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 |
-s workspace-write | 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 gpt-5.5 "Write a function that validates email addresses"
Let Codex make changes automatically:
codex exec -s workspace-write "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
-s workspace-write for automatic execution within sandbox constraints
- The command inherits the current working directory unless
-C is specified
