Ask Callan something hard.
Go service RSS climbs 40MB/hour until OOM, but the pprof heap profile looks flat. Where does memory hide that heap can't see?
CLAUDE · AS CALLAN, GOLANG 開發人員
Flat heap with climbing RSS means the memory isn't in live heap objects - usual hiding spots: goroutine leaks (each parked goroutine holds its stack; watch runtime.NumGoroutine over an hour - 40MB could be a few thousand of them), unbounded channel buffers, and CGO allocations pprof never sees. Take two goroutine profiles an hour apart and diff: leaked goroutines cluster on the same channel receive or mutex. If it's goroutines, the cure is context cancellation on every spawn - a goroutine without a cancel path is a leak that hasn't happened yet. Paste the profile's top 10 and I'll spot the parked family.

Callan 的功能
Callan 會將 Claude（或 ChatGPT，或任何 AI 聊天工具）轉變為資深 Go 後端工程師，根據真實證據診斷 goroutine 洩漏、channel 死結、錯誤處理結構，以及 gRPC/REST 之間的取捨，然後提供具體且可立即執行的計畫。
適用對象
負責執行正式環境 Go 服務的後端工程師與創辦人，需要正確處理並行、錯誤處理，或 gRPC/REST API 設計決策。
主要功能
- Goroutine 與 channel：生命週期所有權、「由傳送者關閉」規則、工作池，以及經典的洩漏模式
- sync 套件：根據實際的並行問題，選用 Mutex/RWMutex、WaitGroup、sync.Once 與 sync/atomic
- 錯誤處理慣用法：使用 %w 包裝錯誤、sentinel 錯誤、自訂錯誤類型，以及使用 errors.Is/errors.As 而非字串比較
- 專案結構與套件設計：cmd/internal/pkg 佈局、避免 import cycle，以及以建構函式為基礎的依賴注入
- 使用 pprof 進行效能剖析：CPU 與堆積剖析、goroutine 傾印，以及用基準測試結果（ns/op、allocs/op）驗證所宣稱的修正
- gRPC 與 REST API 設計：protobuf 版本控制、單一請求與串流 RPC，以及針對每個服務邊界選擇合適的通訊協定
使用方式
下載技能檔案，並將完整內容貼到 Claude 專案指示（或任何 AI 聊天工具的 system prompt）中。接著以自然語言描述你的問題，即可獲得具體且可立即執行的計畫 - 不必每次工作階段重新解釋背景。適用於 Claude、ChatGPT 與任何 AI 聊天工具。安裝時間不到 2 分鐘。

關於此產品的問題
What AI tools does this work with?+
Claude, ChatGPT, or any AI chat that accepts a system prompt or Project Instructions. Claude Projects gives the best results.
How do I install it?+
Paste the SKILL.md contents into your Claude Project Instructions or system prompt. Under 2 minutes, no setup required.
Is this a course or a tool?+
It's a single skill file, not a course. Load it once and Callan applies the same expertise and methodology from the first message of every session.
Can Callan find why my goroutine is leaking?+
Yes. Callan traces every goroutine to its owner and exit path, a channel with no receiver, a context that's never cancelled, an unclosed range, and names the exact leak shape and fix.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
準備好讓您的 AI 專精了嗎？
一個即插即用的檔案。一次付費，永久保留 - 適用於 Claude 和 ChatGPT。
