Course schedule
1 Introduction to the Codex Ecosystem
- Codex's Position in the OpenAI Ecosystem.
- Architecture: CLI, IDE extension, cloud, integrations.
Hands-on work
Overview of Codex interfaces. First interaction with the agent. Installation via npm or Homebrew.
2 An In-Depth Look at Codex CLI
- Essential keyboard shortcuts.
- Navigating the terminal interface.
Hands-on work
Explore an unfamiliar project with Codex. Ask for explanations about the architecture. Generate documentation automatically. Work on a task across multiple sessions. Use the previous context to continue.
3 Control and Safety
- Manage approval modes.
- The three levels: Read-only, Auto (default), Full Access.
Hands-on work
Test the different permission levels. Observe how the agent behaves depending on the mode. Test the sandbox restrictions. Configure targeted access.
4 AGENTS.md and Customization
- Purpose of the AGENTS.md file: a README for agents.
- Create an AGENTS.md file for the Fil Rouge project.
Hands-on work
Write an effective AGENTS.md file for building a simple application.
5 IDE and Cloud Extension
- The VS Code extension.
- Modes: Chat, Agent, Agent (Full Access).
Hands-on work
Install and configure the extension. Codex-assisted refactoring. Generate unit tests. Code navigation and explanation.
6 MCP and GitHub Integration
- Understanding the MCP: Connecting Models to External Tools.
- Configuration in config.toml.
Hands-on work
Set up an MCP documentation server (Context7). Add a custom MCP server using `codex mcp add`. Use MCP tools in a Codex session. GitHub: Enable automatic review on a PR. Customize review guidelines.
