Put Wingman in read-only mode
What it does
Telling Wingman "turn on read only mode" restricts it to GET endpoints, so it can still answer questions and review how a workspace is put together but cannot change anything in it.
Before this
You could already ask Wingman to explain or review a workspace, but nothing separated looking from acting — "have a look at this" and "go and change it" carried the same permissions.
Why it matters
Asking the assistant to look at your workspace should not carry a risk that it edits something while it is in there.
How it works
The switch is a sentence rather than a setting: say "turn on read only mode" to restrict it, and "disable read-only mode" to hand the write endpoints back.
It is a capability limit rather than a different assistant. Wingman keeps its full view of the workspace, so answers, reviews and recommendations are unchanged — only the endpoints that would modify something are withheld.
