Agent Scaffold Builder
Produces a complete AI agent scaffold — charter, system prompt, SKILL.md, tool map, guardrails, runbook, and test suite — from a one-line job description. Use when the user says "build an AI agent for X", "scaffold a new agent", "write a system prompt and SKILL.md", "design an agent's guardrails", or "make an agent workflow runbook". Do not use when the user just wants a single prompt with no full agent architecture.
