About harness
mastersof-ai/harness
Agent runtime with full system prompt control. Define agents in markdown, run them in a terminal TUI or multi-user web UI. Powered by the Claude Agent SDK.
This tool helps professionals create and manage AI agents for various tasks without needing to write code. You define an agent's instructions, personality, and workflow using a simple Markdown file, and the system brings that agent to life. The output is an AI agent that acts exactly as you've described, ready for use by individuals or teams through a terminal or web interface. Anyone who needs a custom AI assistant for research, analysis, writing, or problem-solving, like a market analyst, a researcher, or a content creator, would find this useful.
