Claude-Mem is a persistent memory compression system designed specifically for Claude Code and Gemini CLI. It automatically captures tool usage observations, generates semantic summaries via AI, and injects relevant context into future sessions to ensure continuity of knowledge across coding projects.
Key features include:
* Persistent memory that survives session restarts
* Progressive disclosure architecture for token-efficient retrieval
* Skill-based search using MCP tools (search, timeline, get_observations)
* Hybrid semantic and keyword search powered by Chroma vector database and SQLite
* Privacy controls via specific tags to exclude sensitive data
* A web viewer UI for real-time memory stream monitoring

This article explores the concept of an "agent harness," the essential software infrastructure that wraps around a Large Language Model (LLM) to enable autonomous, goal-directed behavior. While foundation models provide the core reasoning capabilities, the harness manages the orchestration loop, tool integration, memory, context management, state persistence, and error handling. The author breaks down the eleven critical components of a production-grade harness, drawing insights from industry leaders such as Anthropic, OpenAI, and LangChain. By comparing the harness to an operating system and the LLM to a CPU, the piece provides a technical framework for understanding how to move from simple demos to robust, production-ready AI agents.
