ARD reserves text/markdown for agent skills, and Lighthouse warned on
the llms.txt entry. skills/setup-bios/SKILL.md holds the steps that set
up a device with the fewest files, and the manifest lists it as a skill.
device_setup_command built a shell command from the agent's values: a
typographic quote ends a PowerShell string, and a path starting with -
reads as an option. Such values are refused, the options are written
attached to their values, and platform must be a setup name.
llms.txt and an ARD manifest name the pages and the JSON API, and lead
an agent setting up a device to --for-games --required-only. Every page
registers four read-only WebMCP tools: the setup command, a hash lookup,
an emulator's files and the site search.
