Check the advisor install
Two modes. Default is free (no advisor call). --live makes one real,
paid advisor call to prove the whole pipeline actually works, not just
that it looks configured. Only add --live if the user explicitly asks
for a full/live/real check - never add it "to be thorough" on your own.
Find the script
This skill's own base directory, shown above when it loaded, is
<plugin-root>/skills/doctor. Drop the trailing /skills/doctor to get
<plugin-root> - the script is at <plugin-root>/server/doctor.py.
Run it
Free check (default):
python3 <plugin-root>/server/doctor.py
Full check (only if the user explicitly asked - real cost):
python3 <plugin-root>/server/doctor.py --live
Report the result
The output is already pass/fail per line - show it plainly, don't summarize a FAIL away. If a line names the fix (e.g. "run /advisor-model "), say so; otherwise just report what's broken.
