Back up all Cowork-related folders to Google Drive.

Session path note: Cowork VM session names change every run. Do NOT hardcode a session name like loving-gracious-allen. Instead, discover the active session dynamically (Step 1).

---

Step 1: Discover session path and read GDrive config

import json, os, glob, sys

# Discover the active session that has the credentials file
candidates = glob.glob('/sessions/*/mnt/Claude/credentials/cowork-gdrive-config.json')
if not candidates:
    print('STATUS:NOT_FOUND')
    sys.exit(1)

cfg_path = candidates[0]
session_mnt = cfg_path.replace('/Claude/credentials/cowork-gdrive-config.json', '')  # e.g. /sessions/abc-xyz/mnt

with open(cfg_path) as f:
    cfg = json.load(f)

print('STATUS:OK')
print(f'SESSION_MNT:{session_mnt}')
print(f'URL:{cfg["url"]}')
print(f'APIKEY:{cfg["apiKey"]}')

If STATUS is NOT_FOUND, stop and report:

Config file missing. On your Mac, run once: cp ~/.cowork-gdrive-config.json ~/Documents/Claude/credentials/cowork-gdrive-config.json

---

Step 2: Flush debug screenshots

Delete temporary debug screenshots from the Claude docs folder (top level only).

Why Desktop Commander? The VM filesystem mount is read-only for deletes — use Desktop Commander to run the delete natively on the Mac.

Use mcp__Desktop_Commander__start_process with:

command: find ~/Documents/Claude -maxdepth 1 -type f \( -name '*.png' -o -name '*.jpg' -o -name '*.jpeg' -o -name '*.gif' \) -delete && echo 'Screenshots flushed'
timeout_ms: 15000

(Failure is non-fatal — continue anyway.)

---

Step 3: Build backup zips into /tmp/cowork-backup/

All zips must exclude: */node_modules/*, */.git/*, */.next/*, *.pyc, *.png, *.jpg, *.jpeg, *.gif, */package-lock.json

Use SESSION_MNT from Step 1 for all paths.
