Step 8 of the Google Workspace connector prompt told Claude to call
`gws drive files list` + `gws chat spaces list` and parse counts
out of the JSON response. In practice Claude improvised a
`python3 -c 'f"… {len(d.get(\"files\",[]))}…"'` snippet that
fails in two ways: f-string expressions reject backslashes pre-3.12
(SyntaxError), and gws can emit a banner ahead of the JSON body
(JSONDecodeError on `json.load(sys.stdin)`).
Treat exit code 0 from each gws call as success, drop the
`<N> drive file(s), <M> chat space(s) visible` counts (consistent
with the Step 0 precheck), and explicitly warn off the two
anti-patterns. Summary-grep prefix `✅ Google Workspace ready —` is
preserved so the install-summary still picks the line up.
