Mastra Code

Mastra Code is an open-source terminal-based coding agent designed to enhance developer productivity by maintaining context over extended coding sessions. Unlike traditional coding agents that may lose context due to limitations like context window sizes, Mastra Code utilizes observational memory to compress context without losing critical information, ensuring a seamless and continuous development experience.

Observational Memory

Observational Memory is Mastra's innovative memory system designed for long-context agentic memory. It utilizes two background agents—an Observer and a Reflector—to monitor agent conversations and maintain a dense observation log, effectively replacing raw message history as it grows. This approach enhances performance by compressing context and ensuring a stable context window.
