Metsuke (目つけ): AI-Assisted Development Task Manager

The name "Metsuke" comes from Japanese, often translated as "gaze" or "looking". However, in disciplines like martial arts (Budo), it signifies much more than just physical sight. Metsuke refers to the correct way of seeing – encompassing not just what you look at, but how you perceive the whole situation, maintain focus, anticipate movement, and understand intent without being fixated on minor details. It implies focused awareness and comprehensive perception.

This project aims to bring that spirit of focused awareness and clear perception to the collaboration between human developers and AI assistants. By providing a structured plan and context (PROJECT_PLAN.yaml), Metsuke helps both human and AI maintain focus on the overall goals and current tasks, improving understanding and leading to more intentional, effective development.

Why Metsuke? Enhancing Human-AI Collaboration 🤝

Working effectively with AI coding assistants requires clear communication and shared context. Metsuke is designed to work synergistically with AI coding assistants. Its structured approach using PROJECT_PLAN.yaml is particularly effective when the AI assistant also operates under a structured protocol (like RIPER-5) that emphasizes clear planning, execution, and review phases. This combination helps ensure predictable, reliable, and aligned collaboration. Metsuke bridges the gap by providing a structured framework based on a PROJECT_PLAN.yaml file, leading to significant benefits for both the human developer and the AI:

For the Human Developer: 🧑‍💻

  • Clarity & Overview: Get a clear, persistent view of project goals, context, and task status, reducing mental overhead.
  • Structured Planning: Define tasks, dependencies, and priorities explicitly.
  • Improved AI Guidance: Formulate requests to the AI with less ambiguity by referencing specific tasks and context from the plan.
  • Reliable Context: Avoid losing critical context buried in long chat histories.
  • Easier Verification: Quickly check if AI actions align with the planned tasks.
  • Interactive TUI Dashboard (metsuke tui): Gain real-time visibility into the project's status through an optional terminal interface. Visually track task completion progress, view status/priority breakdowns, explore dependencies, check suggested next steps, and monitor internal logs—all providing a convenient, high-level overview of the ongoing work and the AI's activity.

For the AI Assistant: 🤖

  • Structured Input: Receive project state, context, and task details in a predictable, machine-readable format.
  • Focused Tasks: Understand the specific goal of each request within the larger project plan.
  • Relevant Context: Access necessary background information directly from the plan file.
  • Improved Accuracy: Generate more relevant code and suggestions based on clear context and task definitions.
  • Reduced Deviation: Minimize guesswork and actions outside the scope of the agreed-upon plan.

Synergy & Performance: 👍

  • Shared Understanding: Creates a single source of truth for the project plan, minimizing miscommunication.
  • Predictable Collaboration: Makes the AI's behavior more aligned with the developer's intent.
  • Faster Progress: Reduces time spent on clarifying instructions or correcting off-track AI work.
  • Higher Quality: Promotes better outcomes through structured planning and focused execution.

By using Metsuke, the human-AI development team can collaborate more effectively, leading to faster, more robust, and more predictable results.

Example: Metsuke in Action ▶️

Imagine the following exchange without Metsuke:

User: Can you update the status bar to show the date? AI: Sure, I'll modify the StatusBar widget... (Proceeds to edit code that might not exist yet or is in the wrong place)

Now, contrast that with a Metsuke-guided interaction:

User: Please work on Task 16 (Enhance TUI StatusBar Display).

AI Assistant (using Metsuke): Okay, I see Task 16 is to enhance the StatusBar display with the date. Let me check the plan...

- id: 16
  title: Enhance TUI StatusBar Display
  # ...
  status: pending
  dependencies: [ 9 ]
- id: 9
  title: Structure TUI Code within Package
  # ...
  status: pending

AI Assistant: Task 16 depends on Task 9 (Structure TUI Code within Package), which is still pending. We need to complete Task 9 first by refactoring the TUI code into src/metsuke/tui/ before I can safely modify the StatusBar. Shall we proceed with Task 9 instead?

