[SKILL] - explain-reasoning
Runs AFTER a task/fix has been done. Retrospectively unpacks the engineering thought process behind the change - which clue, which chain of reasoning, which principle, how it would have been found without AI, how the user can catch it on their own next time. Use when the user says 'why did you do it this way', 'explain your chain of reasoning', 'how would I have found this', 'mentor me', 'reasoning', or when /explain-reasoning is invoked.
