From 4e3404aae37022ac505ddd5f9d72f5e97db23d12 Mon Sep 17 00:00:00 2001 From: Brian Date: Fri, 27 Mar 2026 02:40:27 -0400 Subject: [PATCH 1/3] feat(cmd): add info command to display supported agents and runtimes Add `kortex-cli info` command that shows CLI version, available agents, and available runtimes. Agents are dynamically discovered from config files on disk (*.json in the podman config directory, excluding image.json). Supports `--output json` for machine-readable output. Also adds `ListAgents()` method to the podman config interface to enable agent discovery by scanning the config directory.
