// Package main is the entry point for the agentctl binary.

// agentctl is a sidecar process that manages agent subprocess communication
|
|
// via HTTP API, bridging the agent's ACP protocol with the kandev backend.
|
|
//
|
|
// agentctl is runtime-agnostic - it behaves identically whether running
|
|
// inside a Docker container or directly on the host machine. The caller
|
|
// (kandev backend) handles any Docker vs standalone differences.
