📁 1. Initial Project Structure

Create a new directory in your Linux system named antigravity-tkinter-todo and add the following blank files. The final structure developed by the agent will look like this:

Plaintext

antigravity-tkinter-todo/
├── implementation_plan.md   # The blueprint file the agent will read and follow
├── main.py                  # The main entry point of the Python application
├── database.py              # Logic for saving tasks (JSON data persistence)
└── requirements.txt         # Project dependencies (Tkinter is built-in, but good for extra packages)

📝 2. Blueprint Configuration: implementation_plan.md

Create this file in the root directory. Google Antigravity agents automatically look for this file to understand the architecture requirements before writing the code. Copy and paste the following content:

# Implementation Plan: ToDo Application in Python Tkinter

## Objective
Build a modern desktop task management application (ToDo App) utilizing Python and its native graphical library, Tkinter.

## Functional Requirements
1. **Add Tasks:** Input text field with a dedicated submission button.
2. **Task List Display:** A central list area with a scrollbar to view all current items.
3. **Task Completion:** Ability to toggle or strike-through completed tasks.
4. **Delete Tasks:** Actions to remove individual tasks or clear the entire list.
5. **Data Persistence:** Automatically serialize the task list into a local `tasks.json` file upon closing and reload it on startup.

## Guidelines for the Antigravity Agent
- Use a clean, modern UI layout (padded elements, soft pastel background colors).
- Execute the script in the local Linux terminal to catch syntax or operational errors.
- Launch the GUI on the local display to validate the interface layout and responsive scaling.

💻 3. Boilerplate Code: main.py

To give the agent an exact starting point, you can pre-populate main.py with this basic application frame. The Antigravity agent will pick up this file and inject the requested features:

Python

import tkinter as tk
from tkinter import messagebox
import json
import os

class TodoApp:
    def __init__(self, root):
        self.root = root
        self.root.title("Antigravity ToDo - Tkinter")
        self.root.geometry("400x500")
        self.root.configure(bg="#f3f4f6") # Modern light grey background
        
        # UI Setup
        self.setup_ui()
        
    def setup_ui(self):
        # Header Title
        title_label = tk.Label(
            self.root, 
            text="My ToDo List", 
            font=("Arial", 16, "bold"), 
            bg="#f3f4f6", 
            fg="#1f2937"
        )
        title_label.pack(pady=10)
        
        # TODO: The Antigravity Agent will generate the input fields, listbox, and task logic below

if __name__ == "__main__":
    root = tk.Tk()
    app = TodoApp(root)
    root.mainloop()

🚀 4. How to Trigger the Task in Google Antigravity

1. Open your Google Antigravity IDE.

2. Navigate to File -> Open Folder and select your antigravity-tkinter-todo folder.

3. Open the Agent Chat sidebar panel on the right side of the screen and send the following prompt:

Prompt: "Read the implementation_plan.md file in the workspace root. Complete the full application logic inside main.py for this Tkinter ToDo app. Ensure you hook up the auto-saving mechanism to tasks.json and launch the application in the local Linux terminal to test that the graphical interface renders properly."

What the agent will do autonomously:

• Parse your Markdown plan and verify the structural rules.

• Code the implementation mechanisms for tasks updates, removals, and visual strike-through tags.

• Connect the read/write sequences to handle tasks.json.

• Spin up a local bash execution context running python3 main.py. The working window of your newly created ToDo application will pop right open onto your Linux desktop environment!

I have completed building the ToDo Application! Here is a summary of the implementation and verification:

1. **Implemented ToDo App**: Created the main file [todo_app.py](file:///home/mhcrnl/Documents/antigravity/kind-pythagoras/todo_app.py) with a decoupled `TodoModel`, custom scrollable container, flat modern pastel styles, filter tabs, double-click shortcuts, and automatic saving/loading to `tasks.json`.

2. **Created Unit Tests**: Created [test_todo_app.py](file:///home/mhcrnl/Documents/antigravity/kind-pythagoras/test_todo_app.py) testing all core data model features. Checked that all 8 tests pass successfully.

3. **Launched GUI**: Successfully started the application on your local display. It is currently running in the background as task `task-44`.

You can view the detailed changes, test results, and instructions in the [walkthrough.md](file:///home/mhcrnl/.gemini/antigravity/brain/38fee897-6816-4775-b9d5-53d6f4073b35/walkthrough.md) file. Enjoy organizing your tasks!

The ToDo application GUI process (`task-44`) has finished running successfully. All tasks and changes are persisted in the local `tasks.json` file in your workspace.

If you would like to run it again, you can execute the following in your terminal:

```bash

python3 todo_app.py

```

Let me know if you would like to add any further features (such as task categories, priority levels, or due dates)!
