Open a diary from ten years ago and the first thing you miss is the weather. "Walked to the station" means something different in sleet than in June sun, and you never wrote it down because it was obvious at the time. This is the easiest thing to hand to an agent, and the most pleasant to read back.
🌤️ What it looks like
Every morning a line appears on today's page in a planner called Weather: "Cloudy, 18°C, light rain after 4 pm. Sunset 6:42." It carries a small via muse chip, so you always know you did not type it. Your own entries sit beneath it, in your own words. On the month view the day gets a dot like any other entry, so a wet week looks like a wet week.
📱 Way one: tell Muse once
If you use Meta's Muse, switch on Settings → Cloud access for agents in Dayleaf, create an API key, and give Muse the connector prompt from the developer page. Then say:
"Every morning at 7, write yesterday's weather for where I was into my Dayleaf Weather planner. One sentence, Celsius, mention sunset."
That is the whole setup. Muse remembers the routine and the journal fills in from then on, on your phone, your Mac and your Android tablet at the same time.
🖥️ Way two: a cron job on the Mac
If you would rather not involve an assistant at all, the dayleaf command line and a free weather service do it in one line. Switch on Headless Dayleaf in the Mac app's Settings, copy the token, then:
npm install -g dayleaf
dayleaf auth <token>
# 06:30 every day, from crontab -e:
30 6 * * * curl -s "wttr.in/San+Jose?format=%C+%t,+wind+%w" | xargs -I{} dayleaf add "{}" --planner Weather --source wttrThe --source flag is what paints the chip. Use anything you like; "wttr" is honest.
🤖 Way three: let Claude do it when you ask
With the MCP server attached to Claude Desktop or Claude Code (claude mcp add dayleaf -- npx -y dayleaf-mcp), you can just say "log today's weather in my Weather planner" whenever you think of it. Claude looks the weather up, writes the line, and the chip says via claude.
Why a separate planner
Keep agent-written lines in their own planner. It gets its own colour on the calendar, you can hide it with one tap when you want only your words, and your Year in Review counts it separately. Your streak is still yours: agent entries do not count toward it.
