Building agent memory that survives between sessions

File-based memory architectures with short routing files let Claude Code agents maintain persistent state across sessions by applying the 'Lost in the Middle' principle to prevent context-window attention degradation.

The article examines how practitioners build persistent memory systems for Claude Code, which loses context between sessions. It highlights Teresa Torres's three-layer system (global CLAUDE.md, project-specific instructions, reference files) and Patrick Zandl's claudecode-kb implementation (file-based routing with JSONL session logs). Both approaches apply the 'Lost in the Middle' principle from LLM research, keeping routing files short to avoid attention degradation.

AgentFloor: How Far Up the tool use Ladder Can Small Open-Weight Models Go?

AgentFloor establishes that small open-weight models can tackle more complex tool-use and agentic tasks than expected, mapping the capability ceiling across model scales.
