Piping Patterns
# stdout is always clean data — safe to pipe
mmx text chat --message "Hi" --output json | jq '.content'
# stderr has progress/spinners — discard if needed
mmx video generate --prompt "Waves" 2>/dev/null
# Chain: generate image → describe it
URL=$(mmx image generate --prompt "A sunset" --quiet)
mmx vision describe --image "$URL" --quiet
# Async video workflow
TASK=$(mmx video generate --prompt "A robot" --async --quiet | jq -r '.taskId')
mmx video task get --task-id "$TASK" --output json
mmx video download --task-id "$TASK" --out robot.mp4
Configuration Precedence
CLI flags → environment variables → ~/.mmx/config.json → defaults.
# Persistent config
mmx config set --key region --value cn
