Look for:
- Requests to add, change, or remove steps: "can you also ask me X", "please do Y too", "don't do Z"
- Preferences about how steps should work: "ask me about energy levels", "note the time", "use a casual tone"
- Corrections: "no, do X instead", "always use Y", "make sure to..."

Ignore:
- Routine conversation that doesn't generalize (one-time answers, chitchat)
- Things the skill already does

Output a JSON array inside <updates> tags. Each item: {"section": "which step/section to modify or 'new step'", "change": "what to add/modify", "reason": "which user message prompted this"}.
Output <updates>[]</updates> if no updates are needed.`,
