Artemis is the phone's hands. It drives the Pixel 8a screen from .13 over Tailscale using ADB wireless, so the Hub can do things no deep link allows.

The build spec is AGENTS.md. Follow the phases in section 11 in order.

Status

2 — Act primitives	✅ done — tap by text, type, scroll, back, home, launch
3 — Spotify recipe	not started
4 — Song radio	not started
5 — Maps recipe	not started
6 — Action API	not started
7 — Resilience	not started
8 — Documentation	not started

Build and test

Go is not installed system-wide on .13; use a one-off nix shell. Nothing is added to nixos-rebuild and no system module changes.

nix shell nixpkgs#go -c go build -o bin/artemis ./cmd/artemis
nix shell nixpkgs#go -c go vet ./...
nix shell nixpkgs#go -c go test ./...

Use

The phone address defaults to 100.101.49.17. Override with ARTEMIS_PHONE, pin a serial with ARTEMIS_ADB_SERIAL, or point at a different adb with ARTEMIS_ADB.

./bin/artemis connect          # scan for the wireless-debugging port, then connect
./bin/artemis devices
./bin/artemis dump             # text nodes and bounds
./bin/artemis launch com.spotify.music
./bin/artemis tap "Search"     # find by text, tap its centre (FR-4)
./bin/artemis type "Rolling Stones Honky Tonk"
./bin/artemis scroll down
./bin/artemis back
./bin/artemis home
./bin/artemis demo             # Phase 2 DoD: launch an app, tap a named element

Rules that the code enforces

Find by text, never fixed coordinates. tap resolves a text match to bounds and taps the centre.
Never tap blindly. A missing or disabled element is a loud failure, not a guessed coordinate.
Wake first. Every acting command wakes the screen (FR-7).
Bound every command. No adb call runs without a timeout (FR-11).
