Onboard Agent

This is scaffolding for agent systems, not individual prompts. It walks you through conventions first (delimiters, tool naming, logging format), then sets up the file structure (prompts/, tools/, tests/), then creates your first agent with a golden test case. The mandate to invoke /agent-workflow and run /teach-maestro if no context exists tells you this is meant for greenfield projects or adding agents to established workflows. Smart that it pushes you toward minimal viable tooling instead of overbuilding. If you're spinning up a multi-agent system or joining one mid-flight, this gives you the checklist so you don't skip the boring parts that matter later.
