Browse Templates

/browse-templates — Pick a community template and clone it

Summer's community templates live in github.com/SummerEngine under template-* repos: template-3d-third-person-controller, template-3d-lan-multiplayer-starter, template-2d-platformer, and so on. They're working starter projects — open in Summer Engine and play immediately.

When to use this skill

• User asks "what templates do you have?" / "what starter projects exist?"
• User says "start from a template" / "use the X template" / "is there a Y starter?"
• User describes a game shape that maps to a known template (third-person 3D, multiplayer, 2D platformer)
• User asks for a specific known template by name

When NOT to use this skill

• User says "blank project" / "empty project" / "from scratch" → use summer:new-project.
• User wants to make a new template (contribute one) → that's not this skill; point them at the README's contributing section.

Steps

1. Fetch the live list

summer list templates

That hits the GitHub org API and prints both built-in templates (offline-friendly) and community templates with descriptions. Always run this first — never recommend a template from memory. The list evolves; what you remember may be stale, archived, or renamed.

If the command errors out (rate-limit, offline), tell the user and offer the built-ins (empty, 3d-basic) plus the canonical URL: github.com/SummerEngine.

2. Help the user pick

If the user has a specific game shape in mind, narrow before showing all options:

> "Looking for a third-person 3D template — 3d-third-person-controller looks right. Want me to clone it as my-game?"

If they're undecided, show 3–5 options grouped by genre, with a one-line description each. Don't dump the full list. A long menu freezes decisions.

3. Confirm the project name

Default is the template slug (so 3d-third-person-controller → directory 3d-third-person-controller). Almost always wrong. Always ask:

> "What do you want to call your project? (default: 3d-third-person-controller)"

4. Clone

summer create  

Example:

summer create 3d-third-person-controller hero-game

This:

• Clones the latest main (or default branch) of template-3d-third-person-controller
• Drops the .git directory so the user starts with their own history
• Prints the source URL for transparency

Pass --keep-git if the user wants the upstream history (rare).

5. Open it in the engine

summer run 

Confirm it opens. Then invoke summer:play to verify the template runs as expected before doing any custom work on top.

Anti-patterns

| Don't | Why | |---|---| | Recommend a template from memory | List evolves. summer list templates is the source of truth. | | Dump the full template list as a wall of text | 5 curated picks beats 20 generic ones. Match to user intent. | | Default the project name to the slug | 3d-third-person-controller/ is a UX-hostile directory name. Always ask. | | Skip summer run after cloning | Templates can break upstream — verify the user has a working baseline before they edit. | | Clone into an existing directory | The CLI errors out; respect that and ask for a different name. |

Edge cases

• git not installed → summer create errors with a clear message. Tell the user to install git, or fall back to a built-in template.
• Template archived or moved → the API filter excludes archived repos. If a user names one explicitly that's gone, the create command lists what's currently available.
• Network down → fall back to empty or 3d-basic. Don't pretend the remote ones exist.

After the user is in

Once the project is created and running, hand off cleanly. The next skill that fires depends on the template:

• Third-person controller → likely summer:scene-composition or summer:gdscript-patterns next.
• Multiplayer starter → summer:setup-multiplayer or summer:host-authoritative-state.
• 2D platformer → summer:design-mechanic for the platforming feel, then summer:design-level.

Don't auto-fire the next skill — wait for the user to say what they want to change first.
