Jerry

Jerry Framework
A Claude Code plugin for behavior and workflow guardrails with knowledge accrual.

What is Jerry?

Jerry is a Claude Code plugin that adds structured problem-solving capabilities, work tracking, and knowledge management to your Claude Code sessions. It combats Context Rot—the phenomenon where LLM performance degrades as context fills—through persistent artifacts and filesystem-based memory.
Note: You do NOT need Python installed to use Jerry. The plugin runs within Claude Code using its built-in capabilities. Python is only required if you want to contribute to Jerry's development.
