Use when the user asks how to build with OpenAI products or APIs, asks about Codex itself or choosing Codex surfaces, needs up-to-date official documentation with citations, help choosing the latest model for a use case, latest/current/default-model prompting guidance, or model upgrade and prompt-upgrade guidance; use OpenAI docs MCP tools for non-Codex docs questions, use the Codex manual helper first for broad Codex self-knowledge, and restrict fallback browsing to official OpenAI domains.
Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).
Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, valid manifest defaults, and personal-marketplace entries by default. Use when Codex needs to create a new personal plugin, add optional plugin structure, generate or update marketplace entries for plugin ordering and availability metadata, or update an existing local plugin during development with the CLI-driven cachebuster and reinstall flow.
Split the current git worktree into one or more meaningful commits with clean staging boundaries and commit hygiene. Use when the user asks to commit current changes, wants related changes grouped into multiple commits, or needs help preparing commit messages without disturbing unrelated local modifications.

Guide for creating effective skills. This skill should be used when users want to create, update, review, and debug native Zsh completion scripts built on the modern completion system (`compsys`). Use when Codex needs to create a new `_command` completion function, extend subcommand, option, or argument completion, fix completion parity against a CLI's current help output, migrate legacy `compctl` behavior to `#compdef` or `compdef`, or diagnose matcher, style, tag, or context issues in existing Zsh completion code.
