ML Agent Framework Multi-Provider - Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Build a multi-provider ML framework that replicates ml-intern functionality with support for Claude, OpenAI, DeepSeek, and Mistral, enabling automated ML workflows (dataset collection → training → deployment).

Architecture: A modular Python framework with pluggable LLM providers, workflow engine, and CLI interface. Core abstracts provider differences; workflows compose reusable steps; plugins enable extensibility.

Tech Stack: Python 3.11+, Typer (CLI), Pydantic (config), Structlog (logging), Hugging Face Transformers, pytest

Global Constraints

Python minimum: 3.11
License: Apache 2.0
Providers in v1.0: Claude, OpenAI, DeepSeek, Mistral (others via plugins)
Output directory: ~/ml-agent (respects XDG paths)
Config format: YAML + .env
Logging: Structured JSON logs to ~/.ml-agent/logs/
Test coverage minimum: 80% excluding examples
Public release: p7dotorg organization on GitHub

Phase 1: Foundation & Core Infrastructure

Task 1: Project Setup & Dependencies

Files:

Create: pyproject.toml
Create: src/ml_agent/__init__.py
Create: src/ml_agent/core/__init__.py
Create: .github/workflows/test.yml

Interfaces:

Produces: Package structure ready for imports (from ml_agent.core import ...)
Step 1: Create pyproject.toml with all dependencies

[tool.pytest.ini_options]
testpaths = ["tests"]
python_files = "test_*.py"
python_classes = "Test*"
python_functions = "test_*"

Step 2: Create directory structure

mkdir -p src/ml_agent/{core,providers,auth,workflows,utils,plugins,cli}
mkdir -p tests/{unit,integration,fixtures}
mkdir -p examples/{latex-explainer,simple-workflow}
mkdir -p docs

Step 3: Create init.py files

"""ML Agent Framework - Multi-provider ML workflow automation."""

__version__ = "1.0.0"
__author__ = "p7dotorg"

# src/ml_agent/core/__init__.py
"""Core components of ML Agent Framework."""

Step 4: Create GitHub Actions test workflow

# .github/workflows/test.yml
name: Tests

on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.11", "3.12"]
    
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v4
        with:
          python-version: ${{ matrix.python-version }}
      
      - name: Install dependencies
        run: |
          python -m pip install -e ".[dev]"
      
      - name: Run tests with coverage
        run: |
          pytest --cov=src/ml_agent --cov-report=xml tests/
      
      - name: Upload coverage
        uses: codecov/codecov-action@v3

Step 5: Create .gitignore

__pycache__/
*.py[cod]
*$py.class
.env
.env.local
auth.json
*.egg-info/
dist/
build/
.pytest_cache/
.mypy_cache/

agent = MLAgent(
    provider="claude",
    workflow="arxiv-dataset",
    workflow_config={"output_file": "dataset.jsonl"}
)

Workflow

Base class for workflows.

from ml_agent.workflows.base import Workflow

class MyWorkflow(Workflow):
    name = "my-workflow"
    
    async def execute(self):
        step = WorkflowStep(...)
        await self.run_step(step)

Providers

claude - Anthropic Claude
openai - OpenAI GPT
deepseek - DeepSeek
mistral - Mistral AI

Workflows

arxiv-dataset - Collect dataset from arXiv
fine-tune - Fine-tune model
deploy-hub - Deploy to Hugging Face Hub


- [ ] **Step 3: Create PLUGINS.md**

```markdown
# Plugin System

## Creating a Provider Plugin

```python
from ml_agent.plugins.base import ProviderPlugin
from ml_agent.providers.base import BaseProvider

class MyProvider(BaseProvider):
    name = "myprovider"
    
    async def complete(self, messages, **kwargs):

        pass
    
    def get_provider_class(self):
        return MyProvider

Place in ~/.ml-agent/plugins/my_provider.py


- [ ] **Step 4: Update README.md**

```markdown
# ML Agent Framework

Multi-provider ML workflow automation framework supporting Claude, OpenAI, DeepSeek, and Mistral.

## Installation

```bash
pip install ml-agent
