Usage of OpenAI

Summary

OpenAI/Codex usage in this vault is mainly about slash commands, skills, and a small set of config files.

In this vault, AGENTS.md controls agent behavior and SKILL.md files define reusable workflows.
In API projects, key files are requirements.txt or pyproject.toml, env files (env or .env), app entry files, and README.md.
Never hardcode API keys; keep them in environment variables (OPENAI_API_KEY).
Keep prompts and model settings in dedicated config/prompt files for maintainability.
Slash command availability can vary by Codex version and surface (CLI, app, IDE extension).

Show all available slash commands in your current client: Type / in the input box, or type ? for shortcuts.
Core commands commonly available in Codex: /init, /status, /approvals, /model, /mcp, /mode, /clear, /diff, /skills.
About experimental: It is often a mode/value (for example a thinking display option) rather than a standalone slash command, depending on version.
Skill usage pattern: /skills to list skills, then invoke a specific skill with $skill-name.
