manage-sprite-atlas — Claude Code skill for Unity atlases
This skill guides SpriteAtlas creation and setup in Unity projects through the build pipeline. Use it when configuring built-in atlases or Addressables loading.
npx skills add Unity-Technologies/skills --skill manage-sprite-atlas -a claude-codeWhat manage-sprite-atlas does
The skill guides SpriteAtlas work in Unity: it asks you to choose a delivery method, check for scripts already in the project, and configure Sprite Packer. Its default path generates atlases during the prebuild pipeline; manual authoring is reserved for cases where the user explicitly requests it.
Before code is written, the skill requires checking packing settings and reading relevant files from resources/. It keeps editor authoring separate from runtime atlas access. When EditorSettings.spritePackerMode is Disabled, the atlas will not pack, even if it appears ready in the editor.
On-demand loading through Addressables requires the Addressables package, a content build step, and a runtime loader script. This route also uses asynchronous loading and depends on a network connection. The skill asks you to choose between atlases included in the build for immediate access and Addressables loading on demand.
What it helps with
- generate SpriteAtlas assets during a Unity build
- set up on-demand atlas loading with Addressables
- check whether Sprite Packer is enabled
- decide how existing atlas scripts should be handled
Example prompts for the agent
- Set up Unity sprite atlases for the main UI and generate them during the build.
- Prepare Addressables loading for atlases used by downloadable content.
- Check for existing SpriteAtlas scripts and verify the packing mode before generating code.

What does manage-sprite-atlas do?
It guides SpriteAtlas setup in Unity, including build-time generation and Addressables loading. It checks for existing scripts and packing settings before generating code.
What is needed to load atlases through Addressables?
The project needs the Addressables package, an Addressables content build step, and a runtime loader script. This option uses asynchronous loading and has a network dependency.
