The AI-First and Codex Full-Process Practice Course is a systematic course built around AI-First thinking, Codex hands-on work, prompt engineering, an Obsidian knowledge base, Skills and AI automated workflows. Starting from basic concepts - LLMs, prompts, context, tokens, multi-turn dialogue, hallucination and agents - it gradually builds Codex core settings and the method of turning vague needs into precise instructions; then it teaches organizing fragmented information into reusable Skills, turning one idea step by step into a complete solution. The knowledge-management part systematically covers Obsidian notes, bidirectional links, retrieval, Web Clipper, AI material integration and multi-platform content production, further connecting AI to build a personal knowledge base. The advanced stage focuses on Skill creation and optimization, plugin use, workflow chaining, Codex video editing, PPT making, HyperFrames short-video generation, and combining tools like Claude Code, DeepSeek and Hermes - finally establishing the AI-First way of working: state a need, AI executes, knowledge accumulates, Skills are reused, and workflows automate.
