Adding New Agents

RAPID can work with any CLI-based AI tool:

{
  "agents": {
    "available": {
      "custom-agent": {
        "cli": "my-ai-tool",
        "instructionFile": "MY_AGENT.md",
        "envVars": ["MY_API_KEY"],
        "installCmd": "npm install -g my-ai-tool",
        "args": ["--flag", "value"]
      }
    }
  }
}

Requirements

For an agent to work with RAPID:

CLI interface - Must be runnable from command line
Environment variables - Must read API keys from env
Interactive mode - Must support chat/interactive session
Exit cleanly - Must handle SIGTERM gracefully

Troubleshooting

Agent not starting

# Verify installation
which claude
which aider

# Check env vars
echo $ANTHROPIC_API_KEY

# Reinstall
rapid start --reinstall-tools

Slow response times

Check model selection (Opus slower than Sonnet)
Reduce context window
Use faster model for simple tasks

Rate limiting

Implement request queuing
Use multiple API keys
Switch to different provider
