Stop Wrapping Errors in TypeScript. Use `cause` Instead.

ES2022 gave JS a built-in way to chain errors. Most TypeScript codebases still ship custom wrap helpers. Here is the swap, with gotchas.

DeepClaude: I Combined Claude Code with DeepSeek V4 Pro in My Agent Loop and the Numbers Threw Me Off

I took the DeepClaude repo (467 points on HN) and dropped it into my real production loop. The combination isn't simply "better than either alone" — there's a specific task regime where DeepSeek V4 Pro destroys and Claude fails, and vice versa. Here are my actual numbers.
