About
A background AI agent that gives Claude Code persistent memory by watching coding sessions, reading codebases, and whispering contextual guidance across projects. Built as a demo for the Letta Code SDK, it creates a subconscious layer that learns and remembers between Claude Code sessions.
What it can do
Monitor coding sessions in background
Active Claude Code session data → Session activity logs and metadata
Build persistent memory across sessions
Coding patterns, preferences, and session history → Accumulated knowledge base and user profile
Read and analyze codebases
Source code files and project structure → Codebase understanding and context mapping
Provide contextual coding guidance
Current coding context and historical memory → Relevant suggestions and recommendations
Remember project details between sessions
Project-specific information and code changes → Persistent project memory and context
Deliver whispered contextual hints
Real-time coding activity and stored context → Subtle guidance messages and suggestions
Why it made the leaderboard
This introduces a genuinely novel concept - a persistent 'subconscious' agent that builds memory across Claude Code sessions and provides contextual guidance. While it's a demo app, the idea of background agents that learn from coding patterns and whisper insights is differentiated from existing Claude Code extensions. The implementation using Letta's SDK for persistent memory and cross-session learning represents meaningful innovation in AI development workflow.
