Your Node.js Stack Traces Are Eating Your Context Window

A typical Node.js error stack trace is 30-50 lines. Your code caused maybe 3 of those lines. The other 27-47 are node:internal/modules/cjs/loader, node:internal/modules/run_main, and friends. Claude Code reads them all. Every at Module._compile frame. Every at node:internal/main/run_main_module frame. They add nothing to debugging but cost real tokens.
