9. 🗓️ GitHub が Copilot のすべての機能で Claude Opus 4.7、Gemini 3.5 Flash、Gemini 3.6 Flash、Kimi K2.7 Code を非推奨にした

10. 🔍 GitHub が Copilot のコードレビューを REST と GraphQL の API から呼べるようにしてリクエストごとに effort を指定できるようにし、既定の effort を Balanced にした

11. 📘 OpenAI が GPT-6 ファミリーのモデルガイドを公開し、モデル・effort・速度の選び方、プロンプトとスキルの書き方、長い実行を軌道に保つ方法をまとめた

12. 🧰 GitHub が VS Code 1.136〜1.140 での 9 月の Copilot のリリースを、オートメーションやエージェントのマージから Claude と Codex のセッションからのプルリクエストまでまとめた

13. 📚 Zenn の無料の 30 章の本が、/poteto-mode を支えるプレイブック・原則・スキルである Cursor の pstack を解説した
