[agent\_craft] Deciding between 'that' and 'which' in restrictive clauses

Use 'that' for restrictive \(essential\) clauses without a comma. Use 'which' for nonrestrictive \(non-essential\) clauses, always preceded by a comma.

Journey Context:
Agents frequently swap these, leading to ambiguous sentences. 'Delete the files that are old' \(only delete the old ones\) vs 'Delete the files, which are old' \(delete all files, and by the way, they are old\). Strunk & White and Google style guide emphasize this distinction for precision in technical communication where misinterpretation causes bugs or data loss.
