BUILDING YOUR OWN CLI CODING AGENT WITH PYDANTIC-AI

Summary from the TLDR Web Dev newsletter

This is a tutorial on building a custom CLI coding agent using Pydantic-AI and an MCP that can read code, run tests, and update codebases. The author chose to build their own agent rather than using commercial tools because it allows for customization to their specific dev environment, standards, and project requirements. The implementation uses Claude as the foundation model and adds capabilities like automated testing, development guidelines through instructions, and extensible tools through MCP servers.