This example demonstrates how Metsuke provides:

  • Unambiguous Task Reference: The user clearly specifies Task 16.
  • Dependency Awareness: The AI checks PROJECT_PLAN.yaml and correctly identifies the prerequisite (Task 9).
  • Error Prevention: The AI avoids potentially harmful actions by respecting the planned dependencies.
  • Guided Workflow: The collaboration stays focused and follows the logical development order.

Features (Planned) 💡

  • YAML-based Planning: Define project context, goals, and tasks in a human-readable and machine-parseable format.
  • CLI Interface: View project info, list tasks, check status (including TUI via metsuke tui).
  • Library API: Programmatically load, validate, and potentially modify project plans.
  • Task Management: Track task status (pending, in_progress, done, etc.) and dependencies.
  • Context Awareness: Provides a central place for project context, easily accessible by both humans and AI.

Installation 📦

# Core CLI/Library (includes TUI)
pip install metsuke

# For development:
pip install -e .

Usage ⌨️

Command Line Interface (CLI):

# View project info
metsuke show-info

# List tasks
metsuke list-tasks

# Launch Terminal UI (Requires TUI dependencies)
metsuke tui

# Initialize a new project plan
metsuke init

# Repair YAML format issues in plan files
metsuke repair [file_path] [--dry-run]

# Update plan files to latest schema
metsuke update-plan

# (More commands to come)

Automatic YAML Repair: 🔧

Metsuke includes intelligent auto-repair functionality that helps maintain plan file integrity:

  • Automatic Background Repair: When loading plan files, Metsuke automatically detects and fixes common issues like:

    • Invalid task status values (corrected to 'pending', 'in_progress', 'Done', or 'blocked')
    • Invalid priority values (corrected to 'low', 'medium', or 'high')
    • Missing required fields (automatically added with sensible defaults)
    • Invalid data types (converted to correct types where possible)
    • Malformed dependency lists (cleaned and validated)
  • Manual Repair Command: Use metsuke repair to explicitly fix format issues:

    # Check what would be repaired (no changes made)
    metsuke repair --dry-run
    
    # Repair issues in the default plan file
    metsuke repair
    
    # Repair a specific file
    metsuke repair path/to/plan.yaml
  • Backup Creation: Before making repairs, Metsuke automatically creates timestamped backup files to prevent data loss.

This ensures that even if AI assistants accidentally introduce format issues when editing plan files, Metsuke can automatically correct them and continue working seamlessly.

Library Usage:

from metsuke import load_plan, PlanLoadingError, PlanValidationError

try:
    project_plan = load_plan("PROJECT_PLAN.yaml")
    print(f"Project Name: {project_plan.project.name}")
    for task in project_plan.tasks:
        print(f"- Task {task.id}: {task.title} ({task.status})")
except (PlanLoadingError, PlanValidationError) as e:
    print(f"Error loading plan: {e}")

Terminal User Interface (TUI) TUI

The Metsuke TUI provides a visual and interactive way to explore the PROJECT_PLAN.yaml content (or multiple plan files in a plans/ directory) directly in your terminal. It automatically monitors the plan file(s) for changes and updates the display in real-time.

Tutorial: Getting Started & AI Collaboration Workflow 🚀

This tutorial guides you through the entire process of setting up Metsuke for a new project and using it to collaborate effectively with an AI coding assistant.

1. Get the Code

First, clone the Metsuke repository (or your project's repository if Metsuke is added as a dependency later):

# Replace with the actual repository URL if different
git clone https://github.com/your_username/metsuke.git 
cd metsuke

2. Setup Environment & Install

It's highly recommended to use a Python virtual environment. (Requires Anaconda or Miniconda installed)

# python -m venv .venv # Old venv command
# source .venv/bin/activate # On Windows use `.venv\Scripts\activate` # Old venv command
conda create --name metsuke-env python=3.9 -y # Or choose another Python version >= 3.8
conda activate metsuke-env

Install Metsuke in editable mode (includes TUI dependencies):

pip install -e .

