This is my basic import from 1password to pass.

import.sh

#!/bin/bash
for uuid in $(op list items | jq '.[] | .uuid' -c -r); do
    item=$(op get item "$uuid")

    username=$(echo "$item" | jq '.details.fields | .[] | select(.designation=="username") .value' -r)
    pass=$(echo "$item" | jq '.details.fields | .[] | select(.designation=="password") .value' -r)
    url=$(echo "$item" | jq '.overview.url' -r)
    title=$(echo "$item" | jq '.overview.title' -r | sed s"/ /-/g")
    title=$(echo ${title,,})

    entry=$pass 
    entry+=$'\n\n'"username: $username"
    entry+=$'\n'"url: $url"
 
    echo "$title"
    echo "$entry" | pass insert 1password/$title -m
done
