Answer questions about where the user has been, from the visits Walnut on the iPhone records once the user turns Places on: "where was I on Tuesday", "how long was I at the office this week", "when did I get home", "have I been to the gym lately". Use when the user asks about places they went or time spent at one.
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
# Places
Walnut on the iPhone records the places the user visits only after they turn
Places on, and only from then on. There is no history from before that, and
nothing to import. iOS records a visit when the user stays somewhere for a
while, so a quick stop may be missing, and there is never a route between visits.
## 1. Read the visits
```
walnut tools call places_visits '{"last_days":7}'
```
Other windows: `{"from":"2026-10-01","to":"2026-10-03"}` (dates are inclusive),
or one place: `{"last_days":30,"place":"gym"}`.
The answer holds `visits` (oldest first) and `places` (the same visits grouped by
place, longest total first). Per visit:
- `arrival`, `departure`: local time with the offset of where the visit was.
- `durationMin`: the length. Null when either end is unknown.
- `status`: `ended`; `ongoing` (still there, the length counts to now);
`departure_unknown` (iOS never reported leaving, or Places stopped recording
first: say the length is unknown, never guess it).
- `arrivalUnknown`: iOS saw only the departure.
- `name`, `address`: what the phone looked up. Null when it could not: describe
the visit by time, never by coordinates.

How to install
mdr add evanzhang008/open-walnut/walnut-places@sha256:23160b73fd9e42c5The line at the top of this page pins the label git:20261006.d01eeb3, 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.