3. Initialize the Plan

Navigate to your project's root directory (if you cloned Metsuke, you are already there) and run:

metsuke init

This command:

  • Checks if a PROJECT_PLAN.yaml already exists (and exits if it does).
  • Attempts to detect your project's name and version from pyproject.toml (but uses placeholders in the generated file).
  • Creates a PROJECT_PLAN.yaml file containing:
    • Collaboration guidelines (comments at the top).
    • Placeholder project metadata (name: Your Project Name, version: '0.1.0').
    • A default project context section (you should edit this!).
    • A list of common starting tasks (you should customize these!).

Important: Open the newly created PROJECT_PLAN.yaml and customize the project, context, and initial tasks to match your actual project requirements.

4. Open in AI-Powered Editor

Open your project folder in an AI-powered code editor that supports direct interaction with an AI assistant, such as Cursor or VS Code with appropriate extensions.

5. Engage the AI Assistant

This is a crucial step for enabling effective collaboration. You need to explicitly instruct your AI assistant to use the PROJECT_PLAN.yaml file as the foundation for your work together.

Example prompts:

  • "Please read the PROJECT_PLAN.yaml file to understand the project goals, context, and current tasks."*
  • "Let's use PROJECT_PLAN.yaml as our single source of truth for planning and tasks."
  • "Refer to the tasks and context in PROJECT_PLAN.yaml for our development work going forward."
  • "I have a PROJECT_PLAN.yaml file defining our project. Please make sure you load and reference it."

Ensure the AI acknowledges that it has access to and will use the file. Some advanced AI integrations might detect and use the file automatically, but explicit instruction is the most reliable approach.

6. Collaborative Workflow Example

Here's how a typical interaction might look, assuming the AI assistant understands Metsuke and ideally follows a structured protocol (like RIPER-5):

You: "We need a new feature to detect circular dependencies in the plan file itself. Please add this as a new task to PROJECT_PLAN.yaml, priority 'medium'."

AI Assistant (using Metsuke): (Reads PROJECT_PLAN.yaml, finds last ID was 5) "Okay, I will add Task 6: Implement dependency cycle detection, priority 'medium', depending on Task 2 (Define core data models). Does this plan look good for the description: 'Plan: 1. Represent task dependencies as a graph. 2. Implement a graph traversal algorithm (e.g., Depth First Search). 3. Detect back edges during traversal which indicate cycles. 4. Report cycles found.'?"

You: "Yes, that plan looks good. Please add it."

AI Assistant: (Uses file editing tool) "Okay, I have added Task 6 to PROJECT_PLAN.yaml."

You: "Now, please implement Task 6."

AI Assistant: "Acknowledged. Entering EXECUTE mode for Task 6: Implement dependency cycle detection. Based on the plan, I will first represent dependencies as a graph..." (Proceeds with implementation, potentially involving further planning/review steps based on its protocol)

(...Implementation happens...)

AI Assistant: "Implementation for Task 6 is complete. Test Method: Create a test plan file PROJECT_PLAN_cycle.yaml with a known dependency cycle (e.g., Task A depends on B, Task B depends on A). Call the new function core.detect_cycles('PROJECT_PLAN_cycle.yaml') and assert that it returns True."

You: (You run the test) "Confirmed, the test passes."

You: "Please mark Task 6 as Done in the plan file."

AI Assistant: (Uses file editing tool) "Understood. Updating status for Task 6 to 'Done' in PROJECT_PLAN.yaml."

Outcome:

This workflow, facilitated by Metsuke and a cooperating AI, ensures:

  • Clarity: Both user and AI reference the same plan.
  • Traceability: Changes (like adding Task 6) are reflected in the plan.
  • Structure: Development follows defined tasks and dependencies.
  • Verification: The AI proposes a test method, and the user confirms completion.

This structured approach minimizes misunderstandings and keeps the development process focused and efficient.
