Antigravity: agent unable to see command output

Problem

After the Antigravity agent runs a command the command executes fine and the output is visible in the UI, but the agent does not see the output.

From Reddit:
Terminal escape codes break Antigravity. Create a .bashrc branch for Antigravity that disables fancy terminal features:

if [[ -n "$ANTIGRAVITY_AGENT" ]]; then
    export PS1='$ '
    unset PROMPT_COMMAND
    return
fi
