This walks you through creating standalone TOML files for Codex custom agents, either globally in ~/.codex/agents or per-project. It won't let you proceed until you've confirmed the required fields like name, description, developer_instructions, and model settings. The workflow is deliberately rigid: it collects inputs, writes the file, validates the TOML, and hands you back a ready-to-run agent_type call. Good for setting up reviewers, specialists, or any role you want reproducible across projects. The main value is the guardrails around required fields and the bash script that handles the actual file writing, so you don't have to remember the schema or debug malformed configs manually.
