샘플 구성

이 예시 구성을 출발점으로 사용하세요. 여기에는 대부분의 Codex가 config.toml에서 읽는 키들과 기본값 및 간단한 설명이 포함되어 있습니다.
설명 및 안내는 다음을 참고하세요:
아래 스니펫을 참고하세요. 필요한 키 및 섹션만 ~/.codex/config.toml(또는 프로젝트 범위 .codex/config.toml)에 복사한 뒤 설정에 맞춰 값을 조정하세요.
# Codex example configuration (config.toml)
#
# This file lists all keys Codex reads from config.toml, their default values,
# and concise explanations. Values here mirror the effective defaults compiled
# into the CLI. Adjust as needed.
#
# Notes
# - Root keys must appear before tables in TOML.
# - Optional keys that default to "unset" are shown commented out with notes.
# - MCP servers, profiles, and model providers are examples; remove or edit.
