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
OpenCode
go install github.com/opencode-ai/opencode@latest
Comparison
| Feature | Claude Code | Codex | Gemini CLI | OpenCode |
|---|---|---|---|---|
| Session Resume | Yes | Yes | No | Yes |
| Thinking Mode | Yes | Yes | No | Yes |
| Slash Commands | Yes | No | No | No |
If no providers are detected, the agent shows a warning. Verify installation by running the provider command directly (e.g. claude --version).
