Enforce production-proven cloud infrastructure standards — multi-account governance, Terraform organization, naming conventions, zero-static credentials, CI/CD pipelines, and operational hygiene — with automated audits and remediation guidance for AWS, GCP, and Azure
npx claudepluginhub oborchers/fractional-cto --plugin cloud-foundation-principlesThis skill should be used when the user is making significant infrastructure decisions, documenting architectural choices, creating decision records, tracking exemptions from IaC, establishing decision-making processes, or onboarding new team members to existing infrastructure. Covers ADR format, numbering, status lifecycle, exemption tracking, and decision governance.
This skill should be used when the user is building Docker images, configuring container registries, designing image tagging strategies, setting up registry lifecycle policies, debugging production incidents that require tracing running code, or discussing OCI labels and build metadata. Covers git SHA tagging, the traceability chain from container to source code, registry retention policies, OCI build labels, and why date-based or environment-based tags fail.
This skill should be used when the user is choosing between managed and self-hosted services, deciding whether to run Kubernetes or use managed containers, evaluating self-hosted databases vs managed databases, considering self-hosted monitoring or caches, designing for a small team (under 50 engineers), or justifying a self-hosted exception. Covers the operations tax of self-hosting, managed container orchestration over Kubernetes for small teams, managed workflow engines, managed caches and databases, managed monitoring, and the decision framework for when self-hosting is genuinely justified.
This skill should be used when the user is setting up a new cloud project, designing account or project structure, creating environment isolation, configuring organization units or management groups, implementing landing zones, or deciding how to separate dev and prod workloads. Covers multi-account strategy, blast radius isolation, landing zone setup, and organizational governance.
This skill should be used when the user is designing resource naming conventions, implementing tagging or labeling strategies, building a labels module, setting up cost center attribution, creating naming standards for cloud resources, or reviewing tag compliance. Covers naming patterns, labels modules, cost center validation, tag enforcement, and naming across resource types.

Generic AI gives you suggestions. fractional-cto gives you standards.
Each skill encodes a proven engineering principle (naming precision, API design patterns, cloud governance) and enforces it the moment Claude detects relevant work. You get the rigor of Stripe's API design, Nielsen Norman's usability research, and production cloud architecture baked into every session. No bookshelf required.
The skills are deliberately opinionated. They don't present five options and ask you to choose. They tell you what to do, cite why, and show you the code. If you disagree, edit the skill. It's just markdown.
Every plugin activates the moment your Claude session starts. A session hook fires, reads the plugin's skill index, and injects it into context. From that point on, Claude knows what principles exist and when to apply them.

Each plugin carries review checklists, good/bad pattern comparisons, working code examples, and a dedicated reviewer agent for deeper audits.
