agent harness

VAEN is a CLI for packaging AI coding-agent setups into portable .agent archives and importing them across repos or teams without copying instructions, skills, MCP config, or secrets.

agentpack is a tool for staging reproducible AI coding environments across agent harnesses like Claude Code, Codex, Cursor, and OpenCode. It manages skills, hooks, MCPs, and other agent configuration from a single manifest without polluting the project or user config.
