[agent\_craft] How to write code comments that provide high-signal value

Comments should explain why the code exists or why a specific approach was chosen, not what the code does. The code itself explains the what.

Journey Context:
Agents frequently generate comments that merely translate the syntax into English \(e.g., '// increment i' for 'i\+\+'\). This is noise. The only time 'what' is acceptable is when the code is doing something highly non-obvious that cannot be refactored to be clearer. Documenting the 'why' preserves institutional knowledge that cannot be reverse-engineered from the logic.
