## Capabilities

- Direct the assistant to official tables for domestic letters, parcels, express mail, and international letters.
- Guide domestic letter rate lookup by weight tier and ordinary, registered, or time-limited service.
- Explain postcard, letter sheet, registration, and time-limited service charges using fetched tables.
- Provide an HTTPS download example and guidance for parsing nested HTML tables and normalizing full-width characters.
- Require the assistant to ask for missing weight and report the service type, applicable tier, and query date.
- Guide honest reporting of unavailable sources and uncertain international rate zones.

## Use Cases

- Estimate Personal Mailing Costs: Check ordinary and registered domestic letter costs from the current official table before mailing personal documents.
- Check Domestic Parcel Rates: Find the official domestic parcel table and identify the information needed to estimate shipping charges.
- Plan International Letter Mailing: Consult international letter tables by destination and weight, and disclose uncertainty when the rate zone is unclear.

## Prompt Templates

### Check a Postcard Rate

```
What is the current postage for one ordinary domestic postcard in Taiwan? Use the official table and include the query date.
```

### Compare Letter Services

```
Compare ordinary and registered postage for a 20-gram domestic letter in Taiwan. Show the weight tier, registration charge, source, and query date.
```

### Prepare a Parcel Estimate

```
Help estimate postage for a 2-kilogram domestic parcel in Taiwan. Ask for missing route or packaging details and consult the official parcel table.
```

### Check an International Letter

```
Check ordinary and registered rates for a 50-gram letter from Taiwan to Japan using current official tables. Report the zone, surcharges, and uncertainties.
```

## Limitations

- Requires an assistant with network access and suitable retrieval tools; the skill supplies instructions rather than a standalone calculator.
- Does not support shipment tracking or post office location searches.
- Rates and page structures may change; recorded examples do not establish current prices.
- International letter quotes require destination zone information; the skill does not provide international parcel or EMS rate tables.

## Best Practices

- Provide mail type, weight, service, and destination before requesting a quote.
- Fetch the current official table and include the source, query date, and applicable weight tier.
- Use a private temporary file for downloads and report source failures or uncertain destination zones explicitly.

## Anti Patterns

- Treating the skill's dated sample rates as verified current prices.
- Guessing weight tiers, registration charges, or international destination zones.
- Using this skill for shipment tracking or post office location searches.

## Security Audit

- Audited at: 2026-10-13T03:54:58.993\+00:00
- Summary: Eleven alerts are false positives: Markdown backticks, readable multilingual text, and official HTTPS references do not demonstrate malicious behavior. The fixed temporary output path creates a local symlink overwrite risk when the documented command runs. No evidence found of credential theft, data exfiltration, or prompt injection.
