AI Deployment Directory Summary Script

I'm looking for a Python script that uses a local, CPU-based AI model (like those from the transformers library) to read through a directory of various code and configuration files (SQL, YAML, XML, Python, etc.) and generate a high-level summary.

Requirements:
- Read all files in a given directory.
- Generate a single, consolidated high-level summary for all files.
- Summaries should include 2-3 important lines per file, e.g., "New stored procedure 'zxx' for data loading."

Ideal Skills and Experience:
- Proficiency in Python
- Experience with AI/ML models, especially transformers
- Familiarity with file I/O and directory traversal in Python
- Ability to generate concise, meaningful summaries from code
