🧠 Two-tier-memory: Long-term memory for AI agents

The open-source project Two-tier-memory has been introduced, addressing the limited context window problem of AI agents (e.g., Claude Code). The system uses a two-stage architecture: a compact index (Tier 1) and a SQLite database (Tier 2) for storing details.

🌍 The project allows for scaling task complexity without a sharp increase in token costs through structured search.

👤 The tool helps AI agents "not forget" solutions to old problems by using a local knowledge base.
