Google Drive Upload

Upload files directly to Google Drive via a deployed Google Apps Script web app.

Completely free — unlimited uploads, no restrictions.

Environment note: This skill works in both Claude Code and Cowork. The only difference is how the config file is read in Step 1 — Claude Code reads it directly, Cowork uses osascript.

---

Step 1: Read the config

The config lives on the Mac at ~/.cowork-gdrive-config.json.

In Claude Code (direct file system access):

CONFIG=$(cat ~/.cowork-gdrive-config.json 2>/dev/null || echo "NOT_CONFIGURED")

In Cowork (VM — needs osascript to reach the Mac home):

CONFIG=$(osascript -e 'do shell script "cat ~/.cowork-gdrive-config.json 2>/dev/null || echo NOT_CONFIGURED"')

Then parse it safely in Python — never log or print the raw config string:

python3 -c "
import json, sys
raw = '''$CONFIG'''
if raw.strip() == 'NOT_CONFIGURED':
    print('STATUS:NOT_CONFIGURED')
    sys.exit(0)
try:
    cfg = json.loads(raw)
    print('STATUS:OK')
    print(f'URL:{cfg[\"url\"]}')
except Exception as e:
    print(f'STATUS:PARSE_ERROR:{e}')
"

• If STATUS:NOT_CONFIGURED → tell the user: "The Google Drive connection isn't set up yet. Please follow the setup instructions at https://msapps.mobi/plugins to configure your Apps Script URL." Stop here.
• If STATUS:PARSE_ERROR → tell the user the config file is malformed and ask them to check ~/.cowork-gdrive-config.json.
• If STATUS:OK → extract URL from output. Continue.

Step 2: Identify the file

Check common output locations — use the file the user specified, or find the most recent:

ls -lt "$HOME/Documents/Claude/"*.* 2>/dev/null | head -5
ls -lt /sessions/*/mnt/outputs/ 2>/dev/null | head -5
ls -lt /sessions/*/mnt/Claude/ 2>/dev/null | head -5

Ask the user to confirm which file to upload if it's not obvious.

---

Step 3: Upload the file

Always use the temp file approach — it handles filenames with spaces, Hebrew characters, and special chars safely:

FILE="<absolute-path-to-file>"
FILENAME=$(basename "$FILE")
B64=$(base64 "$FILE" | tr -d '\n')
MIME=$(file --mime-type -b "$FILE")
GDRIVE_URL="<URL from Step 1>"

cat > /tmp/gdrive_payload.json << JSONEOF
{
  "fileName": "$FILENAME",
  "content": "$B64",
  "mimeType": "$MIME",
  "folderPath": "Claude Uploads"
}
JSONEOF

RESPONSE=$(curl -s -L --fail --max-time 60 \
  -H "Content-Type: application/json" \
  -d @/tmp/gdrive_payload.json \
  "$GDRIVE_URL")
CURL_EXIT=$?
rm -f /tmp/gdrive_payload.json

echo "CURL_EXIT:$CURL_EXIT"
echo "RESPONSE:$RESPONSE"

Handle the response:

• If CURL_EXIT is non-zero → upload failed (network error, timeout, bad URL). Tell the user.
• If CURL_EXIT is 0 → parse RESPONSE as JSON and check "success": true.
  • If success: false → report the error message from "error" field.
  • If success: true → proceed to Step 4.

---

Step 4: Report to user

Tell the user:

• File uploaded successfully
• Google Drive link (from "fileUrl" in the API response)

Example:

"Uploaded report.pdf to Google Drive → View file"

---

Folder targeting

The POST body supports:

• folderPath: "Folder/Subfolder" — creates folders if needed
• folderId: "1abc..." — specific folder ID
• Default: saves to "Claude Uploads" folder in My Drive
• Add "replaceExisting": true to overwrite a file with the same name

---

Notes

• File size limit: ~50MB
• Config at ~/.cowork-gdrive-config.json
• No upload limits — completely free
