Course Outline
Overview of OpenAI Codex CLI
- Definition of Codex CLI and its 2025 open-source Rust-based architecture
- Primary capabilities: prompt handling, file management, shell execution, and multi-step task automation
- Comparative analysis with Claude Code and other terminal-based agents
- Review of approval protocols and security boundaries for government use cases
Installation and Configuration
- Deployment procedures for macOS and Linux environments
- Configuration of API credentials for OpenAI and compatible service providers
- Integration with local inference engines via Ollama and Atomic Chat
- Establishment of secure connections to remote development infrastructure
Operational Command Structure
- Execution of single-prompt requests and multi-turn interactive sessions
- Performing read, write, and edit operations on source files via command input
- Initiating shell commands and managing piped data outputs
- Management of working directories and project context for consistent operation
Approval Protocols and Safety Measures
- Configuration of automatic, pre-execution confirmation, and manual approval modes
- Implementation of sandboxed environments and distinction between read-only and write-enabled sessions
- Secure handling of potentially destructive commands and file deletion processes
