A skill collection for AI agents that helps with daily life in Japan. It focuses on lookup skills that use only official APIs and public data — such as the Japan Meteorological Agency's open data, the Cabinet Office's holidays CSV, and the Calil library API — and are safe to use without login.
Works with coding agents that support npx skills add (Claude Code, Codex, OpenCode, and others).

| What you can do | Skill | Description | Login | Docs |
|---|---|---|---|---|
| Look up weather forecasts in Japan | jma-weather | Fetches weather, precipitation probability, and temperature forecasts from the JMA's public JSON | Not required | jma-weather guide |
| Look up earthquake bulletins and weather warnings | bosai-alert | Fetches JMA disaster info (earthquake list & details, warnings/advisories, tsunami info) | Not required | bosai-alert guide |
| Look up national holidays and long weekends | japan-holidays | Calculates holidays, substitute holidays, and long weekends from the Cabinet Office's official CSV | Not required | japan-holidays guide |
| Estimate your furusato nozei donation cap | furusato-nozei | Calculates an estimate of the hometown tax donation limit from salary income and taxable income (no API needed) | Not required | furusato-nozei guide |

The canonical source for each skill is <skill>/SKILL.md. The guides in docs/features/ are summaries — always refer to SKILL.md for detailed procedures, parameters, and error handling.
Scope notes:
- Services with strong anti-scraping measures (Mercari, SUUMO, transfer guides, Tabelog, etc.) are out of scope.
- No state-changing operations (reservations, purchases, posts) are handled. Only lookups and calculations.
- Weather and disaster data are retrieved from JMA announcements as-is. Always check official JMA bulletins for final decisions.

30-day build-in-public challenge in progress
This repository is growing as a 30-day build-in-public challenge: one skill a day, with each commit doubling as a Qiita article. Frankly, the biggest risk factor is whether the quota of Astra — the AI agent co-authoring this series — survives all 30 days.
