Components of A Coding Agent
Summary
Sebastian Raschka explains six core components of coding agents and how a harness layer around LLMs uses repo context, tools, memory, and context management to boost practical coding tasks. The piece contrasts coding harnesses with plain chat interfaces and with other systems like Claude Code, and provides concrete Python examples (Mini Coding Agent) and a discussion of memory, context minimization, and subagents. It also situates this within broader AI tool design and promotes his new book.
