Cli Creator

Skill Verified Active

Build a composable CLI for Codex from API docs, an OpenAPI spec, existing curl examples, an SDK, a web app, an admin tool, or a local script. Use when the user wants Codex to create a command-line tool that can run from any repo, expose composable read/write commands, return stable JSON, manage auth, and pair with a companion skill.

Purpose

To enable users to create custom, reusable command-line interfaces that Codex can leverage for specific tasks, ensuring consistency, security, and ease of use.

Features

Generates composable CLIs from diverse sources (API docs, OpenAPI, SDKs, scripts).
Supports multiple runtime environments (Rust, TypeScript/Node, Python).
Defines clear command contracts with discovery, read, write, and escape hatch commands.
Guides secure authentication and configuration practices for generated CLIs.
Provides detailed instructions for building, installing, and testing the generated CLIs.

Use Cases

When a repeatable command-line tool is needed for managing a service or API.
To create a unified interface for multiple data sources or scripts.
When Codex needs to interact with custom internal tools or scripts from any repository.
To build durable, versionable command-line utilities with predictable JSON output and auth.

Non-Goals

Creating one-off scripts that are not intended for durable use.
Building CLIs that do not adhere to defined command contracts or security best practices.
Replacing existing package managers or language runtimes with custom solutions.
