Overview
You need at least one AI coding tool installed on the machine running the agent. The agent auto-detects installed providers at startup.
Claude Code (Recommended)
npm install -g @anthropic-ai/claude-code
Supports session resume, thinking mode, slash commands, and multiple AI modes.
Codex
npm install -g @openai/codex
GitHub Copilot
Install the GitHub Copilot CLI. You must be signed in to an account with an active Copilot subscription.
Gemini CLI
Install the Gemini CLI and authenticate with your Google account.
OpenCode
go install github.com/opencode-ai/opencode@latest
Comparison
| Feature | Claude Code | Codex | Copilot | Gemini CLI | OpenCode |
|---|---|---|---|---|---|
| Session Resume | Yes | Yes | Yes | Yes | Yes |
| Thinking Mode | Yes | Yes | Yes | Yes | Yes |

If no providers are detected, the agent shows a warning. Verify installation by running the provider command directly (e.g. claude --version).
