Overview

This skill provides patterns and ready-to-run scripts for CRUD operations on Google Drive using the Drive API v3.

Supporting files:

• scripts/drive_client.py — shared auth factory (imported by all scripts)
• assets/service_account_template.json — template for your service account JSON
• references/mime_types.md — MIME type quick reference
• references/error_codes.md — HTTP error codes + retry patterns

Quick Start

1. Install dependencies

pip install google-api-python-client google-auth google-auth-httplib2

2. Set credentials

# Read-only (public files):
export GOOGLE_API_KEY="your_api_key_here"

# Read + write (service account):
export GOOGLE_SERVICE_ACCOUNT_JSON="/path/to/service_account.json"

See assets/service_account_template.json for the expected JSON structure.

3. Resolve SKILL_SCRIPTS (see top of this file), then run scripts

Script Commands

List files in a folder

# Table output (default):
python "$SKILL_SCRIPTS/list_files.py" --folder-id FOLDER_ID

# JSON output:
python "$SKILL_SCRIPTS/list_files.py" --folder-id FOLDER_ID --json

Download a file

# Save to specific path:
python "$SKILL_SCRIPTS/download_file.py" --file-id FILE_ID --dest ./downloads/report.pdf

# Save to directory (auto filename from Drive):
python "$SKILL_SCRIPTS/download_file.py" --file-id FILE_ID --dest ./downloads/

Create a folder

# In Drive root:
python "$SKILL_SCRIPTS/create_folder.py" --name "My New Folder"

# Inside a specific parent folder:
python "$SKILL_SCRIPTS/create_folder.py" --name "Subfolder" --parent-id PARENT_FOLDER_ID

Upload a file

# Basic upload (MIME type auto-detected):
python "$SKILL_SCRIPTS/upload_file.py" --src ./report.pdf --parent-id FOLDER_ID

# Custom name on Drive:
python "$SKILL_SCRIPTS/upload_file.py" --src ./report.pdf --name "Q1-Report.pdf" --parent-id FOLDER_ID

# Upload and make publicly readable immediately:
python "$SKILL_SCRIPTS/upload_file.py" --src ./photo.png --parent-id FOLDER_ID --make-public

Update a file

# Rename:
python "$SKILL_SCRIPTS/update_file.py" --file-id FILE_ID --name "New Name.pdf"

# Move to a different folder:
python "$SKILL_SCRIPTS/update_file.py" --file-id FILE_ID --move-to NEW_PARENT_ID --old-parent OLD_PARENT_ID

python "$SKILL_SCRIPTS/update_file.py" --file-id FILE_ID --src ./updated_report.pdf

# Rename + replace content:
python "$SKILL_SCRIPTS/update_file.py" --file-id FILE_ID --name "v2.pdf" --src ./v2.pdf

Delete or trash a file

# Move to trash (safe, recoverable):
python "$SKILL_SCRIPTS/delete_file.py" --file-id FILE_ID

# Permanently delete (prompts for confirmation):
python "$SKILL_SCRIPTS/delete_file.py" --file-id FILE_ID --permanent

# Permanently delete (non-interactive):
python "$SKILL_SCRIPTS/delete_file.py" --file-id FILE_ID --permanent --yes

Manage permissions

# Make file publicly readable (anyone with link):
python "$SKILL_SCRIPTS/set_permissions.py" --file-id FILE_ID --public

# Share with a user as writer:
python "$SKILL_SCRIPTS/set_permissions.py" --file-id FILE_ID --email user@example.com --role writer

# Share with a user as reader:
python "$SKILL_SCRIPTS/set_permissions.py" --file-id FILE_ID --email user@example.com --role reader

# List current permissions (returns JSON):
python "$SKILL_SCRIPTS/set_permissions.py" --file-id FILE_ID --list

# Remove a specific permission:
python "$SKILL_SCRIPTS/set_permissions.py" --file-id FILE_ID --remove PERMISSION_ID

Auth Setup

Option A — API Key (read-only public files)

Use when the file/folder is shared as "Anyone with the link" and you only need to read.

from googleapiclient.discovery import build

API_KEY = os.environ["GOOGLE_API_KEY"]
drive = build("drive", "v3", developerKey=API_KEY)

Option B — Service Account (read + write on shared/public drives)

Use when you need to create, modify, or delete files.

from google.oauth2 import service_account
from googleapiclient.discovery import build
import os

SCOPES = ["https://www.googleapis.com/auth/drive"]
creds = service_account.Credentials.from_service_account_file(
    os.environ["GOOGLE_SERVICE_ACCOUNT_JSON"], scopes=SCOPES
)
drive = build("drive", "v3", credentials=creds)

Copy assets/service_account_template.json to see the expected structure. Store the real file outside the repo and never commit it. Add service_account.json to .gitignore.

