Show HN: Local knowledge vault plugin for Claude Code (github.com)

A new plugin, Agent Cortex, has been introduced for Claude Code, aimed at addressing the issue of persistent memory in AI interactions. Traditionally, Claude forgets all context between sessions, necessitating repetitive explanations about project details. Agent Cortex enables Claude to store and retrieve information across sessions using structured markdown files, organized into categories like domain knowledge, working memory, and agent identity. This simplicity lets users operate without complex databases or servers, while maintaining complete ownership of their data. The significance of this development lies in its potential to enhance productivity for developers who frequently interact with Claude Code. By allowing the AI to remember decisions, architectural choices, and recurring patterns, users can streamline their workflow and minimize redundancy. Key features include proactive saving commands, targeted knowledge scoping per project, and a simple retrieval system, which establishes a more conversational and efficient relationship between users and AI. This advancement not only elevates the functionality of Claude Code but also represents a step forward in making AI more contextually aware and integrated into ongoing projects.
