Agents

The Agents page is a detection panel for AI coding agents installed on your machine. It scans your PATH and known install locations for supported CLI agents and shows their installation status, version, and protocol.

Detected Agents

The page auto-detects the following agents:

AgentBinary
Claude Codeclaude
OpenAI Codexcodex
GitHub Copilot CLIgh copilot
Cursorcursor-agent
OpenCodeopencode
Goosegoose
Gemini CLIgemini
Aideraider
Amazon Q Developerq
Warpwarp-agent
Open Interpreterinterpreter
Clinecline
Forgeforge
Qwen Codeqwen-coder

Each card shows the agent name, binary path, description, protocol (stdio or http), and install status. If a version is detected, it is shown on the installed badge.

Protocol Badges

Each agent is tagged with its communication protocol:

  • stdio — communicates over standard input/output; the harness spawns the process and reads its stream
  • http — communicates over a local HTTP server; the harness connects to a running process

Add to Comparator

Installed agents can be added to the Comparator from this page. Click Add to Comparator on any installed agent card to stage it for the next evaluation run. The button is disabled for agents that are not installed.

For agents that are not installed, each card shows a How to install link that opens the agent's official documentation in your browser.
