Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00111 | $0.01230 |
| Opus 5 | $0.00056 | $0.00615 |
| Sonnet 5 | $0.00022 | $0.00246 |
| Haiku 4.5 | $0.00011 | $0.00123 |
Grade A, and why
browse-templates scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
88% identical to browse-templates — 32 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/browse-templates — Pick a community template and clone it
onyx's community templates live in github.com/OnyxEngine 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 Onyx 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
onyx: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
onyx 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/OnyxEngine.
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-controllerlooks right. Want me to clone it asmy-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 this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Other skills, from other repositories
make-game
Use when the user says "make me a game", "build me a game", "I want to make a [genre] game", "let's build something" — the orchestration spine that runs the full game-dev pipeline: brainstorm → plan → scaffold → build core mechanics → art direction → audio → polish/VFX → verify → ship. Delegates to specialist skills…
brainstorm-game
Use when the user wants help deciding what game to make, scoping a new project, or turning a vague idea into a buildable plan. Walks through genre, scope, core loop, mechanics, and art direction, then writes a 1-page brief to .summer/GameSoul.md. Trigger on "brainstorm a game", "what should I make", "I want to make a…
scene-composition
Use when building or organizing Summer Engine scenes: node hierarchy conventions, when to extract sub-scenes, reusable prefab patterns, and instance-versus-add-node decisions. Trigger on "scene", "sub-scene", "instance", "prefab", "node hierarchy", "scene structure", "PackedScene".
browse-templates
Use when the user wants to see available Summer Engine project templates, start from an existing template, or asks "what templates exist?" — fetches the live list from github.com/SummerEngine, presents the choices, and creates a project from the chosen template via summer create . Trigger on "templates", "starter"…
new-project
Use when the user wants a fresh blank Summer Engine project — not from a template. Asks one question (project name) and runs summer create empty . Trigger on "new project", "blank project", "empty project", "from scratch", "start fresh", "create new game", "blank canvas", "scaffold a project".
play
Use when the user says "play", "run it", "test it", "let me see it", or "start the game". Runs the project in Summer Engine, briefly waits, then reports what's happening — clean run, errors, or warnings.
