What problem does it solve? It answers questions about OpenAI products, APIs, models, and Codex configuration using current official documentation instead of stale memory, with proper citations and explicit uncertainty when sources are unclear. ## Core Features & Use Cases - Official docs lookup: Searches and fetches pages from developers.openai.com, platform.openai.com, and learn.chatgpt.com, citing the exact page supporting each claim. - Model selection and migration: Resolves the latest model dynamically, preserves explicitly requested model targets, and provides tier-aware GPT-5.6 migration guidance with compatibility checks. - Codex self-knowledge: Fetches and caches the Codex manual via a Node.js helper for broad setup, configuration, and troubleshooting questions. - Use Case: When asked "should I migrate my app from GPT-5.4 to GPT-5.6", the skill fetches current official migration guidance, inventories usage sites, and produces a scoped migration plan with validation steps. ## Quick Start Ask a question about an OpenAI model, API feature, or Codex setting and request an answer grounded in official OpenAI documentation with citations.
