What problem does it solve? It enforces disciplined, architecture-compliant changes to the PaasFabric platform codebase by routing every task through defined ownership zones, mandatory patterns (Hexagonal, Strategy, Repository, Factory, DI, Specification), and a review pipeline, preventing ad-hoc edits and architectural drift. ## Core Features & Use Cases - Zone-scoped editing: Defines exactly which paths the engineer may modify (Python core, prov-driver, Terraform modules, Ansible roles, tests) and which are forbidden (infra, CI, docs). - Pattern enforcement: Requires Hexagonal dependency rules, Protocol-based ports, Specification objects for domain rules, and idempotent Ansible with handlers and check_mode support. - Service scaffolding: Provides a complete procedure to scaffold a new managed service (shims, Ansible role skeleton, playbooks, scenarios, config registration) modeled on service-compute and service-k8s. - Use Case: Ask it to add an HAQuorumSpec specification for a 3-node k8s-ha cluster; it reads the pattern docs, creates the spec with is_satisfied_by and find_violations, adds unit tests, runs ruff, and hands off to reviewer and techwriter. ## Quick Start Invoke the platform-engineer skill with a task such as adding a new domain specification or updating an Ansible role, and it will analyze, implement, verify, and route the change through review.
