  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads roblox-oauth automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

roblox-oauth

When to Load

Load this skill when the task centers on Roblox OAuth 2.0 delegated authorization for Open Cloud — app registration, authorization code flow with PKCE, token exchange/refresh/revocation, scope selection, or OAuth-specific error debugging. Skip it for API-key automation, in-experience scripting, or general Open Cloud endpoint work (use roblox-cloud instead).

Quick Reference

Flow Selection

  • Auth Code + PKCE — required for public clients (browser/mobile), recommended for all.
  • Confidential — backend holds client_secret; never expose in frontend code.
  • Public — no secret; PKCE mandatory.

PKCE Essentials

  • Generate code_verifier (43–128 char random) + code_challenge (SHA-256, base64url).
  • Send code_challenge + code_challenge_method=S256 in authorize; send code_verifier in token exchange.
  • One verifier per authorization attempt.

Authorization URL

GET https://apis.roblox.com/oauth/v1/authorize Params: client_id, redirect_uri, scope, response_type=code, code_challenge, code_challenge_method=S256, state, optional nonce.

Token Exchange

POST /oauth/v1/token — application/x-www-form-urlencoded Params: grant_type=authorization_code, code, client_id, code_verifier (public) or client_secret (confidential).

Token Lifecycle

  • Auth code — seconds, single-use; exchange immediately.
  • Access token — ~15 min; use as Bearer.
  • Refresh token — ~90 days; single-use per refresh. Replace stored token atomically after each refresh.
  • Revoke: POST /oauth/v1/token/revoke on disconnect.

Scope Selection

  • Minimum scopes matching actual endpoint needs.
  • openid → ID token; profile only if profile claims needed.
  • Medium/high/critical risk = least-privilege review signal.
  • Changing scopes requires reauthorization.

Validation Endpoints

  • GET /oauth/v1/userinfo — identity claims.
  • POST /oauth/v1/token/introspect — token activity (not resource auth).
  • POST /oauth/v1/token/resources — resource-level access.

Key Rules

  • Verify state before using returned code.
  • Refresh tokens: server-side only.
  • PKCE even for confidential clients.
  • Don't mix API keys and OAuth. Need more detail? Load references/full.md for the complete reference with code examples, API tables, and edge cases.

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
