Previous system prompt asked for "warm, conversational, like a friend
writing a letter" which produced flowery preludes that buried the actual
data. Rewritten to:
- Lead with practical data (tasks, events, weather) — concrete and specific
- 4-7 sentences total, tight prose, no padding
- Recent moments / open threads mentioned briefly at the END as context,
not as the lead
- Voice: "competent assistant briefing the user" not "friend writing a letter"
- Close with a short journal invitation under 8 words
Also dropped max_tokens 600 -> 400 to bias toward concision.
