What problem does it solve? Platform engineering leaders struggle to turn business intent into a coherent Internal Developer Platform (IDP) strategy: deciding which capabilities to build versus buy, designing golden paths, structuring platform teams, measuring developer outcomes, and recording architecture decisions. This Skill provides the distinguished-architect playbook for those decisions while delegating all implementation to concrete infrastructure skills. ## Core Features & Use Cases - Strategy & Reference Architecture: Applies platform-as-a-product thinking, build-vs-buy decision trees, Wardley mapping, technology radar governance, and the five IDP planes (Developer Control, Integration & Delivery, Monitoring & Logging, Security, Resource) with capability-to-implementer delegation. - Org Design, Metrics & Governance: Designs Team Topologies interaction modes, DORA + SPACE + adoption scorecards, MADR-style ADR/RFC processes, and CNCF maturity model assessments with sequenced roadmaps. - Read-Only Assessment Scripts: Ships three bash tools — dora-metrics-report.sh (DORA proxies from git history), adr-lint.sh (MADR structure linting), and platform-maturity-scan.sh (IDP maturity signal detection). - Use Case: A principal architect asked to "define our platform strategy" uses this Skill to produce an investment thesis, a golden-path spec, a Team Topologies interaction map, a DORA baseline scorecard, and a CNCF maturity assessment — then hands Terraform, Crossplane, and GitOps implementation to sibling skills. ## Quick Start Use the platform-architect skill to assess our platform maturity and draft a golden-path spec for shipping a stateless HTTP service.
