description: Use this skill for any task that creates, modifies, inspects, or destroys cloud infrastructure or SaaS configuration, from one-off CLI operations to full multi-resource projects, across providers in the Pulumi ecosystem. A typical project spans many providers (AWS or Azure or GCP, Kubernetes, Cloudflare, Auth0, Datadog, Vercel, and others), and Pulumi drives them through one CLI, one state model, and one credential layer. Trigger even when the user does not name Pulumi; phrasings like "deploy this app," "provision a database," "stand up a VPC," "configure Auth0," "set up Datadog monitoring," or "tear down staging" qualify. Also trigger for tasks that migrate, port, or convert existing infrastructure code (Terraform, CloudFormation, CDK, Bicep, ARM) to Pulumi. Do not trigger for application runtime code that reads or writes data via cloud SDKs; that is application code, not infrastructure.

# Pulumi
Pulumi is a tool for creating and managing cloud infrastructure: virtual machines, storage, Kubernetes clusters, databases, anything from any provider. You write code or run CLI commands, Pulumi previews what would change, then applies it. This skill walks three levels of working with Pulumi, from a single CLI command up to a project with policies and scheduled drift. Start at the smallest level that fits the task.
## The three levels
Level 1 is `pulumi do`, a CLI for direct CRUD against any provider, with no project files or programming language. Level 2 is a Pulumi project in Python, TypeScript, Go, C#, or Java, used once the work involves multiple related resources, loops or conditionals, reusable abstractions, or environment-specific variants. Level 3 layers Pulumi Cloud onto a project for ESC credentials and configuration, policy, hosted execution, drift detection, schedules, and audit.
| Level | Surface | When to use |
|-------|---------|-------------|
| 1 | `pulumi do` | Single resource or multi-vendor bootstrapping |
| 2 | Pulumi project (Python, TS, Go, C#, Java) | Multiple resources, abstractions, environments |
| 3 | ESC, policy, deployments, drift, schedules | Governance, secrets, scheduled and hosted runs |
When the directory has no existing Pulumi project, a user asking to create a single bucket is a Level 1 task; do not scaffold a new project for it. A request to provision a VPC with subnets and a Kubernetes cluster is Level 2 from the start. A request for nightly drift detection on an existing stack is Level 3.
Converting existing infrastructure code from another tool (Terraform, CloudFormation, CDK, ARM, or Bicep) is a separate path: route straight to the migration skills listed in the table at the end, independent of the level model.
Picking the right level requires knowing what is already in the directory. If you can inspect the filesystem, do so. If you cannot (restricted agent contexts), ask the user before any Pulumi command runs whether there is an existing Pulumi project in the directory. Don't run a Pulumi command to find out: commands that would otherwise require a login silently provision a new agent account, parallel to one the user may already own.
