Is the memory retrieval slow as the file grows?

No, the skill features a native Rust core designed for sub-millisecond operations, ensuring that semantic searches remain instant regardless of project size.

How do I share my project's context with my teammates?

You can simply commit the .claude/mind.mv2 file to your Git repository or share it via scp to give your team instant access to the project's history and learnings.

Do I need to set up a database like SQLite or ChromaDB?

No, Claude Brain uses a single portable .mv2 file powered by a native Rust core, requiring no external database infrastructure or complex setup.

Can I ask Claude natural language questions about past work?

Yes, using the bundled ask script, you can query your memory using natural language to retrieve context on why specific choices were made or how a problem was solved.

What kind of information does the memory system store?

It automatically captures and classifies discoveries, architectural decisions, encountered problems, implemented solutions, code patterns, and successful outcomes.

Productivity & Workflow

Equips Claude with a portable, high-performance semantic memory stored in a single file for seamless context persistence across development sessions.

Claude Brain provides a robust long-term memory solution that allows Claude to retain project context, architectural decisions, and bug fixes without the need for complex external databases. Built on a high-speed Rust core, it stores all observations in a single, git-friendly .mv2 file, enabling developers to share project knowledge across teams or maintain continuity between disconnected coding sessions. By automatically categorizing information into types like decisions, patterns, and solutions, it creates a searchable 'collective brain' that enhances Claude's reasoning capabilities over time.
