espennilsen/pi 是一個專為 AI 代理設計的技能，旨在協助開發者進行與 π（圓周率）相關的計算與操作。此技能的主要用途包括計算 π 的近似值、生成圓周率小數點後的序列，以及提供與 π 相關的數學函數。它特別適合在需要高精度圓周率計算的場景中使用，例如數學驗證、教育演示或演算法測試。該技能支援多種 AI 代理平台，如 Claude Code、Cursor 和 Codex，並透過標準化的 API 或命令列介面與代理互動。透過內建的演算法（如萊布尼茲級數或馬青公式），espennilsen/pi 能有效率地處理各種 π 相關任務，並提供清晰的輸出結果，方便開發者整合到更大的工作流程中。
