courseskills

Course creation skills for Codex and Claude Code. This repository packages the same workflows as both clients' plugin formats and as standalone Claude Code skills.

Skill	What it does
ai-tutorials	Design AI course syllabi, lectures, and hands-on projects
codex2course	Topic / outline -> handout -> Imagegen slide images -> PDF
api2course	Topic / outline -> handout -> OpenAI API slide images -> PDF
pdf2video	Slide deck -> per-slide narration -> TTS audio -> mp4
movecourse	Copy generated lesson mp4 files into the aistudy101 website course-assets tree

The repository is intentionally laid out around one shared skills/ directory:

• Claude Code can install the skills directly.
• Claude Code can also install this repo as a plugin through .claude-plugin/marketplace.json.
• Codex can install it from the Codex marketplace manifest at .agents/plugins/marketplace.json, which points back to .codex-plugin/plugin.json.

Install

Skills(Easy)

Requires Node.js. Restart Claude Code after installing.

npx skills add likefallwind/courseskills

Install one skill only:

npx skills add likefallwind/courseskills --skill ai-tutorials
npx skills add likefallwind/courseskills --skill codex2course
npx skills add likefallwind/courseskills --skill api2course
npx skills add likefallwind/courseskills --skill pdf2video
npx skills add likefallwind/courseskills --skill movecourse

Claude Code plugin

Use this if you want plugin-style namespacing and marketplace updates:

/plugin marketplace add likefallwind/courseskills
/plugin install courseskills@courseskills

Installed plugin skills are namespaced:

/courseskills:ai-tutorials
/courseskills:codex2course
/courseskills:api2course
/courseskills:pdf2video
/courseskills:movecourse

For local plugin development or testing:

claude --plugin-dir /path/to/courseskills

Codex plugin

Codex installs this repository through its marketplace system.

For Codex App on Windows, use Add marketplace with:

Source: https://github.com/likefallwind/courseskills.git
Git ref: main
Sparse paths: .agents/plugins

For Codex CLI:

codex plugin marketplace remove courseskills || true
codex plugin marketplace add \
  'https://github.com/likefallwind/courseskills.git' \
  --ref main \
  --sparse .agents/plugins

codex plugin list --source courseskills
codex plugin install courseskills --source courseskills

On Windows PowerShell, use codex.cmd instead of codex if PowerShell blocks .ps1 scripts.

For detailed Codex App, Windows CLI, WSL, Linux, and macOS setup notes, see docs/codex-install.md.

Prerequisites

codex2course

• Codex or Claude Code with the imagegen skill/tool available for slide image generation.

• Python 3 + Pillow for PDF assembly:

  pip install Pillow
  

api2course

• OPENAI_API_KEY set in the environment. The image script uses gpt-image-2.

• Python 3. The OpenAI image script uses only the standard library.

• Python 3 + Pillow for PDF assembly:

  export OPENAI_API_KEY=your_key_here
  pip install Pillow
  

pdf2video

• A completed slide deck from codex2course or api2course.

• ffmpeg on PATH for video assembly.

• TTS provider:

  • edge: free Microsoft Edge read-aloud voices via edge-tts.
  • minimax: paid API route. Requires MINIMAX_API_KEY and Python requests.

  pip install edge-tts requests
  export MINIMAX_API_KEY=your_key_here
  

movecourse

• An AI-generated course directory containing lessonN/*.mp4 files.
• The aistudy101 website checkout at /home/likefallwind/code/aistudy101-website.

Shared workflows

Both Codex and Claude Code use the same skills and output layout. The skills are incremental: they inspect what already exists and continue from the next missing stage instead of redoing approved work.

# ai-tutorials
Design a 10-lesson LLM application development course for CS undergrads.

# codex2course
Create a 6-hour Python async course for backend engineers.

# api2course
Use api2course to create a 6-hour Python async course with OpenAI API generated slides.

# pdf2video
Turn the course in ./course/ into a narrated lecture video, voice: zh-CN-YunxiNeural.

# Full course asset flow
Design a Vibe Coding course, build slides, then produce a narrated mp4.

# Publish generated videos only
Move only this generated course's videos to aistudy101 course-assets as ai-enlightenment.
