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.

What it costs to keep this loaded
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 | $0.00036 | $0.00691 |
| Opus 5 | $0.00018 | $0.00345 |
| Sonnet 5 | $0.00007 | $0.00138 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
roblox-cloud 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 9d 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.

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Roblox Open Cloud
When to Load
Load for Open Cloud, API keys, OAuth, webhooks, or supported HttpService. Route in-game data work to roblox-data and roblox-server-data; gameplay and Studio work to domain skills.
Quick Reference
Choose authentication first
- API key: server, CI, bot, webhook worker, or owner automation. Scope to required resources and operations.
- OAuth 2.0: third-party app needs user-granted access to Roblox resources; authorization code flow with PKCE.
- Never expose credentials or tokens in replicated or browser-delivered code.
REST mechanics
- Resources generally use
https://apis.roblox.com/cloud/v2/...; confirm each endpoint and legacy v1 exceptions. - Read
nextPageToken; send it back aspageTokenunchanged. - Use
updateMaskonly for fields intended to change. - Poll returned Operations with bounded backoff.
- Treat 429 and
RESOURCE_EXHAUSTEDas quota signals; honorRetry-After.
OAuth essentials
- Register exact redirect URLs and minimum scopes.
- Fresh high-entropy
state+ PKCE verifier/challenge per attempt. - Verify
statebefore exchanging the single-use code. - Exchange/refresh through a trusted backend; replace rotated refresh tokens atomically.
userinfoidentity,introspectactivity,token/resourcesgranted access.- Reauthorize on scope change; revoke on disconnect.
Public clients cannot hold a secret and require PKCE. Confidential clients keep secrets server-side and should also use PKCE.
Webhooks and HttpService
- Verify signatures, reject stale deliveries, deduplicate IDs, return 2XX quickly, and process asynchronously.
- In-experience: confirm HttpService support. Use HTTPS and a Roblox Secret for
x-api-key.
Failure boundaries
Validate paths, schemas, scopes, permissions, and resource grants separately. Retry only transient failures.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 9d ago First seen · 61 lines · 36 tokens per session scan A 419b8573100c
roblox-cloud is a skill published in the GitHub repository TabooHarmony/roblox-brain (42 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 691 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 2026-08-30.
