Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.00684 |
| Opus 5 | $0.00051 | $0.00342 |
| Sonnet 5 | $0.00020 | $0.00137 |
| Haiku 4.5 | $0.00010 | $0.00068 |
Grade A, and why
power-news scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
制度改正のウォッチ。scripts/power_watch.py で公式公表物の新規分を取得し、各件を読んで汎用の業界影響を要約する。監視対象には METI 制度検討作業部会・EGC 制度設計・監視専門会合に加え、容量市場やΔkW上限価格の実質的な決定の場となっている電力安定供給ワーキンググループ、中長期取引市場検討ワーキンググループも含む（詳細は regwatch スキル参照）。
手順
- 取得:
python "${CLAUDE_PLUGIN_ROOT}/scripts/power_watch.py"（引数なしで3ソース、--sourcesで限定、--allで state 無視の全件）。 - 出力の各
[source] date title urlについて、必要なら url を開いて内容を確認。 - 各件を汎用サマリで報告: 「〈委員会/回次・日付〉: 〈テーマ〉。電力業界への影響（一般論）。原文: url（要確認）」。
- 新規が無ければ「新規公表物なし」。取得失敗ソースは「取得不可（要確認）」と明示。
原則
- 会社固有の解釈・社内判断は書かない（汎用の業界影響のみ。個社への当てはめは利用者が自分の文脈で）。
- 数値・日程は原文・公式で要確認。要約はLLMのため誤りうる旨を添え、原文リンクを必ず併記。
www.meti.go.jp・www.egc.meti.go.jpは AWS WAF の JS チャレンジで自動取得が通らないことがある。その場合は沈黙せず「取得不可（要確認・手動確認要）」と明示する。ΔkW上限価格はEPRX上限価格ページ（https://www.eprx.or.jp/information/post.php）が1次公表元で自動取得しやすい。- 定期実行のオン/オフは
scripts/power_brief_schedule.pyと同様のスケジューラ登録で行う（既定はオフ＝手動実行）。
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

power-news is a command published in the GitHub repository muji-j/jp-power-tools (1 stars, last pushed 1mo ago), licensed MIT. It adds 102 tokens to every session and 684 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
