+# Agent Instructions
+
+Rules and gotchas for AI agents working on the `karpenter-operator` repository.
+
+## What This Repo Is
+
+`karpenter-operator` is an OpenShift operator that deploys and manages [Karpenter](https://karpenter.sh/) on OpenShift clusters. It discovers the cluster's cloud provider at runtime and configures Karpenter accordingly.
+
+## Multi-cloud Rules
+
+This operator must support multiple cloud providers. Only AWS is implemented so far, but these rules apply to all code changes:
+
+- **Never import cloud-provider SDKs in generic packages.** Cloud-specific code belongs in `pkg/cloudprovider/<provider>/`. Generic code in `cmd/`, `pkg/operator/`, and `pkg/controllers/` must interact through the `CloudProvider` interface only.
+- **Detect the provider at runtime** from the `Infrastructure` CR (`status.platformStatus.type`), not from build tags or hardcoded assumptions.
+- When adding provider-specific behavior, ask: "What would the other providers need here?" and leave room for it (interface methods, switch statements, TODOs).
+
+## Operator / Operand Separation
+
+The **operator** (this binary) manages the **operand** (Karpenter). They are separate images in separate Deployments. Do not conflate them — the operator creates and manages the operand's Deployment, ServiceAccount, and RBAC. They share a namespace but have independent credentials and RBAC.
+
+The operand image varies by cloud provider — each provider has its own Karpenter image. The operator must select the correct operand image based on the discovered infrastructure.
+
+## Coding Gotchas
+
+- **Dependencies are vendored.** Always run `make vendor` after changing `go.mod`. Do not use `go get` alone.
+- **Import ordering** is enforced by `.golangci.yml`. Run `make lint` after changes — it auto-fixes.
+- **Run `make verify`** after any code change. It runs vet, fmt, lint, and tests together.
+- **No narrating comments.** Do not add comments that restate what the code does. Comments should only explain non-obvious intent, trade-offs, or constraints.

+# karpenter-operator
+
+OpenShift operator that deploys and manages [Karpenter](https://karpenter.sh/) on Red Hat OpenShift clusters. Managed by the Cluster Version Operator (CVO) as part of the OpenShift release payload.
+
+## Building
+
+```bash
+make build        # Build the operator binary
+make test         # Run unit tests
+make lint         # Run golangci-lint
+make verify       # Run all checks (vet, fmt, lint, test)
+make docker-build # Build container image
+```
+
+## Deploying (dev)
+
+```bash
+make deploy \
+  IMG=quay.io/you/karpenter-operator:dev \
+  OPERAND_IMG=quay.io/you/karpenter:dev \
+  CLUSTER_NAME=my-cluster \
+  DEV=true
+```
