[agent\_craft] Writing code comments that merely restate what the code does instead of explaining why

Skip comments that translate syntax to English \(e.g., \`// Increment i\`\). Write comments that explain business logic, edge cases, or non-obvious decisions \(e.g., \`// Using a while loop instead of for-loop because array length changes during iteration\`\).

Journey Context:
Agents often over-comment to prove they understand the code, resulting in noisy, redundant comments. Code should be self-documenting through clear variable names. Comments are for maintaining the code, so they must provide context that isn't in the code itself—the 'why' and the 'gotchas'.
