Non-interactive (CI/scripts)

codex exec "Fix all lint errors" codex exec --json "List all TODO comments"

## Key Concepts

| Concept | Description |
|---------|-------------|
| **Approval modes** | Auto, Read-only, Full Access — control what Codex can do |
| **Sandbox** | Filesystem/network isolation for safe execution |
| **Rules** | Starlark-based execution policies (`.codex/rules/`) |
| **Skills** | Task-specific capabilities (`.agents/skills/`) |
| **AGENTS.md** | Custom system prompts per repo/directory |
| **config.toml** | User/project config (`~/.codex/config.toml`) |
| **MCP** | Model Context Protocol server integration |
| **Multi-agent** | Spawn sub-agents for parallel work |
