- Coding agents enhance LLMs using tools, memory, and repository context to improve performance for software tasks.
- The six main components of a coding agent are live repo context, prompt shape and cache reuse, tool access and use, minimizing context bloat, structured session memory, and delegation with bounded subagents.
- An agent harness is the software scaffold that manages context, tools, and execution, distinguishing coding agents from plain LLM interfaces like chat.
- Coding harnesses make reasoning and non-reasoning models more effective by handling context management, reducing repetitive work, and enabling tool execution.
- Key challenges include managing context bloat through clipping and summarization, and ensuring safe tool use with validation and permissions.
- Coding agents are specialized for software engineering, while platforms like OpenClaw are broader, general agent systems that include coding as one workload.
