About SuperQode
SuperQode functions as a harness interoperability layer for coding agents, enabling discovery, building, running, evaluation, and optimization of coding-agent harnesses from a single terminal interface. It supports multiple agent protocols including A2A, ACP, MCP, and UHP, allowing different coding agents to interact without direct communication between them. The tool provides a unified terminal-first environment where users can connect to agents, browse the Harness Hub, and call agents via standardized protocols. Evidence of agent performance is portable and verified through TCK compliance, with a 96.4% overall score. The system supports both open-source and proprietary harnesses, local and remote model providers, and multiple memory and search backends. Users can drive any ACP agent, connect via A2A clients, or serve their own harness as an A2A agent. The Harness Hub contains 72 harnesses, including 43 open-source options, and supports BYOK providers across different protocols.

Frequently asked questions about SuperQode
What is SuperQode and what does it do?
SuperQode is a harness interoperability layer designed for coding agents, enabling users to discover, build, run, evaluate, and optimize coding-agent harnesses from a single terminal interface. It supports multiple agent protocols including A2A, ACP, MCP, and UHP, allowing different coding agents to interact without direct communication.
Who should use SuperQode?
SuperQode is suitable for developers, teams, or organizations working with coding agents who need a unified terminal-first environment to manage multiple agents, protocols, and harnesses. It is particularly useful for those who want to avoid vendor lock-in and maintain flexibility across different agent ecosystems.
How does SuperQode work with different coding agents?
SuperQode acts as an intermediary layer around existing coding agents, allowing users to connect to agents via standardized protocols like A2A, ACP, MCP, and UHP. It provides a unified interface to browse the Harness Hub, call agents, and manage evidence of agent performance without requiring direct communication between agents.
What protocols does SuperQode support?
SuperQode supports four major agent protocols: A2A (Agent2Agent), ACP (Agent Client Protocol), MCP (Model Context Protocol), and UHP (Unified Harness Protocol). This allows it to interoperate with a wide range of coding agents and tools.
Can I use SuperQode with my own coding agent or harness?
Yes, SuperQode supports both open-source and proprietary harnesses, as well as local and remote model providers. Users can serve their own harness as an A2A agent or drive any ACP agent through the terminal interface.
What is the Harness Hub, and how does it help?
The Harness Hub is a repository within SuperQode that contains 72 harnesses, including 43 open-source options. It allows users to browse, discover, and select harnesses for their coding agents, with evidence of performance verified through TCK compliance.
