Summary

Adds server.exclusive option to AgentOptions to enable exclusive mode for single-agent execution without interference. When enabled, the server rejects new requests while an agent is running. (close: #1148)

Changes:

  • Added exclusive?: boolean option to AgentServerOptions.server
  • Implemented exclusive mode state management in AgentServer
  • Added request validation in session and oneshot controllers
  • Returns HTTP 409 when new requests are blocked in exclusive mode
  • NEW: Added CLI support with --server.exclusive option
  • NEW: Enhanced config builder to handle server options from CLI

CLI Usage:

# Enable exclusive mode via CLI
tarko start --server.exclusive

# Combined with other options
tarko start --server.exclusive --port 3000 --model.provider openai

API Response:

When requests are blocked in exclusive mode:

{
  "error": "Server is in exclusive mode and another session is currently running",
  "runningSessionId": "session-id-123"
}
