## What it does

The skill sets architecture patterns for interacting with `https://apis.roblox.com/cloud/v2/`. It outlines proper handling of `nextPageToken` during pagination, targeted updates with `updateMask`, and respecting quota limits signaled by 429 status codes or `RESOURCE_EXHAUSTED` responses with `Retry-After`.

For authentication, it defines strict flows for OAuth 2.0. Public clients must use PKCE with high-entropy state validation. Refresh tokens require atomic replacement on backend rotation, while incoming webhooks need signature checks and immediate 2XX returns.

Never place credentials in replicated scripts or client-facing code. Inside an experience, requests via `HttpService` must source the `x-api-key` header directly from Roblox Secrets.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-cloud -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/roblox-cloud/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/roblox-cloud/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-cloud -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/roblox-cloud/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-cloud -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/roblox-cloud/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TabooHarmony/roblox-brain roblox-cloud
```

2. **Manually: put the files in place**
- File: `.github/skills/roblox-cloud/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-cloud -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TabooHarmony/roblox-brain --path skills/tools/roblox-cloud
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/roblox-cloud/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-cloud -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/TabooHarmony/roblox-brain/tree/HEAD/skills/tools/roblox-cloud/SKILL.md

## When to use it
- configure Roblox OAuth 2.0 authorization code flow with PKCE
- read and update Roblox DataStore records from external servers
- verify signatures and deduplicate incoming webhook deliveries
- automate place publishing and asset management via Open Cloud API

## Example prompts
- Write an Express service that exchanges Roblox OAuth 2.0 codes using PKCE
- Create a Python script to read player DataStore records via Open Cloud v2
- Implement a webhook receiver for Roblox events with signature verification

# Roblox Open Cloud

## When to Load

Load for Open Cloud, OAuth, webhooks, HttpService, or teleport handoffs. In-game data: `roblox-data` and `roblox-server-data`.

## 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 as `pageToken` unchanged.
- Use `updateMask` only for fields intended to change.
- Poll returned Operations with bounded backoff.
- Treat 429 and `RESOURCE_EXHAUSTED` as quota signals; honor `Retry-After`.

### OAuth essentials

1. Register exact redirect URLs and minimum scopes.
2. Fresh high-entropy `state` + PKCE verifier/challenge per attempt.
3. Verify `state` before exchanging the single-use code.
4. Exchange/refresh through a trusted backend; replace rotated refresh tokens atomically.
5. `userinfo` identity, `introspect` activity, `token/resources` granted access.
6. 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.
