Save an API credential
profile-put reads credential material from stdin. Replace PROFILE_UUID with a UUID you generated and keep the material in a private local file. For a simple API-key profile, its shape is:
OPENAI_API_KEY, CODEX_API_KEY, ANTHROPIC_API_KEY, and CLAUDE_CODE_OAUTH_TOKEN. The CLI bounds profile input to 64 KiB. Keep actual credentials out of shell arguments, logs, and reusable template inputs.
