    "description": "Captures a connected Clawdmeter board's screen as a PNG over USB serial, with the bundled screenshot.py (the firmware's `screenshot` framebuffer dump, decoded). Use when asked to screenshot a board or the device, to check UI on real hardware, or to attach device output to a PR."
}

Capturing device screenshots

python3 ${CLAUDE_SKILL_DIR}/scripts/screenshot.py /path/out.png

Then Read the PNG. It's sized to the panel (480×480 on the AMOLED-2.16) and takes about 2 s. Write it outside the repo unless it belongs in the PR.

Port: the only /dev/ttyACM* or /dev/cu.usbmodem* attached; pass --port when there are several. Close any pio device monitor first, it holds the port. Opening the port doesn't reset the board.
pyserial missing: run it with ~/.platformio/penv/bin/python.
C6 boards can't be captured: no PSRAM for the snapshot, so the script stops with a message. Eyeball those on the panel, or check the same UI in the simulator (verifying-firmware-ui skill).
A specific state: force it over serial first (clawd show, clawd attention, … via the flashing-and-probing-boards skill), then capture.
