About this skill
Ark Controller Development
Guidance for developing the Ark Kubernetes operator in ark/.
When to use this skill
- Modifying Go type definitions (
api/v1alpha1/*_types.go) - Fixing CRD/Helm chart sync errors
- Adding new CRD fields or resources
CRD Generation Flow
api/v1alpha1/*_types.go # Go types with markers
↓
make manifests # Generates CRDs and syncs to Helm chart
↓
config/crd/bases/*.yaml # Source CRDs (auto-generated)
dist/chart/templates/crd/ # Helm chart CRDs (auto-synced)
make manifests automatically syncs source CRDs to the Helm chart while preserving templated headers.
Fixing "CRDs out of sync" Errors
When make build fails with CRD validation errors:
cd ark
make manifests
make build
Key Directories
| Directory | Purpose |
|---|---|
api/v1alpha1/ | Go type definitions |
config/crd/bases/ | Auto-generated source CRDs |
dist/chart/templates/crd/ | Helm chart CRDs (auto-synced) |
internal/controller/ | Reconciliation logic |
internal/webhook/ | Admission webhooks |
internal/genai/ | AI/ML execution logic |
Common Tasks
After Modifying Types or Comments
Go type comments become CRD field descriptions:
cd ark
make manifests
make build
After Any Go Code Change
make lint-fix # Format and fix linting
make build # Build and validate

This skill should be used when working on Godot Engine projects. It provides specialized knowledge of Godot's file formats (.gd, .tscn, .tres), architecture patterns (component-based, signal-driven, resource-based), common pitfalls, validation tools, code templates, and CLI workflows. The `godot` command is available for running the game, validating scripts, importing resources, and exporting builds. Use this skill for tasks involving Godot game development, debugging scene/resource files, implementing game systems, or creating new Godot components.

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
