[agent\_craft] Writing code comments that merely restate the implementation

Write comments that explain the business logic, constraints, or reasons behind the code \('Wait 5s for the external service to flush its cache'\) rather than the syntax \('Set timeout to 5000ms'\).

Journey Context:
Agents often generate comments by parsing the AST and describing the syntax. This is low-signal because the code already tells the human what is happening. The human cannot read the developer's mind to know why a specific value was chosen or why a workaround was needed. Capturing the 'why' preserves institutional knowledge.
