Agentic Patterns

Code samples from learning how to create and orchestrate AI agents from Agentic Design Patterns.

This project contains the code samples from the book (modified by me and various coding agents!) with a key addition: a shared common library for standardized logging across all sub-projects.

Project Structure

• Numbered Folders (1-prompt-chaining, etc.): Each folder is a standalone uv project corresponding to a chapter or pattern from the book.
• common/: A shared Python library that provides common utilities, primarily a sophisticated logging setup powered by the rich library.

Getting Started

1. Install Prerequisites:

   • Install Python 3.13+. (asdf install python 3.13.5)
   • Install uv. (curl -LsSf https://astral.sh/uv/install.sh | sh)

2. Work on a Sub-Project:

   • Navigate to a project directory: cd <project_name>
   • Install its dependencies: uv sync

3. Enable Shared Logging (Recommended):

   • To use the shared logging library, link it to the project: uv add ../common --editable
   • This only needs to be done once per sub-project.

4. Run the Code:

   • uv run main.py (or similar).
   • Use the -v or -vv flags to increase log verbosity.

Common Logging Library

The common library provides standardized logging with colored output. Add this to scripts by running uv add ../common --editable in the project directory. The template.py script has a minimal setup implementation so from your project directory:

cp ../template.py your_script.py

Usage

After setting it up (step 3 above), modify your main script to use the logging helpers. There are three main levels:

• logger.notice(): For essential user-facing messages. Always visible by default.
• logger.info(): For detailed diagnostic messages. Visible with -v.
• logger.debug(): For verbose debugging messages. Visible with -vv.
