writes .plans/s3-state-backend.md with ordered, verifiable tasks ready for execution. ## Quick Start Ask the agent to create a work plan for your infrastructure or configuration change, for example: plan the migration of our CI release pipeline to a new workflow.
