All 15 static findings are false positives involving Markdown formatting, legitimate downloads, fixed shell commands, and a documentation link. No evidence found of prompt injection, credential access, or data exfiltration. A separate low-severity concern is archive extraction that can overwrite local files without isolating the destination.

Archive Extraction Can Overwrite Local Files

The workflow uses unzip -o in the current directory without validating archive contents. A supplied archive can overwrite matching local files during extraction.

The overwrite option and user-supplied archive fallback are explicit. Impact depends on archive contents and existing files; no malicious archive is shown.

Lo que puedes crear

Check Postal Address Fields

Compare a customer's town and postal code against official postal data before updating an address record.

Review Japanese Address Data

Find postal codes for town-name entries and identify ambiguous matches during data cleanup.

Look Up a Town's Postal Code

Search a Japanese town name locally without creating an account or requesting an API key.

Prueba estos prompts

Look Up One Postal Code

Find the address for postal code 1000001 using Japan Post's UTF-8 dataset. Include all matches and the dataset month if known.

Search by Town Name

Find postal codes for Marunouchi in Chiyoda City, Tokyo. Search the Japanese town name and include every matching town entry.

Review Multiple Matches

Search the local dataset for postal code [seven-digit code]. Return every matching prefecture, municipality, and town, including any catch-all entry.

Refresh and Verify Local Data

Refresh Japan Post's UTF-8 dataset in a dedicated directory and record its source and download date. Compare [town] matches with my existing dataset.

Mejores prácticas

Use the official UTF-8 dataset and extract archives into a dedicated directory after checking their contents.
Record the dataset month when available and the download date; refresh approximately monthly.
Return every matching row and distinguish postal notation from residential address notation.

Evitar

Guessing postal codes or download URLs when official data is unavailable.
Treating the first match as the only result for a shared postal code.
Extracting an unchecked archive over unrelated workspace files.

Preguntas frecuentes

Which country does this skill cover?

It covers Japanese postal codes and town addresses using Japan Post's official KEN_ALL dataset.

Do I need an API key or account?

No. The workflow downloads public postal data and searches the CSV locally.

Can I search by address instead of postal code?

Yes. Partial town-name searches can return matching postal codes. Adding a prefecture and municipality helps distinguish similar names.

Why might a hosted agent fail to download the archive?

The author observed archive download failures from datacenter IP addresses. Downloading on your own computer is a documented fallback.

How often should I update the dataset?

Japan Post updates the data monthly. Refresh approximately monthly and report the dataset month when known.

Does it print labels or verify complete street addresses?

No. It searches postal-code address records. Label printing, shipping, and complete residential address validation are outside its scope.
