# A2CR

> Use this tool when you need to maintain persistent context across AI coding sessions, enabling seamless resumption of long tasks and secure storage of temporary notes. A2CR solves problems of lost progress and context switching, providing a secure interface for inputs like encrypted resume checkpoints and outputs like resumed tasks. It is ideal for use cases involving multiple sessions with AI coding agents like Claude Code, Codex, and Roo Code.

## Description

A2CR provides AI coding agents with persistent context across sessions through two mechanisms: WorkBaton, which stores encrypted resume checkpoints for resuming long tasks in fresh sessions, and WorkStash, for temporary cross-session notes. Client-side encryption ensures the server stores only ciphertext, supporting Claude Code, Codex, and Roo Code.
