/codex-exec - Execute Codex CLI Commands

**Easy wrapper for running Codex CLI commands from Claude Code with proper syntax.**

Usage

/codex-exec [analysis|edit|search|resume] "your task"
/codex-exec --model [gpt-5|gpt-5-codex] "your task"
/codex-exec --help

What This Command Does

**Executes Codex CLI commands with**:

✅ Correct syntax (always uses codex exec)
✅ Intelligent model selection
✅ Appropriate sandbox modes
✅ High reasoning effort
✅ Error handling

**CRITICAL**: Always uses `codex exec` not plain `codex` (required for Claude Code environment)
