The skill described a SOM overlay burned into the screenshot, a driver-side
`capture` tool, and manual symlinking of the cua-driver skill pack; users
who read the driver's own docs then called raw MCP tools (`capture`,
bare `element_index`) and hit "no reviewed risk classification" and
`snapshot_id_required`. State plainly that `computer_use(action=...)` is a
wrapper vocabulary the driver never sees, that `element=N` is translated to
the snapshot token, what a `stale` refusal means, how text-only models get
vision (auxiliary.vision routing / mode=ax), and the Windows WindowsApps
doctor failure. `cua-driver skills install` links into ~/.hermes/skills now.
