  • Full visibility of thinking, tool calls, tokens, and cost
  • Configure plugins, skills, MCP servers, and hooks in a single harness.yaml file
  • Observatory: monitor every session, tool call, and minute of activity
  • Memory: persistent knowledge graph for AI orientation
  • Comparator: run prompts across Claude Code, Cursor, and Copilot side by side
  • Import existing configs from multiple AI coding tools automatically
  • Share complete setup via single file with teammates
  • Harness Parity: verify all connected AI tools end up with identical configuration
  • Cross-harness compatibility table showing actual tool capabilities
What makes it different
  • Same agent, same settings and memory — Mirafold only upgrades the interface
  • Nothing the terminal shows is lost — full superset of output
  • All MIT open source including the relay code
  • Works entirely locally with no agent modifications needed
  • Import-first approach: reads existing configs from all your tools and converges them before you write YAML
  • No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
  • Portable across tools: single harness.yaml travels with you to every machine and tool
  • Open source and free: no cost beyond existing Claude subscription
  • Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
