It seems that `firefox` is not installed. We can use `chromium` or another web browser available on this system. Let's use `chromium` to open the web page.
{"command":"chromium index.html","timeout":60}/bin/bash: line 1: chromium: command not found Command exited with code 127
It appears that neither `firefox` nor `chromium` are installed on this system. Instead, we can open the HTML file in the default web browser. Let's use the `xdg-open` command to open the file in the default browser.

It seems there is no default web browser or the `xdg-open` command is not available. Given this, we can still proceed by directly opening the file in the web browser of your choice after this interaction.

TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION
Blank white page throughout; JS syntax error prevented any piano keyboard from rendering.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