File & Folder ID

Every Drive resource has a unique fileId. Extract it from the share URL:

https://drive.google.com/drive/folders/FOLDER_ID_HERE
https://drive.google.com/file/d/FILE_ID_HERE/view

CRUD Operations

List Files in a Public Folder

def list_files(drive, folder_id: str) -> list[dict]:
    results = []
    page_token = None
    while True:
        resp = drive.files().list(
            q=f"'{folder_id}' in parents and trashed=false",
            fields="nextPageToken, files(id, name, mimeType, size, modifiedTime)",
            pageToken=page_token,
            supportsAllDrives=True,
            includeItemsFromAllDrives=True,
        ).execute()
        results.extend(resp.get("files", []))
        page_token = resp.get("nextPageToken")
        if not page_token:
            break
    return results

Download a Public File

import io
from googleapiclient.http import MediaIoBaseDownload

def download_file(drive, file_id: str, dest_path: str) -> None:
    request = drive.files().get_media(fileId=file_id, supportsAllDrives=True)
    with open(dest_path, "wb") as fh:
        downloader = MediaIoBaseDownload(fh, request)
        done = False
        while not done:
            _, done = downloader.next_chunk()

Create a Folder

def create_folder(drive, name: str, parent_id: str | None = None) -> str:
    metadata = {
        "name": name,
        "mimeType": "application/vnd.google-apps.folder",
    }
    if parent_id:
        metadata["parents"] = [parent_id]
    folder = drive.files().create(
        body=metadata,
        fields="id",
        supportsAllDrives=True,
    ).execute()
    return folder["id"]

Upload / Create a File

from googleapiclient.http import MediaFileUpload

def upload_file(
    drive,
    local_path: str,
    name: str,
    parent_id: str | None = None,
    mime_type: str = "application/octet-stream",
) -> str:
    metadata = {"name": name}
    if parent_id:
        metadata["parents"] = [parent_id]
    media = MediaFileUpload(local_path, mimetype=mime_type, resumable=True)
    file = drive.files().create(
        body=metadata,
        media_body=media,
        fields="id",
        supportsAllDrives=True,
    ).execute()
    return file["id"]

Upload from In-Memory Bytes

from googleapiclient.http import MediaIoBaseUpload

def upload_bytes(
    drive,
    data: bytes,
    name: str,
    parent_id: str | None = None,
    mime_type: str = "application/octet-stream",
) -> str:
    metadata = {"name": name}
    if parent_id:
        metadata["parents"] = [parent_id]
    media = MediaIoBaseUpload(io.BytesIO(data), mimetype=mime_type, resumable=True)
    file = drive.files().create(
        body=metadata,
        media_body=media,
        fields="id",
        supportsAllDrives=True,
    ).execute()
    return file["id"]

Update File Metadata (rename, move)

def rename_file(drive, file_id: str, new_name: str) -> None:
    drive.files().update(
        fileId=file_id,
        body={"name": new_name},
        supportsAllDrives=True,
    ).execute()

def move_file(drive, file_id: str, new_parent_id: str, old_parent_id: str) -> None:
    drive.files().update(
        fileId=file_id,
        addParents=new_parent_id,
        removeParents=old_parent_id,
        fields="id, parents",
        supportsAllDrives=True,
    ).execute()

Update File Content

def update_file_content(
    drive,
    file_id: str,
    local_path: str,
    mime_type: str = "application/octet-stream",
) -> None:
    media = MediaFileUpload(local_path, mimetype=mime_type, resumable=True)
    drive.files().update(
        fileId=file_id,
        media_body=media,
        supportsAllDrives=True,
    ).execute()

Delete a File or Folder

def delete_file(drive, file_id: str) -> None:
    drive.files().delete(fileId=file_id, supportsAllDrives=True).execute()

Deleting a folder also deletes all its children permanently. Prefer trashing: ``python drive.files().update(fileId=file_id, body={"trashed": True}).execute() ``

Set Permissions (Make Public)

To make a file publicly readable (anyone with the link):

def make_public(drive, file_id: str) -> None:
    drive.permissions().create(
        fileId=file_id,
        body={"role": "reader", "type": "anyone"},
        supportsAllDrives=True,
    ).execute()

To grant write access to a specific user:

def share_with_user(drive, file_id: str, email: str, role: str = "writer") -> None:
    # role: "reader", "commenter", "writer", "fileOrganizer", "organizer", "owner"
    drive.permissions().create(
        fileId=file_id,
        body={"role": role, "type": "user", "emailAddress": email},
        sendNotificationEmail=False,
        supportsAllDrives=True,
    ).execute()

Common MIME Types

Error Handling

from googleapiclient.errors import HttpError

def safe_delete(drive, file_id: str) -> bool:
    try:
        drive.files().delete(fileId=file_id, supportsAllDrives=True).execute()
        return True
    except HttpError as e:
        if e.resp.status == 404:
            return False  # already gone
        raise

Common HTTP status codes:

• 400 — bad request (check field names, MIME types)
• 403 — permission denied (check auth scope or file sharing settings)
• 404 — file not found (check fileId, supportsAllDrives)
• 429 — rate limited (back off and retry)

Required Python Packages

google-api-python-client>=2.100.0
google-auth>=2.23.0
google-auth-httplib2>=0.1.1

Install:

pip install google-api-python-client google-auth google-auth-httplib2

Security Notes

• Never hardcode API keys or service account credentials in source code. Use environment variables or secret managers.
• Restrict API key to the Drive API scope in the Google Cloud Console.
• Service account credentials (service_account.json) must be in .gitignore.
• When sharing files, prefer time-limited access tokens over permanent public links where possible.
• "type": "anyone" with "role": "writer" on a production folder is dangerous — audit permissions regularly.
