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.

Provides full markdown-based agent definitions with transparent system prompts (no hidden framework instructions), paired with Claude Agent SDK integration and MCP-based tools. Supports both local TUI and multi-user web deployment from the same runtime, featuring persistent memory, sub-agent delegation, and optional sandbox execution—all configurable via standard YAML.
