// key findings
⚠️
Tool annotations don’t match behaviour
10 read-only tools perform write/delete/exec — gcal_list_calendars (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 })); gcal_list_events (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 })); gcal_get_event (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 }))
⚠️
Tool descriptions don’t match what handlers do
10 tools describe read intent but their handlers mutate — gcal_list_calendars (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 })); gcal_list_events (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 })); gcal_get_event (line 86: writeFile(path, JSON.stringify(token, null, 2), { mode: 0o600 }))
