Ask Codex

Executes the local codex CLI to get coding assistance.

Note: This skill requires the codex CLI to be installed and available in your system's PATH.

Quick start

Run a single query with codex exec:

codex exec "Your question or task here"

Common options

| Option | Description | |--------|-------------| | -m MODEL | Specify model | | -C DIR | Set working directory | | --full-auto | Enable automatic execution with workspace-write sandbox |

For all available options, run codex exec --help

Examples

Ask a coding question:

codex exec "How do I implement a binary search in Python?"

Analyze code in a specific directory:

codex exec -C /path/to/project "Explain the architecture of this codebase"

Use a specific model:

codex exec -m o4-mini "Write a function that validates email addresses"

Let Codex make changes automatically:

codex exec --full-auto "Add error handling to all API endpoints"

Notes

• Codex runs non-interactively with exec subcommand
• By default, output goes to stdout and no files are modified without approval
• Use --full-auto for automatic execution within sandbox constraints
• The command inherits the current working directory unless -C is specified
