Simple Long Horizon Agent

I built an on-demand skill runtime for Simple Long Horizon Agent with package discovery, compact prompt menus, explicit skill selection, and a bundled reusable skill library.

I also unified four agent presets behind a composable AgentSession/toolset API, standardizing session and tool lifecycles while adding config-driven MCP support to evaluation runners.

This is a collaborative project; I am not its primary contributor.
