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 | $0.00040 | $0.01985 |
| Opus 5 | $0.00020 | $0.00992 |
| Sonnet 5 | $0.00008 | $0.00397 |
| Haiku 4.5 | $0.00004 | $0.00198 |
Grade A, and why
start 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/start — Project Onboarding
Welcome the user and determine their starting point by asking:
"Where are you with this project?"
- No idea — I don't even have a game concept yet
- Vague concept — I have a rough idea but nothing documented
- Clear design — I have a GDD or design docs ready
- Existing code — I have a Roblox project with code already
Based on their answer:
If "No idea":
- Run
/brainstormto explore game ideas - Guide through genre selection, target audience, core loop definition
- Help define creative pillars (3-5 words each that describe the experience)
- Draft a 1-page game concept document
- Proceed to
/gddfor the master GDD
If "Vague concept":
- Ask them to describe their idea in 2-3 sentences
- Ask: What Roblox games inspire this? What's the core loop?
- Help crystallize: genre, setting, core mechanic, target audience
- Define creative pillars
- Proceed to
/gdd
If "Clear design":
- Ask them to share or describe their existing design docs
- Review for completeness against GDD standards
- Run
/project-stage-detectto assess readiness - Identify gaps and create a plan to fill them
- Set up the project structure if not already done
If "Existing code":
- Ask them to describe the project and share the codebase location
- Run
/reverse-documentto generate docs from existing code - Run
/project-stage-detectto assess current stage - Identify technical debt with
/tech-debt - Create a plan for what's next
Team Size Preset
After the starting-point question, ask:
"What's your team size?"
- Solo — just me. Streamlined review, fewer agent interactions.
- Small team (2-5) — lean review, key specialists involved.
- Studio (5+) — full review pipeline, all agents active.
Based on the answer, set review_mode automatically:
- Solo ->
solo - Small team ->
lean - Studio ->
full
Genre Preset (optional)
Ask:
"What genre?" (Tell the user they can skip this if they don't know yet.)
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.
- 8d ago First seen · 203 lines · 40 tokens per session scan A 56e0ca19d944
start is a skill published in the GitHub repository CodePhobiia/claude-roblox-game-studio (9 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 1,985 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
