C++ Templates

Purpose

Guide agents through reading and fixing template error messages, using concepts as cleaner constraints, understanding SFINAE vs concepts trade-offs, and profiling template instantiation depth and compile times with Templight.

Triggers

• "How do I read this massive C++ template error?"
• "How do I use concepts to constrain a template?"
• "What's the difference between SFINAE and concepts?"
• "My templates make compilation very slow"
• "How do I write a requires-clause?"
• "How do I profile template instantiation times?"

Workflow

1. Reading template error messages
