UnverifiedA workable AI harness typically contains four layers: the context layer, the orchestration layer, the tool layer, and the verification layer, which are decoupled from one another and can be replaced independently.74% similarVerifiedThe core ai package provides unified underlying capabilities including model invocation, streaming processing, and tool calling.73% similarUnverifiedThe AI system can be broken down into four layers: at the bottom is the large model (such as DeepSeek, ChatGPT), above it is the Harness, above that is the agent, and at the top is an agent platform like WorkBuddy.72% similarUnverifiedThere are usually two paths for having AI invoke the Kali toolchain: through a command-line interface where AI generates and executes commands, reads the output, and then decides the next step; or through the MCP protocol, which wraps tools into capability interfaces that AI can directly recognize.71% similarUnverifiedThe fx adapter of HarnessAgent in AI SDK underwent an architecture-level refactor: harness and model requests no longer run in the sandbox but run in the same process as the application.71% similar
