Compare this week's sleep and activity with last week's, next to how much the user worked, with honest small-sample caveats. Use for the Sunday 19:00 weekly-health-trend routine, or when the user asks for a weekly health trend, "week over week", or how work and sleep moved together.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Weekly health trend
Week over week: this week (the 7 days ending today) against the 7 days before.
## 1. Read
First ask whether the phone is still syncing:
```
walnut tools call health_status '{}'
```
- `connected: true`: go on.
- `connected: false` with `lastUploadAt` null (or no store at all): Apple Health
is not connected. Say so and stop.
- `connected: false` with a `lastUploadAt`: nothing has synced since that date
(`lastUploadAt` is the last sync). Say so first, then compare only what arrived
before it, and count the days after it as missing because the phone has not
synced, not as days without sleep or activity.
Then read the two weeks:
```
walnut tools call health_sleep '{"last_nights":14}'
walnut tools call health_daily '{"last_days":14,"metrics":"activity,vitals,workouts"}'
```
Split both answers into the two weeks yourself (the newest 7 entries are this
week). The time on tasks for the same 14 days:
```
walnut tools call time_summary '{"days":14}'
```
Use only these named reads. If one is refused, say what was refused and stop:
health data is only available to sessions on this Mac, and no other call is a
way around that.

How to install
mdr add evanzhang008/open-walnut/walnut-weekly-health-trend@sha256:8d9e0f7fe92ea9caThe line at the top of this page pins the label git:20261004.ea58c50, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
