Prerequisites

```bash

# Python dependencies

pip install scikit-learn pandas numpy

pip install transformers peft datasets

pip install chromadb sentence-transformers

pip install mlflow optuna

pip install openai anthropic

pip install fastapi uvicorn

# Optional: GPU support

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

```

Environment Setup

```

AI Engineer - OpenAI Integration

```python

from ai_engineer_skill.scripts.integrate_openai import OpenAIIntegration, OpenAIConfig

config = OpenAIConfig(api_key=os.getenv("OPENAI_API_KEY"))

integration = OpenAIIntegration(config)

messages = [{"role": "user", "content": "Hello!"}]

response = integration.chat_completion(messages)

print(response['content'])

```

LLM Architect - Model Benchmarking

```python

from llm_architect_skill.scripts.benchmark_models import ModelBenchmarker

benchmarker = ModelBenchmarker(models)

benchmarker.benchmark_task("summarization", task_func, test_data)

best = benchmarker.get_best_model_for_task("summarization")

```

ML Engineer - Training Pipeline

```python

from ml_engineer_skill.scripts.train_sklearn import MLModelTrainer, ModelConfig

trainer = MLModelTrainer(ModelConfig())

X_train, X_test = trainer.preprocess_features(X_train, X_test)

trainer.train_model(X_train, y_train)

metrics = trainer.evaluate_model(X_test, y_test)

```

MLOps - MLflow Tracking

```python

from mlops_engineer_skill.scripts.track_mlflow import MLflowTracker

tracker = MLflowTracker(experiment_name="my_experiment")

run_id = tracker.start_run("run_1")

tracker.log_params({"lr": 0.01, "epochs": 10})

tracker.log_metrics({"accuracy": 0.95})

tracker.log_model(model, "my_model")

tracker.end_run()

```

Error Handling

All scripts include:

• Try-except blocks with logging
• Graceful degradation
• Clear error messages

Configuration

• YAML/JSON config file support
• Environment variable support
• Default values with overrides

Logging

• Structured logging
• Multiple log levels
• Timestamp and context

Documentation

• Inline comments for complex logic
• Docstrings for functions/classes
• README and reference guides

Each skill follows consistent patterns:

1. Create scripts/ directory for executable code
2. Create references/ directory for documentation
3. Use dataclasses for configuration
4. Include error handling and logging
5. Provide example usage in main() function

Production-ready educational code. Adapt to your needs.

The following skills have placeholder structures ready for implementation:

• machine-learning-engineer-skill
• data-scientist-skill
• data-analyst-skill
• prompt-engineer-skill
• devops-incident-responder-skill

Follow the existing patterns to implement these skills.
