geekatronA Claude Code plugin for behavior and workflow guardrails with knowledge accrual.
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.
"The effective context window where models perform optimally is often <256k tokens, far below advertised limits." — Chroma Research

Jerry is primarily developed and tested on macOS. We are actively working on cross-platform portability, with Windows support as the immediate priority.
| Platform | Status |
|---|---|
| macOS | Primary — fully supported |
| Linux | Expected to work — not regularly tested |
| Windows | In progress — core functionality works, edge cases may exist |
