What it does

This skill teaches an AI agent to operate Japan Post's Web Yu-pri shipping label system through a command-line tool that controls a real browser. The agent can open a login page so you sign in yourself, check the page status, take screenshots, plan item entries from a JSON or CSV list, and fill in the repetitive contents lines of a shipment form. It is designed to do a dry run first and never presses the final shipment or purchase buttons.

Great for

  • Staff who enter many similar contents lines into Yu-pri labels for repeat shipments
  • Developers automating Japan Post label entry who want a dry-run check before live filling
  • Users who already have a Japan Post business account and can log in manually

Skip it if

  • Anyone wanting fully unattended submission, since the skill deliberately stops before final confirmation and the site may change layout and break selectors
  • Users who would need to store Japan Post passwords in scripts or prompts, which the skill explicitly forbids for safety
  • Situations where the declared values or customs details are not verified, because wrong declarations can cause shipping or customs problems

Try asking

  • “Run a dry-run plan of my items.json contents before filling the Yu-pri form”
  • “Open the Japan Post login page so I can sign in, then check the status of the contents page”
  • “Fill the contents lines from my CSV of award plaques and certificates with a total declared value of 17000 yen”
  • “Take a screenshot and dump the HTML of the Yu-pri contents page to diagnose selector problems”

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Always run contents fill with --dry-run --json and review the output before a live fill
  • Log in yourself through open-login rather than giving the agent your credentials
  • Use --value-mode unit only when the value is a per-unit price that should be multiplied by quantity
